Copper-complexed tripeptide. Copper content verified by ICP on every lot.
3Why researchers study it
- Sequence-verified identity on every batch (ESI-MS)
- HPLC purity ≥98% required before a lot is listed
- Endotoxin (LAL) result published in EU/mL
- Batch code on the vial resolves to its own certificate
Certificates are dated and retained after a batch sells through. Absences are recorded, not papered over: if a test was not run, the COA says so.
4Batch & certificate
| Batch | Tested | HPLC | Endotoxin |
|---|---|---|---|
| SB-GHK-2604 | 2026-10-06 | 99.02% | <0.05 EU/mL |
* Certificates are per batch, dated, and retained in the library.
5Handling & storage
- Lyophilized powder ships ambient; short transit does not affect stability.
- Store desiccated at −20 °C long-term; 4 °C up to 3 months.
- Reconstitute with bacteriostatic water; swirl, do not vortex.
- Reconstituted solutions: 4 °C, typical 28-day window for bacteriostatic vehicles.

12Frequently asked
Does the COA match the batch I actually receive?
Yes. We do not publish one generic certificate per product. The batch code printed on your vial (SB-GHK-2604) resolves to that lot's own HPLC, MS and endotoxin results in the COA library, with the test date.
What purity is required before a lot can ship?
≥98% by HPLC at 220 nm plus confirmed identity by mass spectrometry. Lots failing either are rejected at intake and never listed.
How should it be stored and reconstituted?
Desiccated at −20 °C long-term, 4 °C up to 3 months. Reconstitute with bacteriostatic water and swirl — do not vortex. Reconstituted solutions keep at 4 °C, typically 28 days in a bacteriostatic vehicle.
Do you ship internationally?
US domestic only at launch, with select countries evaluated case by case. Checkout is authoritative for your address.
Do bulk tiers stack with promo codes?
Bulk tiers apply automatically at 5+/10+/20+ vials. Promo codes stack with tiers unless the code's terms say otherwise — the cart shows both lines before payment.
