Klow dosage calculator
Klow peptide blend calculator for the pre-blended BPC-157 + GHK-Cu + KPV formulation. Reference 10mL vial with 3mg / 30mg / 3mg component ratios. Per-component dose math and live U-100 insulin syringe draw.
How to use this Klow blend calculator
Klow is a pre-blended peptide formulation combining BPC-157 + GHK-Cu + KPV in a single lyophilized vial — a "stack-in-a-vial" designed to cover tissue repair (BPC-157), copper-mediated healing and skin/hair support (GHK-Cu), and anti-inflammatory signaling (KPV) in a single injection. This calculator models the most common reference formulation (3mg BPC-157 + 30mg GHK-Cu + 3mg KPV per 10mL reconstituted vial, totaling 36mg of total peptide). Because Klow formulations vary by supplier, the calculator's result is a reference — always check your specific vial's label for exact per-peptide ratios.
What's in a Klow vial
The reference Klow formulation contains three peptides at fixed ratios per 10mL reconstituted vial: 3mg BPC-157 (tissue repair, angiogenesis, gut healing), 30mg GHK-Cu (copper tripeptide — wound healing, skin, hair, collagen synthesis), and 3mg KPV (α-MSH anti-inflammatory tripeptide). Total peptide per vial: 36mg. Each 1mL draw from a reconstituted 10mL vial delivers approximately 300mcg BPC-157 + 3mg GHK-Cu + 300mcg KPV — ratios that match effective daily doses of each component.
Klow reconstitution
Klow ships lyophilized in a single vial. Reconstitute with 10mL of bacteriostatic water (the standard supplier-recommended volume for the reference formulation). The 10mL volume yields clean per-draw delivery of therapeutic doses of all three component peptides at 1mL per injection. Smaller BAC volumes (5mL) are possible for users wanting smaller draws, but the 10mL standard is what most supplier dosing guidance assumes.
Klow dose — typically 1mL per injection
Klow is dosed by injection volume (mL), not by a single peptide's mg. The standard dose from a reference Klow vial is 1mL per injection, which delivers the full effective daily doses of BPC-157 (300mcg), GHK-Cu (3mg), and KPV (300mcg) in a single subcutaneous draw. Enter 1mL as your target dose above — or adjust for your specific supplier's formulation and preferred component doses.
Read the U-100 syringe units
Pull the plunger to the indicated unit mark on a 1mL U-100 insulin syringe. A 1mL Klow draw fills the entire U-100 syringe (100 units) — the full barrel. If you want a smaller draw (e.g., 0.5mL for a lower-dose day, or to extend the vial), draw to 50 units on a U-100 syringe. The visual syringe shows the fill in real time.

Klow peptide blend — composition, dosing, and reconstitution guide
Klow is a pre-blended research peptide formulation combining BPC-157, GHK-Cu, and KPV in a single vial. The blend emerged from the broader research-peptide community's practice of stacking these three compounds for combined tissue-repair + anti-inflammatory + copper-peptide effects, and has been formalized into pre-mixed vials by multiple research suppliers. "Klow" is a community name (derived as a rhyme/variant of the older "Glow" blends focused on skin and hair), not a pharmaceutical brand. This guide covers Klow composition and the reference formulation, reconstitution math, per-component dosing breakdown, the rationale for the three-peptide combination, the Klow vs Glow distinction, supplier formulation variance, cycle length, and side effects.
Klow composition — BPC-157 + GHK-Cu + KPV
The three components target complementary biological axes. BPC-157 (Body Protection Compound) is a 15-amino-acid peptide derived from a gastric protein fragment — the primary tissue-repair and angiogenesis driver. GHK-Cu (copper tripeptide) is a glycyl-histidyl-lysine tripeptide bound to copper(II) — the primary skin, hair, wound-healing, and collagen-synthesis agent, distinctive for its characteristic blue color in solution. KPV is the lysine-proline-valine tripeptide fragment of α-MSH — the primary anti-inflammatory signaling component, acting via NF-κB pathway suppression. The blend captures all three mechanisms in a single injection.
| Component | Per reference 10mL vial | Per 1mL draw | Function |
|---|---|---|---|
| BPC-157 | 3 mg | 300 mcg | Tissue repair, angiogenesis, gut healing |
| GHK-Cu | 30 mg | 3 mg | Wound healing, skin, hair, collagen synthesis |
| KPV | 3 mg | 300 mcg | Anti-inflammatory (α-MSH fragment) |
| Total peptide | 36 mg | 3.6 mg | Combined dose per 1mL injection |
Klow reconstitution
Klow reconstitutes with bacteriostatic water in a single step despite containing three different peptides. All three components are stable in BAC water at refrigerated temperatures for similar durations (~4 weeks), so the blend behaves as a single reconstituted solution after mixing. The GHK-Cu component gives the reconstituted Klow its characteristic pale blue tint — visible color is a quick visual confirmation that the GHK-Cu is intact and has not degraded.
Klow dosing per component
A 1mL subQ injection from a reference Klow vial delivers: BPC-157 at 300mcg (a mid-range daily dose — common solo BPC-157 protocols use 250–500mcg daily), GHK-Cu at 3mg (a standard solo GHK-Cu daily dose — solo protocols use 1–2mg subQ daily, so a Klow dose is slightly above standard), and KPV at 300mcg (a lower daily dose than common solo KPV research, which uses 500–1000mcg daily). The blend ratios reflect a design emphasis on GHK-Cu as the dominant component — the blend's identity is skin/hair/wound-healing support with BPC-157 and KPV as the tissue-repair and anti-inflammatory supporting cast. Users wanting higher KPV or BPC-157 exposure sometimes supplement with solo vials of those peptides alongside Klow.
Klow vs Glow vs stacking individually
"Glow" is the older community name for blended skin/hair-focused peptide formulations, often containing GHK-Cu + BPC-157 without KPV (or with different third components). Klow specifically refers to blends including KPV as the third component for added anti-inflammatory signaling. The naming is community convention, not pharmaceutical standard — different suppliers use "Klow" to refer to slightly different formulations. Stacking individually (injecting solo vials of BPC-157, GHK-Cu, and KPV separately) gives precise per-component dose control but requires three vials, three reconstitutions, and three injections (or combining draws into one syringe at mix-time). Klow trades dose-tuning flexibility for convenience — one vial, one reconstitution, one weekly or daily injection.
Klow cycle length
Klow cycles typically run 4–8 weeks of daily subQ dosing followed by a 2–4 week break. The cycle length is bounded by the BPC-157 and GHK-Cu components (the KPV component has no documented tolerance and could run continuously). Wound-healing or acute-injury protocols run shorter (2–4 weeks). Skin/hair research protocols run longer (6–8 weeks) given the slow tissue turnover timeline. Cycles can be repeated after breaks; the GHK-Cu and KPV components have no documented receptor desensitization, and BPC-157 tolerance is minimal.
Klow side effects
Klow's side-effect profile is the combined profile of its three components, which is generally well-tolerated. Injection-site reactions (mild redness, brief stinging) are the most common observation — primarily from the GHK-Cu copper component, which can sting slightly on subQ injection. Transient injection-site staining (pale blue tint) is possible from the GHK-Cu color. No systemic side effects are reported at standard 1mL daily doses. Klow does not produce the pigmentary or appetite effects of full α-MSH because the blend uses the KPV fragment, which lacks those activities. Users with copper sensitivity or Wilson's disease should not use Klow (or any GHK-Cu-containing blend).
Supplier formulation variance
"Klow" is a community formulation category, not a standardized pharmaceutical product, so supplier-to-supplier composition varies. Common variations: different component ratios (some suppliers use 5mg BPC + 50mg GHK-Cu + 5mg KPV per 10mL instead of 3/30/3), different total blend sizes (10mL reference vs 5mL concentrated), occasional fourth components (TB-500, thymosin-α-1, or others). Always verify your specific vial's label for exact per-peptide mg content and manufacturer-specified reconstitution volume.
