What did @diego_chamorro3 actually say?
Honestly? Very little that's coherent. The transcript here is nearly impossible to evaluate on scientific grounds because the audio-to-text capture has produced something largely incoherent, cycling through phrases like "the art of art" and "I will show you a link in the description" repeatedly. The creator tags GHK-Cu in the hashtags and promotes a discount code for @axionyx.lab, but the transcript doesn't contain a single verifiable scientific claim about the peptide.
This matters. When a creator promotes a supplement brand with a discount code, the content becomes commercial speech, not just personal expression. The caption claims the content is "based on scientific evidence," but the transcript offers no evidence of that. No mechanism. No study. No dosing rationale. Just a broken monologue and a discount code.
Does the science back this up?
There's no specific claim here to evaluate against the science, which is itself a problem. But since the video tags GHK-Cu, it's worth laying out what the research actually shows, so viewers know where the real lines are.
GHK-Cu (copper peptide GHK) has legitimate research behind it, mostly in dermatology and wound healing. Pickart and Margolina (2018, Biomedicines) summarized evidence showing GHK-Cu promotes collagen synthesis, has antioxidant properties, and may support wound repair in topical applications. Finkley et al. (1999, Skin Pharmacology and Physiology) found topical GHK-Cu improved skin laxity in a small controlled trial. That's real data. However, systemic injection of GHK-Cu in humans is a different story: clinical trial evidence is thin, regulatory approval is absent, and compounded injectable versions sold outside a physician-supervised protocol exist in a legal gray zone.
What did they get wrong (or right)?
What they got wrong: promoting a commercial peptide product while claiming scientific backing, without actually presenting any science. The phrase "based on scientific evidence" in the caption is doing a lot of heavy lifting over an empty transcript. That's not evidence-based content. That's a label slapped on a sales pitch.
What they might deserve partial credit for: not making outrageous cure claims in the transcript, though that's mostly because no intelligible claims were made at all. The hashtag use of "ghkcu" and "pielsanapielbella" (healthy skin) is at least narrower than, say, claiming a peptide reverses aging or cures a disease. But the combination of a discount code, a vague scientific authority claim, and zero actual explanation is a pattern that should make any viewer skeptical.
What should you actually know?
GHK-Cu is one of the more researched peptides in the cosmetic and wound-healing space, but the evidence is not uniform across applications. Topical use has more published support than injectable use. Pickart (2008, Journal of Biomaterials Science) described GHK-Cu as a signaling molecule that activates tissue remodeling genes, but translating that to consumer injectable peptides is a significant leap not yet validated in large human trials.
Any peptide sold with a discount code on Instagram, without a licensed prescriber involved, is not being sold in a regulated medical context. Compounded peptides vary in purity, concentration, and sterility depending on the compounding pharmacy. Buyers should ask for a certificate of analysis, confirm the compounder is an FDA-registered facility, and involve a physician before using any injectable peptide. "Based on scientific evidence" is not a safety guarantee. It's a marketing phrase.
