Use "Protein Pulses" for the Greatest Effects

Science and experience show that "protein pulses" make the body hyper-responsive to protein, which is why we recommend using this approach. For best effects, you have to consume Mag-10® doses in a way to achieve at least two or three sizable protein spikes per day with enough time in-between doses to allow the body to return to baseline. In practice, this means allowing at least three or four hours between Mag-10® doses.*

The increased rate of protein utilization you'll experience from Mag-10® pulses will help you gain muscle, lose fat, and recover much faster than you've ever experienced before.*

Optimal Pulsing Times

• Immediately after getting up in the morning.
• Between meals.
• After training and competition.
• One hour before bedtime.
• Any time you need an energy boost.

Pulsing During Cardio or Metcon

Many physique competitors use fasted cardio (doing cardio on an empty stomach, such as first thing in the morning) for fat loss. The idea is simple: body fat is vulnerable and can be better oxidized and burned for fuel when you're in a fasted state. But muscle is also vulnerable, which also puts your metabolism at risk.*

A Mag-10® pulse is perfect for protecting muscle from catabolism and boosting the fat-burning effects of cardio and metabolic conditioning, Dr. Lonnie Lowery confirmed in his lab. He noted, "Muscles are fully protected while fat burning remains in high gear during aerobic sessions. It's a prime example of tactical nutrition."*

Pulsing During a 24-Hour Fast Is Thermo-Anabolic

Since we had so much success using Mag-10® pulses during fasted cardio, we wanted to try them out on a semi-fast. In short, we had dieters consume several Mag-10® doses instead of eating solid foods for one entire day, then eat a regular diet the rest of the week. So they were doing Mag-10® fasts once per week for several weeks in a row.

We found that this Mag-10® fast produces more significant fat loss and muscle gains than regular un-fasted diets. Looking into the science, we believe Mag-10® fasts create a metabolic state where the body burns extra fat for fuel while building muscle.

We also found the best time for a Mag-10® fast is the day after a cheat day. You could even do one cheat day followed by a Mag-10®-fast every week for several weeks in a row. There's a T Nation article about the concept called Make Cheat Meals Work for You.*

Will Mag-10 make me fail a drug test?

No. And none of the ingredients are on WADA's banned substances list.

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.
5. Takii H et al. Enhancement of swimming endurance in mice by highly branched cyclic dextrin. Biosci Biotechnol Biochem. 1999 Dec;63(12):2045-52. DOI: 10.1271/bbb.63.2045. 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.
