Klow (GHK-Cu / BPC-157 / TB-500 / KPV)
Also known as: KLOW, Glow + KPV, GHK-Cu/BPC-157/TB-500/KPV blend
Klow (often written KLOW) is a marketing name for the Glow blend, GHK-Cu, BPC-157, and TB-500, with a fourth peptide, KPV, added. KPV is a short fragment studied for anti-inflammatory effects, so Klow is marketed as Glow with an added anti-inflammatory component. It is not a single drug or an FDA-approved product; it is a four-peptide combination that licensed compounding pharmacies prepare and telehealth clinics prescribe.
What's in this blend
Klow combines the following peptides. The blend's effects and risks are those of its components together; open each for its own evidence and safety.
- GHK-Cu (Copper Tripeptide-1)A copper-bound tripeptide studied for wound healing and skin support, used mainly as a topical cosmetic ingredient and not approved as a drug.
- BPC-157BPC-157 is a synthetic peptide studied in animals for tissue repair. It is not FDA-approved and remains investigational in humans.
- TB-500A synthetic peptide related to thymosin beta-4, studied in animal models for tissue repair and not approved for human use.
- KPVKPV is an investigational tripeptide fragment of alpha-MSH studied in preclinical models for its anti-inflammatory properties.
How it works
The GHK-Cu, BPC-157, and TB-500 components carry the same proposed skin- and repair-related mechanisms described for the Glow blend. KPV is a tripeptide derived from the hormone alpha-MSH that has been studied in laboratory and animal models for calming inflammatory signaling, including in the gut. The four-peptide Klow combination has not been evaluated as a single product in controlled human trials.
Researched uses
- Marketed for skin, hair, and recovery (the Glow components)
- Marketed for inflammation and gut support (the KPV component, based on laboratory and animal data)
- Used for combined cosmetic, recovery, and anti-inflammatory goals, though the four-peptide blend is unproven in humans
There is no FDA-approved Klow product. GHK-Cu is a cosmetic ingredient rather than an approved drug, BPC-157 remains under regulatory review and is not on the FDA compounding bulk list, and TB-500 and KPV are sold as research chemicals and are not established compounding substances. Providers listed here dispense with a prescription and describe a licensed pharmacy, but because these four peptides sit outside the settled compounding rules the legal pathway is not clear-cut, so review each provider's own sourcing. BPC-157 and TB-500 appear on the WADA Prohibited List; GHK-Cu and KPV are not specifically listed.

We average every cost to a standard 3-month protocol, which our medical advisors consider the best window for comparing cost and value. Monthly plans are multiplied by 3 and 3-month programs are taken as billed; each provider's own sticker price and cadence are shown underneath.
The headline figure is the total 3-month cost: the medication plus any one-time consult or provider-review fee (for example RxPepsDirect's $39) and three months of any membership fee. Where a fee is not published we fold in what is known and flag that other fees may apply.
Per-vial providers are averaged to a 3-month protocol at roughly one vial per month (3 vials), marked "est.", with the per-vial price shown underneath. Actual vial count depends on your dose and protocol.
Prices are gathered from each provider's public pages. The "Verified" date is when we last checked the provider's sticker price; for per-vial providers it is the vial price that was verified, not the averaged 3-month total.
Value check: total cost of therapy
This is the real value comparison. A sticker price hides consult and membership fees, so this adds everything up for a full protocol of Klow (GHK-Cu / BPC-157 / TB-500 / KPV) and ranks by true total cost. We default to a 3-month protocol, the window our medical advisors consider best for judging value.
Per-vial providers are estimated at about one vial per month (3 vials for 3 months), plus any one-time consult. Actual vial count depends on your dose and protocol, so the real cost may run higher or lower.
Safety notes
The safety of the Klow blend has not been established in humans. It combines four investigational peptides, so the uncertainty is greater than for any single component, and there are no controlled human trials of the combination. Composition varies between providers. Products sold outside the licensed pharmacy system are not verified for identity, purity, or sterility.
