You can't push the body past where it begins to break down without devastating consequences. However, if you preload and pump working muscles full of critical nutrients, you can significantly boost performance while minimizing damage and inflammation. You can train harder and recover faster.

Taking Plazma™ doses — before, during, and after training — keeps muscles pumped full of the key nutrients for maximum performance and enhanced recovery. The term for this muscle-engorging effect is called the "reactive pump." The reactive pump makes muscles hyper-responsive to nutrient uptake and growth signaling, producing unbreakable performances in the gym and competitions.

Here's feedback from two fitness legends: Dave Tate and John Meadows.

"You get leaner almost daily while gaining muscle and strength."

Dave Tate in gym with pumped arms

When Biotest CEO Tim Patterson first asked me about trying Plazma™ dosing, I was extremely skeptical. But I took him at his word, gave it a shot, and was completely blown away by the results. In fact, I contribute much of my recent success to Biotest's Plazma™ formula. It flat out works. You get leaner almost daily while gaining muscle and strength. It's nuts.

I feel like the Plazma™ protocol buys me considerable leeway. I can basically screw up my diet everywhere else, and as long as I take this supplement, I'll meet my body's needs and grow. That's a huge plus for me. I have enough to think about, so the last thing I want is to be stressed about what I eat. It's nice knowing that as long as I have Plazma™ during my workout, I can basically cruise through the rest of the day. So if anything, this workout protocol is a huge stress reliever.

"I feel like I'm unbreakable."

John Meadows's physique

Testing the Plazma™ formula, I did things that I'd never advise anybody to do, like crazy intensity and insane volume. I didn't cramp up, I didn't get sore, and I got these mind-blowing pumps.

For the next three weeks, I kept training like this and eating a lot to see how much muscle I could gain. Getting leaner wasn't even on my mind. So when my body fat dropped from about 9 percent to 5 or 6 percent, it was pretty much by accident.

It was so amazing. All I have to do is follow the Plazma™ protocol and go to the gym and train my ass off, which I love to do. That's it. And to think, I pretty much got in shape by accident.

PMID: 33369793 DOI: 10.1113/EP088770. New findings: What is the central question of this study? Previously, we have shown that supplementation of Lactobacillus helveticus-fermented milk and milk casein hydrolysate (MCH) improves glucose metabolism in exercised mice and humans. Common active ingredients contained in both Lactobacillus helveticus-fermented milk and MCH may enhance glucose metabolism, but the details are yet to be clarified. What is the main finding and its importance? MCH enhanced glucose uptake in skeletal muscle cells by stimulating AMP-activated kinase (AMPK), but not insulin signaling. Moreover, the MCH-derived specific peptide, Ile-Pro-Pro, mimicked this effect, suggesting a mechanism for the MCH-induced metabolic improvement. ABSTRACT: Improvement of glucose metabolism in the skeletal muscle has a key role in exercise performance and prevention of metabolic diseases. In our previous study, we had shown that intake of milk casein hydrolysate improves glucose metabolism in humans, but the mechanism of action was not elucidated. In this study, we aimed to investigate the mechanism of action of milk casein hydrolysate and its derived peptides on glucose uptake and glucose metabolic signaling in cultured skeletal muscle cells. Differentiated C2C12 myotubes were used for the experiments. The differentiated cells were incubated with milk casein hydrolysate, valine-proline-proline, and isoleucine-proline-proline. Subsequently, the rate of 2-deoxy-glucose uptake and the phosphorylation levels of insulin-dependent and -independent signaling factors were examined. We found that the rate of 2-deoxy-glucose uptake in both milk casein hydrolysate and isoleucine-proline-proline-treated cells was higher than that in the control cells. Immunoblotting assays showed that the phosphorylation levels of AMP-activated protein kinase, a rate-limiting factor in insulin-independent signaling, and that of liver kinase B1, an upstream factor of AMP-activated protein kinase, in both milk casein hydrolysate and isoleucine-proline-proline-treated cells were higher than those in the control cells. Such significant effects were not observed after treatment with valine-proline-proline. Moreover, the insulin-dependent signaling was not significantly affected under the different conditions. The findings of our study suggest that milk casein hydrolysate enhances glucose uptake by activating insulin-independent AMP-activated protein kinase signaling in skeletal muscle cells, which might be mediated by a milk casein hydrolysate-derived peptide, namely, isoleucine-proline-proline.

PMID: 19478339 DOI: 10.1123/ijsnem.19.2.136. ABSTRACT: This study examined whether a carbohydrate + casein hydrolysate (CHO+ProH) beverage improved time-trial performance vs. a CHO beverage delivering approximately 60 g CHO/hr. Markers of muscle disruption and recovery were also assessed. Thirteen male cyclists (VO2peak = 60.8 +/- 1.6 ml . kg-1 . min-1) completed 2 computer-simulated 60-km time trials consisting of 3 laps of a 20-km course concluding with a 5-km climb (approximately 5% grade). Participants consumed 200 ml of CHO (6%) or CHO+ProH beverage (6% + 1.8% protein hydrolysate) every 5 km and 500 ml of beverage immediately postexercise. Beverage treatments were administered using a randomly counterbalanced, double-blind design. Plasma creatine phosphokinase (CK) and muscle-soreness ratings were assessed immediately before and 24 hr after cycling. Mean 60-km times were 134.4 +/- 4.6 and 135.0 +/- 4.0 min for CHO+ProH and CHO beverages, respectively. All time differences between treatments occurred during the final lap, with protein hydrolysate ingestion explaining a significant (p < .05) proportion of between-trials differences over the final 20 km (44.3 +/- 1.6, 45.0 +/- 1.6 min) and final 5 km (16.5 +/- 0.6, 16.9 +/- 0.6 min). Plasma CK levels and muscle-soreness ratings increased significantly after the CHO trial (161 +/- 53, 399 +/- 175 U/L; 15.8 +/- 5.1, 37.6 +/- 5.7 mm) but not the CHO+ProH trial (115 +/- 21, 262 +/- 88 U/L; 20.9 +/- 5.3, 32.2 +/- 7.1 mm). Late-exercise time-trial performance was enhanced with CHO+ProH beverage ingestion compared with a beverage containing CHO provided at maximal exogenous oxidation rates during exercise. CHO+ProH ingestion also prevented increases in plasma CK and muscle soreness after exercise.

Ann Nutr Metab. 2000;44(1):21-9. PMID: 10838463 DOI: 10.1159/000012817. ABSTRACT: We compare the effects of a moderate hypocaloric, high-protein diet and resistance training, using two different protein supplements, versus hypocaloric diet alone on body compositional changes in overweight police officers. A randomized, prospective 12-week study was performed comparing the changes in body composition produced by three different treatment modalities in three study groups. One group (n = 10) was placed on a nonlipogenic, hypocaloric diet alone (80% of predicted needs). A second group (n = 14) was placed on the hypocaloric diet plus resistance exercise plus a high-protein intake (1.5 g/kg/day) using a casein protein hydrolysate. In the third group (n = 14) treatment was identical to the second, except for the use of a whey protein hydrolysate. We found that weight loss was approximately 2.5 kg in all three groups. Mean percent body fat with diet alone decreased from a baseline of 27 +/- 1.8 to 25 +/- 1.3% at 12 weeks. With diet, exercise and casein the decrease was from 26 +/- 1.7 to 18 +/- 1.1% and with diet, exercise and whey protein the decrease was from 27 +/- 1.6 to 23 +/- 1.3%. The mean fat loss was 2. 5 +/- 0.6, 7.0 +/- 2.1 and 4.2 +/- 0.9 kg in the three groups, respectively. Lean mass gains in the three groups did not change for diet alone, versus gains of 4 +/- 1.4 and 2 +/- 0.7 kg in the casein and whey groups, respectively. Mean increase in strength for chest, shoulder and legs was 59 +/- 9% for casein and 29 +/- 9% for whey, a significant group difference. This significant difference in body composition and strength is likely due to improved nitrogen retention and overall anticatabolic effects caused by the peptide components of the casein hydrolysate.

PMID: 32600859 DOI: 10.1016/j.clnu.2020.06.006. ABStrACT: Background: FGF-21 is described as a powerful metabolic regulator with beneficial effects including glucose-lowering and improvement of insulin sensitivity without hypoglycaemia. On the other hand, FGF-21 is activated when muscle and other tissues are stressed by external effects or internal cellular pathogens that lead to shortcomings in metabolic balance. Previous results suggested that FGF-21 could be a promising target to develop future metabolic therapeutics. Purpose: The present study was performed to gain deeper insight into the regulation of FGF-21 by protein metabolism in obese human subjects. Methods: FGF-21 serum concentrations were measured in a cohort of n = 246 obese humans ± type 2 diabetes mellitus (T2DM) (median age 53.0 [46.0; 60.0] years and BMI 40.43 [35.11; 47.24] kg/m2) and related to the nutritional protein intake. In addition, the effect of a novel oligopeptide purified from a β-casein hydrolysate on FGF-21 was examined in vitro in liver cells and in vivo in a human intervention study with the main focus on metabolic inflammation including 40 mainly obese subjects (mean age 41.08 ± 9.76 years, mean BMI 38.29 ± 9.4 kg/m2) in a randomized 20 weeks double-blind cross-over design. Main findings: In the cohort analysis, FGF-21 serum concentrations were significant lower with higher protein intake in obese subjects without T2DM but not in obese subjects with T2DM. Furthermore, relative methionine intake was inversely related to FGF-21. While global protein intake in obesity was inversely associated with FGF-21, incubation of HepG2 cells with a β-casein oligopeptide increased FGF-21 expression in vitro. This stimulatory effect was also present in vivo, since in the clinical intervention study treatment of obese subjects with the β-casein oligopeptide for 8 weeks significantly increased FGF-21 serum levels from W0 = 23.86 pg/mL to W8 = 30.54 pg/mL (p < 0.001), while no increase was found for placebo. Conclusion: While the total nutritional protein intake is inversely associated with FGF-21 serum levels, a purified and well characterised oligopeptide is able to induce FGF-21 serum levels in humans. These findings suggest a differential role of various components of protein metabolism on FGF-21, rather than this factor being solely a sensor of total nutritional protein intake.

DOI: 10.3136/fstr.21.499. ABSTRACT: Highly branched cyclic dextrin (HBCD) is a novel type of maltodextrin with a narrow molecular weight distribution that is produced from starch. In this study, we investigated the effects of HBCD administration on endurance performance. Seven elite swimmers participated in three trials, conducted in random order. In each trial, the subjects received either HBCD, glucose (1.5 g carbohydrate/kg body weight) or water (as a control), and immediately carried out 10 cycles of intermittent swimming consisting of 5 min of swimming at 75% followed by 3 min of rest, and subsequent swimming at 90% to exhaustion. The time to fatigue was about 70% longer in the HBCD trial than that in the glucose and control trials, a significant difference. Plasma glucose in the HBCD group was maintained at higher levels during pre-swimming cycles than that in the glucose or water group. These results suggest that HBCD administration enhances endurance performance.

Biosci Biotechnol Biochem. 2014;78(12):2117-9. DOI: 10.1080/09168451.2014.943654. ABSTRACT: We compared the effect of relatively low doses (15 g) of highly branched cyclic dextrin (HBCD) with that of maltodextrin during endurance exercise on the rating of perceived exertion (RPE) in a crossover, double-blind study of healthy volunteers. The RPE increased during exercise and its increase was significantly less at 30 and 60 min after ingesting HBCD than maltodextrin.

PMID: 25270782. ABSTRACT: Background: Aim of the present study was to compare the effects of highly branched cyclic dextrin (HBCD) drink with a glucose-based control drink on immunoendocrine responses to endurance exercise. Methods: Using a randomized, double-blind placebo-controlled cross-over design, seven male triathletes participated in two duathlon races separated by one month, consisting of 5 km of running, 40 km of cycling and 5 km of running. In the first race, four athletes consumed the HBCD-based drink and three athletes consumed the glucose-based drink. In the second race, three athletes consumed the HBCD-based drink and four athletes consumed the glucose-based drink. We collected blood and urine samples before and after the races to analyze leukocyte count and concentrations of hormones and cytokines. Results: Lymphocyte and neutrophil counts increased significantly after exercise in both trials (P < 0.05), but were not significantly different between the trials. Plasma noradrenalin concentration increased significantly (P < 0.05) during exercise in the glucose trial, but not in the HBCD trial. Plasma concentrations of interleukin (IL)-8 and IL-10 increased significantly during exercise in both trials (P < 0.05) but were not significantly different between the trials. Post-race urinary IL-8, IL-10 and IL-12p40 concentrations were significantly lower in the HBCD trial compared with the glucose trial (P < 0.05), although the plasma concentrations of these cytokines were not significantly different between both trials. Conclusion: These results suggest that the HBCD-based drink may attenuate the stress hormone response, and reduce the urinary cytokine levels following exhaustive exercise.
  4. Takii H et al. Fluids containing a highly branched cyclic dextrin influence the gastric emptying rate. Int J Sports Med. 2005 May;26(4):314-9. doi: 10.1055/s-2004-820999. ABSTRACT: The rates of gastric emptying for highly branched cyclic dextrin (HBCD) and other carbohydrate (CHO) solutions were examined using ultrasonograph techniques. Ten healthy volunteers ingested water, physiological saline, or solutions containing various CHO, such as HBCD, glucose, maltose, sucrose, and commercially available dextrin. After a subject drank one of the solutions, the relaxed cross-sectional area of the pylorus antrum was measured at rest by real-time ultrasonography. The time required for gastric emptying was correlated with the relaxed cross-sectional area of the pylorus antrum. Among all of the solutions tested, physiological saline was transferred fastest from the stomach to the small intestine. For solutions of the same CHO, 5% solution was transferred faster than 10% solution. For CHO solutions other than HBCD, a low osmotic pressure was associated with rapid transfer from the stomach. The gastric emptying time (GET) of HBCD solution increased with an increase in its concentration. A shorter GET was observed for the CHO solutions at 59 to 160 mOsm regardless of their concentration. A sports drink based on 10% HBCD adjusted to 150 mOsm by the addition of various minerals, vitamins, and organic acids was evacuated significantly (p < 0.05) faster than a 10% HBCD solution or a sports drink based on 10% commercially available dextrin (DE16), which has a higher osmotic pressure (269 mOsm). Our results suggest that a shorter GET could be achieved with CHO solutions with osmotic pressures of 59 - 160 mOsm. Therefore, a sports drink based on 10% HBCD adjusted to 150 mOsm by the addition of minerals, vitamins, and organic acids could supply adequate quantities of CHO, fluid, and minerals simultaneously in a short time, without increasing GET.

ABSTRACT: We investigated the ergogenic effect in mice of administering highly branched cyclic dextrin (HBCD), a new type of glucose polymer, on the swimming endurance in an adjustable-current swimming pool. Male Std ddY mice were administered a HBCD, a glucose solution or water via a stomach sonde 10 min before, 10 min after or 30 min after beginning swimming exercise, and were then obliged to swim in the pool. The total swimming period until exhaustion, an index of the swimming endurance, was measured. An ergogenic effect of HBCD was observed at a dose of 500 mg/kg of body weight, whereas it had no effect at a dose of 166 mg/kg of body wt (p < 0.05). The mice administered with the HBCD solution 10 min after starting the exercise were able to swim significantly longer (p < 0.05) than the mice who had ingested water or the glucose solution. The rise in mean blood glucose level in the mice administered with HBCD, which was measured 20 min after starting swimming, was significantly lower (p < 0.05) than that in the mice administered with glucose, although it was significantly higher (p < 0.05) than that in the mice administered with water. The mean blood insulin rise in the mice given HBCD was significantly lower (p < 0.05) than that in the mice given glucose. The mice administered with HBCD 30 min after starting the exercise swam significantly longer (p < 0.05) than the mice who had ingested water, although the enhancement of swimming time was similar to that of the glucose-ingesting mice. The gastric emptying rate of the HBCD solution was significantly faster (p < 0.05) than that of the glucose solution. However, this glucose polymer must have spent more time being absorbed because it has to be hydrolyzed before absorption, reflecting a lower and possibly longer-lasting blood glucose level. We conclude that the prolongation of swimming endurance in mice administered with HBCD depended on its rapid and longer-lasting ability for supplying glucose with a lower postprandial blood insulin response, leading to a delayed onset of fatigue.

Plazma works!

Plazma definitely works great! Finally feel recovered from tuff workouts with no stomach upsets like I get from other products I have used in the past. The pumps are amazing! I also like that I can control the sweetness level of the product.

Best supp for recovery

I’ve been using Plazma for years, and it is by far the best supplement that I have used for recovery. For me it reduces muscle soreness, and nervous system fatigue to the point where it isn’t even noticeable, which helps me to stay consistent with intense training. It is very versatile as well. I regularly use it after lifting sessions, and 3 hour Jiu Jitsu classes, and it allows me to consistently make progress in both areas. I’ve also used it when I’ve been sick and not able to keep down solid food, and before crashing after a long overnight shift at work. It’s the one supplement I never want to go without.

Great product however expensive

The product is great however the price is rather high, id like to be able to use it more however income prevents me from doing so. Using 3 servings per training day will really blast right through it, id personally use 2 before training and 1 serving a few hours before bed time. Love it the product is just pricy.

The most important ability is availability

It would great to use this with confidence that you could buy more whenever you run out.

Fantastic when it's available

I absolutely love using Plazma. I notice a substantial increase in work capacity and recovery when I'm using it, and I'm positive that I'm bigger, leaner, and stronger now than I would be in a world where I never took it. And I realize that there are supply chain issues that are out of your control, but I'd love it if you could iron out its availability issues.

I absolutely love this product. I overall enjoyed and trust Tnations supplements and really appreciate how efficiently they ship my items no matter where I’m at in the world.

So far so good

I’ve only been using it for about a week but I do think it gives me more energy for my workouts. I look forward to seeing what I think of it a month from now. At age 61 I need all the help to get through my workouts that I can. :-)

love plazma, hate auto ship

I have been a Biotest customer for years. I love the products but hate the fact that I was unable to order Plazma unless I subscribed to the new auto ship program. I don't have time to cancel or move orders. I want to order it when I need it. Not sure if I will continue using any items that fall under this parameter.

Change is not always good

Since the site and store has been upgraded.I have not been able to get my good customer 20% off.I can no longer purchase Plazma when I want,only on monthly subscription.This long time customer is somewhat disappointed

Great I take it in addition to SURGE WORKOUT FUEL. Currently doing the METCON training and doing the SURGE WORKOUT FUEL protocol and I added Plazma two servings a day in the morning when I wake up along with a Finibar and one serving after the workout. Non workout days morning and at night late usually after midnight after I go to the bathroom it’s prepared and sits on my nightstand ! It’s tremendous!!!!

I’m a bodybuilder and use this during heavy workouts like quads and glutes… makes a huge difference in stamina and strength

It's my only go to intra workout nutrition supplement because it blends great and is easy to drink during tough workouts without feeling full as you would with a protein shake or carb supplement. Been using it for maybe 7+ years now and will keep using it for years to come.

I started 1 1/2 years ago with Pulse, then switched to Plazma, I stack it now with Surge. Unbelievable performance enhancer.
