Human Growth Hormone: What is HGH and What Does it Do?

The preponderance of research to date suggests that exercise-induced reactive oxygen species and nitric oxide are beneficial. These free radicals induce adaptive changes in muscle that lead to greater production of mitochondria and hypertrophy of myofibers [17,21,23,24]. Exposure of cells to high concentrations of various antioxidant supplements (of which vitamins C and/or E have the most evidence) appears to blunt or block cell signaling and thereby inhibit some favorable physiological and physical adaptations to exercise. However, these adaptations might not prevent improvements in VO2max or endurance performance [25].

  • In the United States, the only FDA-approved use of GH for livestock is the use of a cow-specific form of GH called bovine somatotropin for increasing milk production in dairy cows.
  • Supplementation with creatine over weeks or months helps training adaptations to structured, increased workloads over time.
  • The National Collegiate Athletic Association prohibits use of caffeine from any source in amounts that would lead to urine concentrations exceeding 15 mcg/ml [104,105].
  • Somatropin has direct tissue and metabolic effects or mediated indirectly by IGF-1, including stimulation of chondrocyte differentiation, and proliferation, stimulation of hepatic glucose output, protein synthesis and lipolysis.
  • In some cases, the products contain proprietary blends of ingredients listed in order by weight, but labels do not provide the amount of each ingredient in the blend.

This supplementation could be used in multi-day competitions that are common for endurance athletes. The potential mechanisms responsible for the ergogenic effect include the alleviation of central fatigue by BCAA and the prevention of hyperammonemia through increased urea genesis by arginine and citrulline. Future studies could examine the role of other neurotransmitters such as dopamine and epinephrine. In addition, the effect of this supplementation on fed state requires further investigation. Because the research results are conflicting, the activities and individuals most likely to benefit from sodium bicarbonate supplementation in real-world conditions is not clear.

HGH and Cardiovascular Health

Also, when taking more than 4 IU’s of HGH per day, try dividing it into two doses; one in the AM upon rising and the other half at 4 p.m. One more thing to consider when you buy HGH is that the real version only comes in lyophilized powder, and it must be administered through subcutaneous (into the fat just under the skin) injections. You’ll often see some different products offered, ranging from HGH pills to HGH spray – these are complete garbage! Somatropin is a fragile molecule that’s really unstable and doesn’t stay composed very long at room temperature.

  • This supplementation could be used in multi-day competitions that are common for endurance athletes.
  • The short-term or longer term use of the supplement did not affect serum testosterone concentrations, nor did it produce any significantly greater gains in resistance-training performance, muscle strength, or lean body mass.
  • Another bonus to Human Growth Hormone is that it helps you recover from both workouts and heal from injuries faster.
  • Even raised HGH secretion, however, might not translate into more blood flow into muscle or greater protein synthesis [31].

These studies usually included a small number of participants who underwent one or more trials in a laboratory over several days. The authors of the short-term studies investigating ribose as a potential ergogenic aid have not reported any safety concerns. No studies have assessed the safety of long-term ribose use as a dietary supplement.

Watermelon is the best-known source; 1 cup diced seedless watermelon has about 365 mg citrulline [108]. About 80% of the body’s citrulline is converted in the kidneys into arginine, another amino acid (see section on arginine) [30]. The subsequent conversion of arginine to nitric oxide, a potent dilator of blood vessels, might be the mechanism by which citrulline could serve as an ergogenic aid.

  • These organizations add that the best way to use supplements is as additions to a carefully chosen diet, that dietary supplements rarely have ergogenic benefits when not used in these conditions, and that there is no justification for their use by young athletes.
  • Think of AAS as regular-grade gasoline, adding HGH would turn them into higher, premium-grade fuel.
  • In this way, caffeine enhances arousal, increases vigor, and reduces fatigue [13,85,86].
  • Mean fasting serum insulin concentration increased by 10% in the HUMATROPE treatment group at the end of treatment relative to baseline, but remained within the normal reference range.

Humatrope is synthesized in a strain of Escherichia coli that has been modified by the addition of the gene for human GH. The peptide is comprised of 191 amino acid residues and has a molecular weight of about 22,125 daltons. The amino acid sequence of the peptide is identical to that of human GH of pituitary origin. It stimulates the liver to make an insulin-like protein that produces cartilage cells. This structure is very similar to the natural HGH in the human body, which leads to a small number of side effects Ansomone can cause. Growth hormone deficiency (GHD) is caused by insufficient amounts of GH in the body.

Estimated dietary intakes range from none in vegans to about 1 g/day in heavy meat eaters [52]. However, oral consumption of carnosine is an inefficient method of increasing muscle carnosine concentrations because the dipeptide is digested into its constituent amino acids. Consumption of beta-alanine, in contrast, reliably increases the amount of carnosine in the body. Four to six grams of beta-alanine for 10 weeks, for example, can increase muscle carnosine levels by up to 80%, especially in trained athletes, although the magnitude of response differs widely [53,54]. For example, in one study of young, physically active but untrained adult men who took 4.8 g/day beta-alanine for 5–6 weeks, the percent increase in muscle carnosine content after 9 weeks of follow-up ranged from 2% to 69% [55]. Among the low responders, the duration of the washout period when beta alanine concentrations returned to baseline values was less than half that for the high responders (6 weeks vs. 15 weeks).

Effects of Ansomone HGH

For example, a dose (either three or four IU) can be taken post training with another three to four IU dose before bed or during the night sleeping period. » « GH », Says Ali, « has a half-life of 15 to 20 minutes after sub-q (subcutaneous) or intravenous injection. After that, blood concentrations of HGH reach their peak between one and three hours after injection. » « GH diverts calories in food towards protein synthesis and away from fat synthesis as demonstrated in animal tests. It is as powerful as testosterone in stimulating protein synthesis properties. » This information does not take the place of talking to your healthcare provider about your or your child’s medical condition or treatment.

Use of HMB did not alter or adversely affect any measured hematologic, hepatic, or renal-function parameters in these young men. Although 3 g/day HMB appears to be safe for short-term use in adults, its safety profile (and efficacy) has not been studied in adolescents [63]. There is insufficient expert consensus on the value of taking beta-alanine to enhance performance in intense, short-term activities or its safety, particularly when users take it regularly for at least several months. In its position statement, the ISSN concludes that beta-alanine supplementation improves exercise performance and attenuates neuromuscular fatigue [54]. Table 1 briefly summarizes the findings discussed in more detail in this fact sheet on the safety and efficacy of selected ingredients in dietary supplements to enhance exercise and athletic performance. Some research-derived data are available on these ingredients on which to base a judgment about their potential value to aid exercise and athletic performance.

So while HGH 191AA refers to the specific amino acid sequence of the hormone, HGH GMP 98% refers to the quality and purity of the HGH product. It’s possible to have HGH that is both 191AA and GMP 98%, but they are not the same thing. The AA trial resulted in increases in post-exercise plasma BCAA concentrations by 71.1% and 60.4% on day 1 and 2, respectively, compared to the baseline (Figure 3A). Post-exercise plasma tryptophan levels were significantly increased from the baseline on both days in the PL trial, while it was increased only on day 2 in the AA trial (Figure 3B). The larger magnitude of BCAA increase led to the significantly lower post-exercise tryptophan/BCAA ratio in the AA trial, compared to that in the PL trial (Figure 3C). As mentioned before, GH is secreted by the pituitary gland, usually when you’re sleeping or during high-intensity workouts.
