Thymosin alpha-1 is one of the few peptides with genuine human trial data. It is approved in 35+ countries as Zadaxin - but not in the US. Here is what it is used for and what the research actually shows.
Sermorelin nudges your body to make its own growth hormone. It was once FDA-approved for children's growth, and is now used off-label for anti-aging and body composition. The direct human evidence is limited but promising. Here's the honest read.
Retatrutide is the next-generation weight-loss drug that hits three hormone targets at once. Trial results are striking, but it is not FDA-approved and cannot be legally compounded. Here is what the evidence actually shows.
Peptides and SARMs get lumped together online, but they are different molecules with very different safety and legal profiles. Here is the honest comparison, with what the FDA and the evidence actually say.
Copper peptides and biotinoyl tripeptide-1 are sold widely for hair loss. The supporting studies are mostly cells and animals. Here is what exists in humans, and how it compares with the two treatments that have decades of trial data.
Better sleep and more energy are standard peptide selling points. No growth-hormone secretagogue has been tested with sleep laboratory measurement, and the one peptide with a large sleep trial works by a completely different route.
Most of the peptides discussed for performance and recovery are prohibited in sport at all times. Here is exactly which WADA category each falls under, which are not listed, and why 'not listed' is not the same as safe or legal.
MOTS-c is a peptide your own mitochondria make - it rises with exercise and improves metabolism and healthspan in mice. It's genuinely fascinating science. But the evidence for taking it is still preclinical. Here's the honest read.
Melanotan II is an unapproved peptide injected or sniffed to get a tan. It does darken skin - but it is linked to changing moles and reported melanomas, and it is not approved anywhere. Here is what the evidence shows.
Kisspeptin is a natural hormone-controlling peptide being tested for low sex drive - and unlike most 'libido peptides,' it has genuine human trials. It's promising and well-tolerated, but still investigational. Here's the honest evidence.
