Evidence base
Evidence base: 5 articles from Peptides Facts. Evidence-led reference on research peptides.
HCG: A Real Hormone Attached to a Refuted Diet Claim
Human chorionic gonadotropin has a defined receptor, a well-described mechanism and approved clinical uses in fertility and male endocrinology. It also carries one of the most thoroughly disproved claims in the history of obesity treatment, and the first fact is why the second one lasted.
Growth Hormone in Healthy Older Adults: One Study, and What Came After It
A 1990 report on twelve men over 60 is still the foundation of growth hormone's anti-aging reputation. The randomised trials that followed found something considerably smaller, alongside a list of harms.
Melanotan II: The Documented Safety Signals
A non-selective melanocortin receptor agonist that was never developed as a medicine. What the case-report literature records, and why the absence of controlled safety data is itself the central finding.
Epitalon and Telomerase: An Assessment of the Evidence Base
The claims made for epitalon are specific, mechanistic and testable. The evidence behind them is small, concentrated in a single research programme, and largely unreplicated. That combination is the finding.
AOD9604: A Compound That Worked in Mice and Failed in People
The rodent data were strong, the mechanism was coherent, and the human trials did not replicate it. AOD9604 is the most instructive failure in the peptide literature, and it is rarely described as one.
