Peptides.
Peptides are a drug class, not a single longevity strategy. Evidence ranges from an approved medicine for a narrow condition to compounds promoted online without controlled human efficacy or adequate product characterization.
6 evidence-ranked entriesWhat the evidence cannot settle yet
A hormone change, animal healing result, or benefit in a specific disease does not establish anti-aging, physique, or recovery benefits in healthy people. Combination products are especially difficult to assess when the mixture itself has never been tested.
Risks depend on the intervention
Endocrine effects, glucose changes, fluid retention, injection reactions, and unknown long-term risks require attention. Unapproved or compounded injections add sterility, identity, potency, impurity, and immunogenicity uncertainty.
Strong evidence leads this category
Ratings compare confidence in each entry's stated benefit—not whether every intervention is appropriate or recommended.
How ratings workEvery peptides entry
Sorted from stronger to weaker evidence.
Tesamorelin
An approved growth-hormone-releasing peptide that reduces visceral fat in HIV-associated lipodystrophy but is not a general weight-loss or anti-aging treatment.
Collagen Peptides
Oral hydrolyzed collagen may modestly improve skin hydration or elasticity, but study quality and industry funding temper confidence.
GHK-Cu
A copper-binding peptide with plausible skin and wound biology but sparse controlled human evidence and no established role for injectable anti-aging use.
BPC-157
An unapproved research peptide promoted for healing despite an evidence base dominated by animal studies and unresolved safety questions.
CJC-1295 + Ipamorelin
A marketed growth-hormone peptide stack with no controlled combination trial, ambiguous product identity, and major compounded-injection evidence gaps.
Human Growth Hormone
A prescription hormone with established replacement indications but an unfavorable benefit-risk profile for healthy-aging or physique use.
