Supplements, minus the hype.

Know what’s actually worth taking — honest, citation-backed reviews of legal collagen and peptide supplements, with clear guidance on what’s legal and what isn’t.

HOW WE SCORE

Supplements, minus the hype.

No sponsored placements and no pay-to-rank. Every product is scored on the same four criteria — and every health claim links to its citation.

Evidence base

Weight of human trials (RCTs), not brand marketing or anecdote.

Dose & form

Clinically studied dose, in a bioavailable, absorbable form.

Purity & testing

Third-party tested for contaminants and label accuracy.

Value

Real cost per effective serving — not just sticker price.

THE LEGAL LINE

Which peptides are legal — and which aren't

BPC-157 and TB-500 aren’t legal dietary supplements — they’re unapproved drugs. We cover them honestly, the science and the law, but we never sell them.
