Supported

None of the five claims about this peptide cream product are supported by direct scientific evidence from PubMed or registered clinical trials. While PeptIQ's internal knowledge base includes collagen peptides profiles and articles on peptide mechanisms (e.g., GHK-Cu, BPC-157 for other conditions), the specific claims about skin regeneration, elasticity, wrinkle reduction, smoothness, and plumping lack corresponding peer-reviewed studies or human trials. The retrieved clinical trials address unrelated conditions (stem cell transplantation, acupuncture, botulinum toxin). Without cited studies, mechanism documentation, or relevant trial data, these claims cannot be evaluated as scientifically supported.

Claim breakdown

5 claims
1

Peptides activate skin regeneration.

Supported

No PubMed studies or directly relevant clinical trials were identified that specifically examine peptides and skin regeneration. The trials retrieved (stem cell transplantation, acupuncture, neonatal darbe) do not address topical or systemic peptide effects on skin regeneration.

2

Peptides increase skin elasticity.

Supported

No PubMed studies or directly relevant clinical trials were identified that specifically examine peptides and skin elasticity. Of the three trials retrieved, only NCT03771807 (nutritional supplement on skin health, completed) is conceptually adjacent, but no abstract or results were provided to confirm peptide involvement or elasticity outcomes.
