KLOW is a multi-peptide research blend — GHK-Cu, BPC-157, TB-500 and KPV in a single 80 mg lyophilized vial. Third-party verified at 99.68% HPLC purity with every component quantified on the Certificate of Analysis, made in Canada and shipped domestically from British Columbia.

Section 01 — Definition
KLOW is a multi-peptide research blend — not a single compound, but four peptides combined in one lyophilized vial: GHK-Cu, BPC-157, TB-500 and KPV. It sits in the tissue-repair family of blends, and in the 80 mg format the copper peptide GHK-Cu is the dominant share.
The appeal of a blend is that each component is studied in a complementary repair or recovery model, so researchers investigating combined-peptide protocols reach for a single verified vial rather than mixing four separately. Because GHK-Cu is present, KLOW is a blue lyophilized powder — the colour of chelated copper.
Helix North supplies KLOW strictly as a lyophilized research material for in-vitro and laboratory use. Everything on this page is written for research handling and sourcing — it is not dosing guidance and not for human use.
Four repair peptides in one verified vial — KLOW is a combined-peptide research blend led by GHK-Cu.
Section 02 — Composition
KLOW's composition is itemized on its Certificate of Analysis, not left to guesswork. On the tested 80 mg lot, the four peptides were quantified individually — GHK-Cu the clear majority, with the other three in near-equal ~11 mg shares.
| Component peptide | Tested content |
|---|---|
| GHK-Cu (copper peptide) | 52.29 mg |
| TB-500 (thymosin β-4) | 11.29 mg |
| BPC-157 (body-protective) | 11.26 mg |
| KPV (α-MSH fragment) | 11.22 mg |
Each component brings its own research profile: GHK-Cu is the copper peptide studied in collagen and tissue-remodeling models; BPC-157 is the body-protective compound studied across connective-tissue and gut models; TB-500 is a thymosin β-4 fragment studied in actin-regulation and tissue-repair research; and KPV is an anti-inflammatory tripeptide fragment of α-MSH. Studied together, they make up KLOW's combined repair profile.
This is preclinical, mechanism-level research on the individual peptides; none of it constitutes evidence of a human therapeutic effect from the blend.
Section 03 — Verification
A blend is only as trustworthy as its Certificate of Analysis — because with four peptides in one vial, the only way to know what you have is a test that reports each one. KLOW's CoA does exactly that: an itemized per-peptide breakdown, not just a single blended purity figure.
The referenced lot tested at 99.68% purity by HPLC-UV, with a total peptide content of 86.03 mg against the 80 mg nominal fill — and each of the four component peptides quantified individually. The CoA, with lot number and chromatogram, is published on the product page so the composition can be verified before ordering. A searcher looking for the “KLOW certificate of analysis” will find it there.

Section 04 — Handling
KLOW ships as an 80 mg freeze-dried blend and is reconstituted with bacteriostatic water before use. As with any lyophilized peptide, the diluent volume sets the concentration — here of the combined four-peptide stock.
Wipe both stoppers with an alcohol prep pad, draw the chosen volume of bacteriostatic water into an insulin syringe, and add it slowly down the inside wall of the vial. Swirl gently until dissolved — never shake — then refrigerate at 2 to 8°C. An 80 mg vial reconstituted with 2 mL gives a 40 mg/mL combined-peptide stock. Expect a blue solution — that is the GHK-Cu copper going into solution, and it is normal for this blend.

Section 05 — Sourcing
Sourcing KLOW domestically removes the two problems that come with an offshore order: the customs wait and the currency markup. A Canadian-domestic shipment never crosses a border, so there is no customs hold and no risk of a package being detained or returned mid-protocol.
Helix North makes its peptides in Canada and ships from British Columbia by Canada Post Xpresspost — 1 to 2 business days on the West Coast, 2 to 4 for central Canada, a flat $30 to any postal code, tracked and in plain packaging. Pricing is in Canadian dollars. When the 80 mg blend is between production runs, its four component peptides — GHK-Cu, BPC-157, TB-500 and KPV — remain available individually.
The peptides in KLOW are legal to purchase and possess for research in Canada and are not controlled substances. KLOW is supplied strictly as a research material. New here? The Canadian research peptides overview covers testing and shipping across the whole catalog.
