About GHK-Cu (Copper Peptide) 100 mg
Buy GHK-Cu 100mg at IGF1 Shop — the bulk dose of our copper tripeptide. Same pure compound as our 50mg vial (Glycyl-L-Histidyl-L-Lysine bound to Cu²⁺, CAS 130120-56-8) at ≥99% HPLC purity, but in a 100mg fill that delivers the lowest cost per milligram for users running longer protocols or compounding their own topical serums. Each GHK-Cu 100mg vial is ESI-MS verified, LAL endotoxin tested below 0.5 EU/mg, and shipped with a per-lot Certificate of Analysis from an ISO 17025-accredited lab.

GHK-Cu (Copper Peptide) 100 mg — Mechanism & Specifications
Identical compound to the 50 mg vial — Glycyl-L-Histidyl-L-Lysine bound to Cu²⁺ — provided in a doubled dose for users requiring extended supply or higher single-dose preparations.
Quality & release criteria
Every lot of GHK-Cu (Copper Peptide) 100 mg is released only after passing reverse-phase HPLC (≥ 99% area purity at 220 nm against a reference standard), ESI mass spectrometry confirmation of molecular weight, and Limulus Amebocyte Lysate (LAL) endotoxin testing below 0.5 EU/mg. The lot-specific Certificate of Analysis is provided with the order and available on request before purchase.

FAQ
GHK-Cu (Copper Peptide) 100 mg — Frequently asked questions
Why buy GHK-Cu 100mg vs 50mg?
The GHK-Cu 100mg vial gives the lowest cost per milligram in our lineup and is the right pick for longer cycles, dual-route protocols (split topical + subcutaneous), or DIY serum compounding where you need bulk active. Same compound, same ≥99% HPLC purity, same per-lot COA — just twice the mass per vial.
How long does a 100mg vial last?
At a 1mg/day subcutaneous reference protocol, GHK-Cu 100mg covers ~100 days of dosing. At 2mg/day, ~50 days. For topical compounding, 100mg in a 10mL base yields a 1% serum — about a 1-2 month supply at typical scalp/face coverage.
What's the reconstitution math for 100mg?
Add 5mL of bacteriostatic water to the GHK-Cu 100mg vial. Each 0.1mL then contains 2mg of GHK-Cu. For lower-dose protocols, add 10mL — each 0.1mL contains 1mg. The vial is overfilled slightly to account for needle dead-space; the printed mass is the minimum guaranteed peptide content.
Is the 100mg vial third-party tested per lot?
Yes. Every lot, both 50mg and 100mg, runs through the same ISO 17025-accredited test suite: HPLC ≥99%, ESI-MS molecular identity confirmation, LAL endotoxin <0.5 EU/mg, and sterility. The COA references the specific batch number printed on the vial.
Can I split a 100mg vial?
The dry powder can be aliquoted with a clean spatula in a low-humidity environment if you have the lab capability. Easier and safer: reconstitute the full GHK-Cu vial and aliquot the solution into sterile vials, store frozen, and thaw as needed. Reconstituted GHK-Cu loses some potency past 30 days refrigerated, so plan accordingly.
Does GHK-Cu interact with other peptides?
There are no widely documented interactions between GHK-Cu and BPC-157, TB-500, or KPV — which is why blends like GLOW (70mg) and KLOW (80mg) exist. If you're already using systemic copper supplementation, account for that in your total intake. We do not recommend mixing GHK-Cu with peptides containing reactive cysteine residues at high concentrations.
How is the 100mg vial shipped internationally?
GHK-Cu 100mg ships in discreet, plain, unbranded outer packaging — no peptide-related markings. Cold-chain insulation is included for international transit. Tracked shipping is standard worldwide. Orders above $59 ship free.
