Peptide stack
BPC-157 + TB-500 + GHK-Cu + KPV
The full recovery stack plus an anti-inflammatory tripeptide.
Also known as: KLOW stack
Components studied separately, not the combination
COMPONENTS in this stack
-
BPC-157
A 15-amino-acid fragment of the gastric body-protection compound, the most widely self-administered healing peptide for tendon, ligament, muscle, and gut injuries.
Research chemical -
TB-500 / Thymosin Beta-4
A naturally occurring wound-response peptide released by platelets, used for muscle, tendon and neurological healing, often stacked with BPC-157.
Research chemical -
GHK-Cu
A naturally occurring copper-binding tripeptide found in human plasma. The best-studied skin peptide, also investigated for wound healing, hair and connective tissue.
Cosmetic (topical) / off-label injectable -
KPV
A tiny 3-amino-acid fragment of alpha-MSH studied mainly for gut and skin inflammation, popular among self-experimenters with IBD-type symptoms.
Research chemical
Why these are combined
Adds KPV, an alpha-MSH-derived tripeptide that suppresses IL-1beta, IL-6 and TNF-alpha, to the base three-peptide recovery stack. The idea is to calm inflammation while the other three drive repair. Nobody has tested all four together.
Mechanism & pharmacokinetics
KPV adds a fourth, again mechanistically distinct pathway: it's an alpha-MSH-derived tripeptide that works through melanocortin-receptor signaling and direct suppression of NF-kB-driven cytokine production (IL-1beta, IL-6, TNF-alpha), independent of the growth-factor, actin, and collagen-remodeling pathways the other three use. Like BPC-157 and GHK-Cu, KPV clears from plasma quickly and is dosed frequently in community protocols. The name 'KLOW' is generally explained in community sources as 'K(PV) + (G)LOW' — the GLOW stack with KPV added, rather than a literal per-letter acronym of all four ingredients. Combining four unstudied-together compounds compounds the uncertainty rather than resolving it: there is no data on the four-way combination, only individual-peptide and at-most-three-peptide reasoning stacked on top of each other.

Typical community protocol
BPC-157 250-500 mcg daily, TB-500 2-4 mg weekly, GHK-Cu 200-300 mcg daily, KPV 100-300 mcg daily (occasionally intranasal). Often run 8-16 weeks for injury or post-surgical recovery.
Safety notes
Community notes (anecdotal — not clinical evidence)
An 'all-in' extension of the base stack in advanced recovery circles. Driven by mechanistic appeal, not evidence.
