About Klow Pen

Klow Pen is a blend of BPC-157, TB-500, GHK-Cu, and KPV, supplied as a prefilled, multi-dose injection pen. Combining them in one preparation means one injection instead of 4.

In published research, these compounds have been studied for tendon & ligament repair, gut healing, muscle recovery, soft-tissue recovery, and reduced inflammation. Research interest is not proof of benefit, and individual results vary.

A licensed provider is available to answer questions before you order.

What is in it

BPC-157

BPC-157 ("Body Protection Compound") is a 15-amino-acid peptide derived from a protein found in gastric juice. It is one of the most-studied peptides in tissue-repair research — tendon, ligament, muscle, and gut models — and the most common starting point for people new to peptide therapy.

Studied forTendon & ligament repair · Gut healing · Muscle recovery

How it works
Gastric pentadecapeptide; angiogenic and growth-factor signalling (VEGFR2, NO)

TB-500

TB-500 is a synthetic fragment of thymosin beta-4, a protein involved in cell migration and wound healing. It is studied for soft-tissue recovery and is frequently paired with BPC-157 — G1's Wolverine pen combines the two.

Studied forSoft-tissue recovery · Reduced inflammation · Wound healing

GHK-Cu

GHK-Cu is a naturally occurring copper-binding tripeptide whose levels decline with age. It is studied for collagen and elastin signalling, wound healing, and hair growth, and is the backbone of G1's GLOW and KLOW blends.

KPV

KPV (lysine-proline-valine) is the C-terminal tripeptide of alpha-melanocyte-stimulating hormone. It is studied for its effect on inflammatory signalling in the gut and skin, and appears in G1's KLOW pen alongside BPC-157, TB-500, and GHK-Cu.
