Six things worth checking on any research-chemical order, and what you get here versus what the category typically does.
Provyd
Aluminium crimp seal intact and unbroken, stopper embossed. A seal that arrives compromised is grounds for replacement.
Typical research-chemical vendor
Loose or re-crimped caps are common, with no stated policy if the seal arrives broken.
Describes common practices in the research-chemical category, not any specific company. Provyd performs no independent or third-party testing, and all documentation referenced is supplied by the manufacturer.

State of the evidence
Predominantly in-vitro and animal data; one small randomized human trial in laser-resurfaced skin found no significant objective benefit. No large human efficacy trials identified.

Effects of topical copper tripeptide complex on CO2 laser-resurfaced skin
Miller TR, et al.
In 13 patients following CO2 laser resurfacing, topical GHK-Cu reported no statistically significant difference versus control in erythema resolution, wrinkles or objectively assessed skin quality, though patient-reported overall skin quality favoured GHK-Cu (P = .04).
- Animal preclinicalJournal of Clinical Investigation · 1993
In vivo stimulation of connective tissue accumulation by the tripeptide-copper complex glycyl-L-histidyl-L-lysine-Cu2+ in rat experimental wounds
Maquart FX, et al.
In a rat subcutaneous wound-chamber model, GHK-Cu injection produced a concentration-dependent increase in chamber dry weight, DNA, total protein, collagen and glycosaminoglycan content versus saline controls.
- In vitroJournal of Peptide Science · 2012
Stem cell recovering effect of copper-free GHK in skin
Choi HR, et al.
In cultured normal human keratinocytes and skin-equivalent models, copper-free GHK increased keratinocyte proliferation and significantly increased the number of p63- and PCNA-positive basal cells versus untreated controls.

GHK Peptide as a Natural Modulator of Multiple Cellular Pathways in Skin Regeneration
Pickart L, et al.
This review summarised in-vitro and animal evidence that the GHK tripeptide modulates collagen and glycosaminoglycan synthesis, antioxidant pathways and gene expression relevant to skin remodelling, and noted the absence of large controlled human trials.
