Peptides for muscle gain: the evidence
Ipamorelin and CJC-1295 lead the muscle-gain peptide conversation. Here is how their evidence actually ranks, from human pharmacology to mouse data to anecdote.
Methodology
Sexual-function peptides: the evidence
Only one sexual-function peptide, bremelanotide (Vyleesi), has real trial support, and only for one use. Here is how to weigh the evidence tier by tier.
Methodology
Peptides for sleep: the evidence grade
MK-677 has a small controlled trial showing improved sleep architecture. Ipamorelin and CJC-1295 raise GH, but their sleep effects remain untested in humans.
Methodology
Longevity peptides: weighing the evidence
Tesamorelin and ipamorelin get sold as anti-aging tools. Here is what the trial evidence actually supports, and the longevity gap it leaves.
