Trial floors

Primary

Verisol skin trials (branded peptide) · 2.5 g over 8 weeks (medium evidence · how we grade this) · Benefit shown — Specific bioactive peptide preparation — generic 20 g powder is not equivalent evidence.

Secondary

Generic hydrolyzed collagen (instrumental skin trials) · 2.5–10 g (limited evidence · how we grade this) · Benefit shown — Pooled human skin trials often land in 2.5–10 g/day depending on preparation and endpoint.

Label reading notes

  • Human skin trials used specific peptide preparations (often branded, e.g. Verisol) at 2.5–10 g/day. Generic "hydrolyzed collagen" or "collagen peptides" at the same gram count does not inherit those endpoints.
  • Collagen marketing for Ozempic face is not evidence for surplus skin after rapid weight loss. No published RCT tests oral peptides for post–weight-loss skin laxity or facial volume.
  • Branded peptide vs generic powder matters for claim matching. A beauty blend with collagen as the fourth ingredient rarely delivers a studied daily total in one serving.
  • Gummies and flavored sticks often trade dose for sugar and acids; check grams of active collagen per day, not "one gummy."
