Bovine colostrum contains IGF-1, but three placebo-controlled studies found that oral colostrum did not raise circulating IGF-1 in healthy adults, and a 2021 review says early suggestions of an increase are not supported by the balance of evidence. HGH was…

It’s plausible, though the direct human evidence is limited. Vitamin B6 deficiency is uncommon in the general U.S. population, but animal research shows a clear drop in testosterone with B6 depletion, and B6’s role in prolactin regulation gives a reasonable…

Heat and cold both trigger strong hormonal responses, but only heat has been shown to raise growth hormone, and only briefly. In small studies from the 1980s, sauna heat raised HGH in some conditions, and the response faded after several…

In trials of pharmaceutical HGH combined with calorie restriction, HGH helped preserve lean body mass, and in one trial adults on a reduced-calorie diet gained lean mass while placebo participants lost it. Results on fat loss were mixed, and the…

In men, largely yes. The biggest daily HGH pulse typically arrives shortly after sleep onset, in association with the first phase of deep, slow-wave sleep, and about 70 percent of HGH pulses during sleep coincide with it. Experiments suggest the…

Most U.S. guidelines use a total testosterone level below 300 ng/dL as a reasonable cutoff supporting a diagnosis of low testosterone, but here’s something worth knowing: different major medical organizations actually disagree on the exact number, with published cutoffs ranging…

Deer antler velvet contains IGF-1, which is why it gets linked to growth hormone, but human trials have not shown that it raises HGH or clearly improves athletic performance. A 10-week trial in 46 rowers found no change in growth…

Your own HGH rises for about 15 to 30 minutes after a resistance workout and takes part in the body’s tissue-remodeling signals. In one trial, adding pharmaceutical HGH to resistance training did not produce extra gains in muscle protein synthesis…

It’s a genuinely good idea, even though testosterone boosters are sold over the counter without a prescription. A quick conversation with a doctor can tell you whether your symptoms actually have anything to do with testosterone in the first place,…

Growth hormone appears to support male reproductive health, but extra HGH has not been shown to improve sperm quality. Men with growth hormone deficiency showed mildly lower sperm measures in one controlled study, while small trials of pharmaceutical HGH as…
