KLOW Blend extends the GLOW composition with a fourth component: 50 mg GHK-Cu, 10 mg TB-500, 10 mg BPC-157 and 10 mg KPV, for 80 mg total.
KLOW Blend extends the GLOW composition with a fourth component: 50 mg GHK-Cu, 10 mg TB-500, 10 mg BPC-157 and 10 mg KPV, for 80 mg total.
It is the most complex preparation in the catalogue. Per-lot laboratory certificates for the four constituents and for the post-blend assay are not yet available; PeptideSeed is working with its supplier to obtain genuine documentation for this blend lot number.
As with GLOW, the copper content governs handling. Keep the vial in its opaque secondary packaging and protect reconstituted solution from light.

Vials arrive lyophilized and sealed under nitrogen. Bring the vial fully to room temperature before breaking the seal — opening a cold vial condenses atmospheric moisture onto the cake.
Direct diluent gently against the inside wall of the vial rather than onto the cake, and allow the material to dissolve without agitation. Vortexing shears longer sequences and introduces air.
Lyophilized: -20 C, protected from light. Reconstituted: 2-8 C, use within 30 days.
A full walkthrough is in the reconstitution guide, and the calculator will work out concentration and draw volume for this vial size.
Standard laboratory practice applies: appropriate personal protective equipment, no consumption, no administration to humans or animals, and disposal in accordance with institutional protocol and local regulation.
Per-lot laboratory certificate: pending. A reverse-phase HPLC purity report, an LAL bacterial endotoxin assay and a mass-spec identity confirmation for lot PS-8021447 have not been generated or published. PeptideSeed is working directly with its supplier to obtain genuine per-lot documentation and will publish it here, tied to this exact lot number, once it exists. New to reading these?

50 mg GHK-Cu, 10 mg TB-500, 10 mg BPC-157, 10 mg KPV - 80 mg total.
KLOW adds 10 mg of KPV to the GLOW composition, taking the vial from 70 mg to 80 mg.
Five are planned - four component assays plus the post-blend assay - but none are yet available for this lot. Check the lab reports page for current status.
KLOW Blend is supplied for in-vitro laboratory research only. It is not a drug, dietary supplement, food or cosmetic, is not approved by the FDA for any use in humans or animals, and no dosing guidance is published for it. Nothing on this page is a therapeutic, structure–function or health claim. Purchasers must be 21 or over and are responsible for compliance with all applicable law. Full terms of supply.
