GHK-Cu + BPC-157
A two-peptide combination combining GHK-Cu's collagen and skin-repair effects with BPC-157's gastrointestinal and connective-tissue support. Often used during post-surgical recovery or in cosmetic protocols.
The GHK-Cu + BPC-157 stack combines 2 peptides — GHK-Cu and BPC-157. The reference reconstitution chart below shows each component's typical vial, BAC water, dose, and U-100 syringe units.
Per-component reference presets — when supplied as a single multi-peptide vial, follow your compounder's label. Adjust the calculator below for your vial.

How to use this calculator›
- 1. Vial — the peptide amount printed on the vial, in milligrams.
- 2. BAC water — the bacteriostatic water added to the vial. More water means a lower concentration and a larger, easier-to-read draw.
- 3. Dose — the single dose being measured, in milligrams.
- 4. Syringe — the barrel being drawn into. The diagram rescales to that syringe, so the same dose sits at a different mark on a 0.3 mL barrel than on a U-100.

Why these peptides together
GHK-Cu and BPC-157 act on distinct pathways — GHK-Cu via copper-mediated collagen synthesis and BPC-157 via growth-factor and nitric-oxide signalling — so the combination is rationalised on additive rather than overlapping mechanisms.
Where researchers source this
Vendors below have been manually vetted for third-party COA practice and shipping reliability. Verify the current Certificate of Analysis on the vendor's product page before purchase.
Ascension PeptidesUSA-based research vendor (Castle Rock, Colorado) publishing a per-batch Certificate of Analysis library with public lot IDs, so a vial can be matched to its own COA before and after purchase. Recent HPLC purity 99.79–99.98% across the catalog. Ships from the US and carries the full GLP-1 reference range alongside repair, longevity and cosmetic compounds.

How it's typically run
Reconstitute each peptide separately and either co-draw or alternate injection sites. Typical doses: GHK-Cu 1–3 mg subcutaneous, BPC-157 250–500 µg one to three times daily.
Frequently asked questions
- Can these be mixed in the same syringe?
- Yes, many users co-draw both peptides into a single insulin syringe at the time of injection. Reconstitute separately to keep concentrations independent.
