What is KLOW blend?
Plain language first. The technical label stays, but it never stands alone.Overview
It is an all-in-one recovery-and-skin stack in a single shot.
KLOW is the GLOW blend (GHK-Cu, BPC-157, TB-500) with KPV added for extra anti-inflammatory effect.
What it's used for
The GLOW mix plus an anti-inflammatory peptide, a common all-in-one recovery-and-skin stack.
How does KLOW blend work?
What it does in the body, and where.KLOW is the GLOW blend with KPV added, making four peptides in one injection.
- 01The GLOW components handle skin and tissue repairGHK-Cu for collagen, BPC-157 and TB-500 for tissue.
- 02KPV adds an anti-inflammatory actionInterrupting inflammatory signalling from inside the cell.
- 03Four unstudied compounds in one vialEach has thin human evidence individually. Combined, there is none at all, and no way to tell which component is responsible if something helps or goes wrong.
Where this compound is thought to act.
What else is it used for?
Each use below carries its own evidence level. Approved means regulators have cleared it for that purpose. Investigational means it is in trials. Early research means it is being studied and is not established.

- Healing tendons, muscle, and gutEarly research
- Calming inflammation, which is what the fourth peptide adds over the GLOW blendEarly research

No published study has established how long to take this or whether a break is needed. Schedules quoted online come from vendors and forums, and different sources disagree.

How do I dose and price it?
Enter your vial and your dose. Pick a mix. We show the draw and the cost.The vial holds a fixed amount of drug. Adding more water does not make more drug, it just spreads it thinner, so you draw a bigger number on the syringe for the same dose.
KLOW is GLOW with 10 mg of KPV added. The 80 mg vial is the common size.

How do you store it?
Before mixing, and after.Dry powder in the freezer or fridge. Once mixed, fridge, and use within about a month.
Unmixed lyophilized KLOW blend keeps for a long time cold. Once you add water the clock starts: most reconstituted vials hold up for roughly 28 to 30 days at fridge temperature. Keep it out of light, and do not freeze it after mixing.
What are the side effects and cautions?
Known cautions and warnings for this compound.Who should avoid it
- A known copper allergy or metal sensitivity, so patch test first
- Broken or actively irritated skin
- Layering with strong acids or retinoids on the same area
- Active cancer, as a precaution given that it promotes new blood-vessel growth
- Pregnancy
- Banned in drug-tested sport
- Active cancer, as a precaution given the tissue-growth mechanism
- No controlled human trials exist, so no contraindications are established
Stop and get help
- A spreading rash or significant swelling where applied
- Signs of an allergic reaction
- New lumps or masses
- Anything unusual, given the absence of human data
Common effects
- Mild, temporary skin irritation, redness, or itching
- Among the least irritating copper compounds in comparison studies
- The good safety record applies to topical use. Injectable and oral forms lack this database
- Generally well tolerated in the limited data that exists
- Injection-site reactions
- Almost all evidence is from animals, so the human profile is not established
- Head rush or lightheadedness shortly after injecting
- Tiredness
- Unknown in humans. Anti-inflammatory effects have only been shown in cells and animals
- This is a four-peptide blend, so the cautions of every component apply at once, and a reaction is harder to trace to one ingredient.

What has happened recently
We have not yet written a full regulatory note for this compound. The status above is current as of the date shown.
Banned in drug-tested sport. Most research peptides are prohibited under WADA's S0 category, which covers any substance with no approval from any regulatory authority for human use. That means a compound can be banned without ever being named on the prohibited list. Check with your own anti-doping authority rather than assuming absence from the list means permitted.

- FDA, bulk drug substances for compounding that may present significant safety risks(2026)BPC-157 was placed in 503A category 2 on 29 September 2023, citing possible immunogenicity for certain routes and complexities with peptide-related impurities and API characterization. As of the 22 April 2026 version of this page, the substance sits in the second table, headed bulk drug substances nominated but withdrawn, rather than in the live category 2 list. The nomination was withdrawn, which is not the same as being approved or cleared: FDA still publishes the safety language above, and no longer has a nomination in front of it to evaluate.

None of those is the use this blend is sold for.
