The per-mg and multi-vial math is broken down on the KLOW price per vial page, and the complete KLOW guide covers what each of the four peptides has been studied for. The reconstitution calculator does the arithmetic for mixing the vial with bacteriostatic water and reports it in units rather than mL.

Before you buy

What should you check before you buy KLOW?

Check that the certificate confirms identity for each of the four peptides, not once for the vial. A single identity line on a four-peptide vial has not tested four peptides. The released batch, lot KLW-260412-A, shows identity by HPLC + LC-MS (per component), 98.60% purity by HPLC, and 80.90 mg of net peptide against the 80mg on the label.

  • Four components, four results. The certificate should list the content of each component (this batch reads 10 + 50 + 10 + 10 mg) and confirm each one by mass spectrometry.
  • The rest of the panel. Titreon Analytical's certificate also reports sterility, bacterial endotoxin, heavy metals and a fentanyl screen for the batch.
  • No borrowed trial. Each of the four peptides has its own research record, and the blend has none. A seller claiming trial evidence for the combination is claiming something that does not exist.
  • Your own batch. Vials ship unlabeled on purpose, so verification runs on your order number. Message us on WhatsApp with it and we will confirm your batch and send its published certificate.

The checks that apply to any seller are in how to verify peptide purity, and the full certificate for this batch is on the KLOW certificate card.

The short answer

What is the KLOW peptide blend?

KLOW is a four-peptide research blend in one 80mg vial: BPC-157, TB-500, GHK-Cu and KPV. Each is drawn from a separate repair literature: BPC-157 for gut and tendon endpoints (Sikiric et al., 2020), TB-500 (thymosin beta-4) for wound healing and soft-tissue migration (Malinda et al., 1999), GHK-Cu for skin renewal and collagen (Pickart et al., 2018; Maquart et al., 1988), and KPV for anti-inflammatory signaling. The point of the blend is coverage from a single vial rather than three or four separate reconstitutions. No published trial has measured these four peptides together, so every figure here describes one component in isolation, and any dose is a decision for a licensed clinician, not a number this page sets for you.

The Blend

Four Peptides, Four Angles of Repair

KLOW combines four well-studied repair peptides in one vial. Each covers a different part of recovery, so one vial covers the tissue, gut and skin research areas at once.

BPC-157

Gut lining and tendon-ligament repair, with a strong research history.

TB-500

Studied for systemic soft-tissue and muscle repair endpoints, largely in animal models.

GHK-Cu

Copper peptide for skin renewal, collagen, and wound healing.

KPV

A short anti-inflammatory peptide that complements the repair components.

Applications

Common Use Cases

Whole-Body Recovery

When tissue, gut, and skin all need support at once.

Simplified Protocol

One injection instead of managing three or four separate vials.

Post-Injury Repair

Tissue-repair and anti-inflammatory signaling are the studied research areas for these components.

Gut Plus Skin

BPC-157 and GHK-Cu together for digestive and dermal repair.

Blend vs singles

KLOW blend vs BPC-157, TB-500 and GHK-Cu bought separately

The most common question about a blend like KLOW is whether it beats running the single peptides. The honest answer is that it is a packaging and convenience decision, not a pharmacological upgrade: KLOW puts a fixed ratio of BPC-157, TB-500, GHK-Cu and KPV into one 80mg vial, so one reconstitution covers all four instead of three or four. What a blend cannot do is inherit a trial. The BPC-157, TB-500 and GHK-Cu records are each their own literature (Sikiric et al., 2020; Malinda et al., 1999; Pickart et al., 2018), and none of them studied this combination.

ApproachWhat it isBest when
KLOW blendBPC-157 + TB-500 + GHK-Cu + KPV in one 80mg vial, fixed ratioOne vial and one reconstitution for broad tissue, gut and skin coverage
Single peptidesSeparate BPC-157, TB-500 and GHK-Cu vials, each dosed on its ownA single research target, or control over the ratio of each peptide
BPC-157 + TB-500 stackThe two soft-tissue repair peptides run together, without GHK-Cu or KPVInjury-recovery focus rather than skin and collagen

If your interest is one target, a solo vial is usually the cheaper route; the BPC-157 and TB-500 stack is the narrower two-peptide version of the same repair idea. Peptara Labs does not design combinations or adjust ratios for anyone.

Dosage, as studied

What doses did the studies use, and is there a KLOW blend dose?

There is no studied dose for the KLOW blend, because no trial has ever administered these four peptides together. What exists is the separate record for each component, and for BPC-157 and TB-500 that record is dominated by animal models rather than human dosing (Sikiric et al., 2020; Malinda et al., 1999). GHK-Cu's strongest human evidence is topical, from skin studies rather than injectable protocols (Pickart et al., 2018; Maquart et al., 1988). None of that converts into a per-day figure for a four-peptide blend.

That is why any KLOW dosage chart is an extrapolation across four literatures, not a measured result, and this page does not publish one. The one piece of arithmetic that is real is reconstitution: the millilitres of bacteriostatic water added to the vial set its strength in milligrams per millilitre. Our reconstitution calculator does that math and reports the result in units rather than mL. Any actual dose is a decision for a licensed clinician, not a number this page sets.

Research Timeline

What the studies measured, and when

Research timeline

What the studies measured, and when

The blend

KLOW is four peptides in one 80mg vial: BPC-157, TB-500, GHK-Cu and KPV. Each has its own published record.

BPC-157 and TB-500

Both are studied for soft-tissue repair endpoints, and the published record for each is dominated by animal models.

GHK-Cu

The strongest human evidence is topical, from 12-week trials measuring skin firmness and line depth (Pickart and Margolina, Int J Mol Sci 2018, PMID 29986520).

The combination

No published trial has measured these four together. Every figure available describes one component in isolation, so the blend itself is untested as a blend.

friday delivery as promised, timing was not a problem at all. sole note is they layered a little too much filler paper around things this time, more than strictly needed for what was inside, took two passes with the scissors before i could reach the vial tray underneath

Buying KLOW: FAQ

Where can I buy the KLOW peptide blend?

Peptara Labs sells KLOW online as a single 80mg vial holding BPC-157, TB-500, GHK-Cu and KPV, ordered from this page. It is sold as research-grade material for laboratory research use, so the batch certificate is the thing to compare between sources.

How much does KLOW cost?

One 80mg vial is $210 USD, which is $2.63 per mg across the four peptides. Signing up by email takes 15 percent off a first order, which brings a vial to $178. Buying more of the same compound lowers the per-vial price on that line, to 40 percent off at 10 vials, which is $126 each.

Does Peptara Labs ship KLOW to the US?

Yes. Orders to the United States, Canada, the United Kingdom and New Zealand ship tracked in 5 to 10 business days, guaranteed. Shipping is a flat $35, free over $250.

How do I verify the purity of KLOW before I buy?

Read certificate COA-2026-8537 for the released batch, lot KLW-260412-A: 98.60 percent purity by HPLC, identity by HPLC + LC-MS (per component), and 80.90 mg of net peptide in an 80mg vial, tested by Titreon Analytical. A blend certificate has to confirm identity for each of the four peptides, not once for the vial. Vials ship unlabeled, so your order number on WhatsApp is what ties your vial to its batch certificate.

What comes with a KLOW order?

One sealed 80mg vial of the lyophilized four-peptide blend and bacteriostatic water to reconstitute it, plus a printed reference guide to what published studies reported for each component. The batch certificate is published on the certificates page, because the vial itself ships unlabeled.

Is KLOW for human use?

No. KLOW is sold as research-grade material for laboratory research use only, not for human use. None of its four peptides is an approved medicine, and no published trial has studied the four together.

KLOW Combo FAQ

What is the KLOW Combo?

KLOW is four peptides in a single 80mg vial: BPC-157, TB-500, GHK-Cu and KPV. Each has a separate research area: BPC-157 for gut and tendon endpoints, TB-500 for systemic soft tissue, GHK-Cu for skin and collagen, KPV for anti-inflammatory signaling. The blend exists so one vial covers those four rather than four. No published trial has measured the combination itself.

Why use a blend instead of single peptides?

Convenience and coverage. Sourcing BPC-157, TB-500 and GHK-Cu separately means three vials and three reconstitutions. KLOW puts a fixed ratio of all of them, plus KPV, into one. For a single research target a solo vial is usually the cheaper route. What the blend does not do is inherit a trial: the combination has no published study of its own.

Is Peptara Labs a real company?

Yes. Peptara Labs is a registered business with responsive customer support via WhatsApp. Unlike anonymous Telegram sellers, we stand behind every order with our name, reputation, and ongoing support.

Are your peptides real?

Every KLOW Combo vial comes with a third-party Certificate of Analysis (COA) confirming purity. We source from verified manufacturers and can provide lab documentation upon request. If you want to see a COA before ordering, message us on WhatsApp and we'll send it over.

Will the peptides survive shipping and heat?

Yes. Peptides ship in their lyophilized (freeze-dried powder) form, which is stable at room temperature for weeks. Fast, tracked delivery keeps transit short. Once reconstituted with bacteriostatic water, store the vial in your refrigerator. Storage instructions are included with every order.

What does the research report for this blend?

For the blend as a blend, nothing: there is no published trial of these four peptides in combination. What exists is the record for each component separately, and for BPC-157 and TB-500 that record is dominated by animal models. Any timeline given for KLOW is extrapolation across four separate literatures, and this site does not publish one.

Should I still run BPC-157 or GHK-Cu separately?

The blend already contains both, so a separate BPC-157 or GHK-Cu vial alongside it duplicates two of the four components. Peptara Labs does not design combinations or adjust ratios for anyone.

What about side effects?

The components are generally reported as well tolerated, with mild injection-site irritation and temporary fatigue the most commonly reported effects. A copper allergy is a specific exclusion, because of the GHK-Cu component. None of the four has a large registered human safety trial, and the blend has none at all. Any dosing schedule is a decision for a licensed clinician.

How is the 80mg vial reconstituted?

Reconstitution is arithmetic: the milligrams in the vial divided by the millilitres of bacteriostatic water added to it. The reconstitution calculator on this site does that math and reports the result in units rather than mL. Storage instructions ship with every order. For anything medical, including how a compound is administered, speak with a licensed physician.

I can find cheaper peptides on Telegram.

You can. But you don't know what's in them, who made them, or how they were stored. Telegram sellers operate anonymously with no accountability. No COA. No real company behind them. No support if something goes wrong. Our price includes third-party testing, fast delivery, bacteriostatic water, COA access, and educational support. We don't just sell peptides. We make sure you get a verified, properly handled product you can trust.

How is KLOW different from a single GHK-Cu vial?

A GHK-Cu vial is one copper peptide, studied mainly for skin renewal and collagen (Pickart et al., 2018). KLOW keeps GHK-Cu but adds BPC-157, TB-500 and KPV, which shifts it from a skin-focused single peptide toward broad tissue, gut and skin coverage in one vial. If skin and collagen are the only goal, solo GHK-Cu is the more targeted option. Neither the blend nor the single has a trial of the four-peptide combination.

Is KLOW used for injury recovery?

Post-injury tissue repair is the studied research area for the components in KLOW: BPC-157 and TB-500 are both examined for soft-tissue and tendon endpoints, largely in animal models (Sikiric et al., 2020; Malinda et al., 1999), while GHK-Cu is studied for skin and wound repair (Pickart et al., 2018). The blend itself has no injury-recovery trial, so this describes what the component literatures report, not an outcome promise. Any protocol belongs with a licensed clinician.

Is my payment secure?

Yes. We accept Visa, Mastercard and Amex cards, bank transfer, and USDT, USDC or BTC crypto. All transactions are handled securely. For bank transfers, you'll receive confirmation once payment is verified. Your financial information is never stored. If you have concerns about a specific payment method, message us and we'll find an option that works for you.
