For Research Use OnlyKlow – 80mg
Klow is a four-component preparation containing GHK-Cu 50mg, TB-500 10mg, BPC-157 10mg and KPV 10mg, totalling 80mg. Purchased individually at matching vial sizes those four cost $230, against $125 here. Blend names are conventions rather than standards, so quantities published elsewhere frequently describe well under half this total; take figures from the product record rather than a general article. Because proportion is the specification for a blend, a certificate must report quantity per component and reconcile to 80mg, not merely confirm four components are present and pure. Ratios are fixed at manufacture and reconstitution scales all four together. Research use only.
