Glow Blend

Rows are ordered by price per mg: listed price divided by stated peptide content, excluding shipping and codes, so every vial competes on the same axis. Each row carries its own $/mg figure, so the size of the gap between vendors is visible, not just the order. Sprays follow the vials, unranked.

The best-documented testing flag goes to the vendor publishing batch-level, third-party certificates. The shipping flag goes to the fastest published delivery from a domestic warehouse. Data is re-checked on a schedule and each row carries its verification date.

Tri-peptide skin & tissue-senescence-marker research stack — BPC-157 + TB-500 + GHK-Cu in one vial.

GHK-Cu is a naturally occurring copper-binding tripeptide. GHK-Cu is a naturally occurring copper-binding tripeptide that regulates over 4,000 genes involved in peptide research, collagen synthesis, and anti-inflammatory responses. 2025-2026 research confirms it delivers bioavailable copper, resets cellular gene expression to a younger-marker state, reduces IL-6/TNF-alpha, supports DNA repair via 84 anti-cancer-related genes, and shows cumulative collagen remodeling with 3-6 months of use. It has a molecular formula C14H24N6O4Cu (copper complex), mass 340.38 Da (free peptide) / 401.93 Da (copper complex) Da. Its published amino-acid sequence is Gly-His-Lys. Common synonyms in the literature include Copper Peptide GHK, GHK Copper, and Glycyl-L-histidyl-L-lysine copper. This SKU is a co-formulated blend that also contains TB-500 (Thymosin Beta-4 Fragment) in the same vial — for research groups that want to combine the two under a single reconstitution.

Investigation of GHK-Cu to date is clinical-investigational, with the majority of citations concentrated in animal models and in-vitro assays rather than randomized controlled human trials. Published work referencing GHK-Cu spans Topical wound healing: Extensive research has examined GHK-Cu in dermal wound models, showing effects on reepithelialization, collagen deposition, and wound closure. GHK-Cu superiority over GHK alone has been demonstrated in murine wounds, with effects requiring Cu²⁺ (abolished by chelators like bathocuproine), Skin aging and cosmetic research: Studies have investigated GHK-Cu for effects on photoaging, dermal collagen research, skin thickness, and elasticity. Most human data comes from cosmetic product studies rather than rigorous clinical trials, and Gene expression studies: Microarray analyses have shown GHK-Cu modulates expression of over 4,000 genes, with structural genes upregulated and inflammatory/damaging genes downregulated. Key affected pathways include TGF-β signaling, DNA repair, and antioxidant systems. Proposed mechanisms in the literature include Copper delivery: forms stable complex with Cu²⁺ (binding constant log10 ≈ 16.44), delivering copper while silencing redox toxicity and Gene expression: upregulates structural genes (TGF-β pathway) and downregulates inflammatory genes (IL-6, fibrinogen). None of this material describes therapeutic outcomes in humans, and No vendor listed here provides dosing guidance for GHK-Cu outside laboratory research.
