Evidence at a glance

Human and animal counts are PubMed records from our evidence ledger (search counts, not studies we reviewed). The grade is the strongest design among the studies we summarised for that goal: a human randomized trial outweighs any number of animal studies. KLOW itself has not been studied; grades come from its ingredients' studies.

Grades follow our evidence scale. Summarised studies come from our evidence files for GHK-Cu, BPC-157, TB-500 and KPV, each quote checked against the abstract or label.

Common questions

Is KLOW FDA approved?

KLOW is Not FDA approved · unstudied blend. Products sold as research chemicals are not the approved drug and are not checked by the FDA.

What is in KLOW?

GHK-Cu, BPC-157, TB-500 and KPV, pre-mixed in one vial. Amounts per vial vary by seller and are rarely verified.

Is KLOW banned in sport?

Yes. Prohibited by WADA (S0), so it is prohibited at all times for tested athletes.

How much water goes in a 80 mg vial?

That choice only changes the concentration. With 2 mL, the vial is 40 mg/mL. The calculator converts any amount to syringe units. It does the math only and does not suggest a dose.
