In this KLOW 80mg peptide blend guide, we cover what is in the blend, how it is studied, and how to verify and handle it properly.
KLOW 80mg is a four-compound research blend that combines GHK-Cu, BPC-157, TB-500, and KPV in a single lyophilized vial. It is studied as a KLOW 80mg peptide blend for multi-pathway research — bringing tissue-repair, angiogenic, and anti-inflammatory peptides together at fixed ratios so a research model can be exposed to all four compounds at once, without reconstituting four separate vials. This guide covers exactly what is in KLOW, how each compound is studied, how the blend is reconstituted, expected vial longevity, and the quality standards that matter. KLOW is supplied strictly for laboratory research use. View the KLOW peptide 80mg blend (lot COA included).
What Is KLOW 80mg?
KLOW 80mg is a pre-formulated peptide blend containing 80mg of total net peptide content across four compounds. The “80” in the name refers to the combined milligram weight of all four peptides in the vial. KLOW is one of two flagship CoreVionRX research blends — the four-compound KLOW and the three-compound GLOW. Where a single peptide targets one pathway, the KLOW blend is built for researchers studying overlapping repair and inflammatory pathways at the same time. If you have searched “what is KLOW 80” or “klow 80mg what is it,” the short answer is: a fixed-ratio four-peptide research blend totaling 80mg.
KLOW 80mg Composition and Ingredients
The KLOW peptide blend composition is built around a high-mass copper peptide base with three supporting compounds. The full KLOW peptide blend ingredients are:
| Compound | Amount | Primary Research Role |
|---|---|---|
| GHK-Cu | 50mg | Copper-binding tripeptide — collagen synthesis, gene-expression regulation |
| BPC-157 | 10mg | Body Protection Compound — angiogenesis, wound-healing models |
| TB-500 | 10mg | Thymosin Beta-4 fragment — cell migration, actin regulation |
| KPV | 10mg | Alpha-MSH fragment — anti-inflammatory (NF-κB pathway) |
| Total net peptide | 80mg | |
Each of the four components carries a lot-specific Certificate of Analysis confirming identity and purity, not just total mass.
The Four Compounds and Their Research Mechanisms
GHK-Cu (50mg) — The Foundation of the Blend
GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper) is the largest component by mass and the backbone of KLOW. It is a naturally occurring copper-binding tripeptide found in human plasma, and research has examined its role in collagen synthesis, fibroblast activity, and the regulation of matrix metalloproteinases. Notably, gene-expression studies have associated GHK-Cu with the modulation of thousands of genes tied to tissue remodeling and the inflammatory response, which is why it is studied as a foundational “signal” peptide in repair models.
BPC-157 (10mg)
BPC-157 is a 15-amino-acid partial sequence derived from a protein found in gastric juice. It is one of the most extensively studied compounds in angiogenesis and wound-healing research, with models focusing on tendon-to-bone healing, new blood-vessel formation, and gastrointestinal tissue repair. Its stability and consistent angiogenic signal make it a common pairing with TB-500, as in the two-compound BPC-157 + TB-500 Wolverine stack.
TB-500 (10mg)
TB-500 is the biologically active fragment of thymosin beta-4 (amino acids 17–23). Research focuses on its role in actin regulation, cell migration, and the promotion of new blood-vessel formation. It is frequently studied alongside BPC-157 because the two act through complementary tissue-repair pathways rather than the same one.
KPV (10mg)
KPV (Lys-Pro-Val) is a tripeptide fragment from the C-terminal region of alpha-MSH (alpha-melanocyte-stimulating hormone). It is studied for anti-inflammatory activity, particularly through modulation of the NF-κB signaling pathway. KPV is the component that distinguishes KLOW from the three-compound GLOW blend, adding an explicit anti-inflammatory dimension to the formula.
Why KLOW Is Studied as a Multi-Pathway Blend
The logic behind KLOW is overlap. GHK-Cu drives remodeling and gene-expression signaling; the BPC-157 and TB-500 pairing covers angiogenesis and cell migration; KPV adds anti-inflammatory modulation. Studying these as a fixed-ratio blend lets a research model engage tissue-repair and inflammatory pathways simultaneously, while controlling for relative dosing across the four peptides. It also removes a major source of variability — reconstituting, measuring, and handling four separate compounds — which is why fixed-ratio blends are popular for multi-pathway research.
For a deeper understanding of how peptide blends are formulated, see the PubMed research on peptide combination studies.
KLOW vs GLOW: What Is the Difference?
GLOW is a 70mg three-component blend (GHK-Cu + BPC-157 + TB-500). KLOW is the 80mg four-component blend that adds KPV. In practice: GLOW is the tissue-repair and angiogenesis blend; KLOW is GLOW plus a dedicated anti-inflammatory peptide. Researchers comparing single-pathway versus multi-pathway approaches frequently run both side by side.
How to Reconstitute KLOW 80mg
KLOW reconstitution follows the same principles as any lyophilized peptide: bacteriostatic water is added slowly down the side of the vial, never injected directly onto the powder, and the vial is swirled rather than shaken until fully dissolved. Because KLOW contains four peptides at 80mg total, the reconstitution volume you choose determines the concentration of every component proportionally. A common approach is to reconstitute with a volume that produces convenient working concentrations for the research model. For full step-by-step technique, see our complete reconstitution guide, and use the KLOW preparation calculator to convert any reconstitution volume into exact per-unit concentrations.
How Much Bacteriostatic Water for 80mg KLOW?
There is no single required volume. The amount of bacteriostatic water you add only sets the concentration. Most researchers choose between 2 and 5 mL, depending on vial size and how finely they want to measure. Here is what each volume works out to:
| Bacteriostatic water added | Total blend | GHK-Cu | BPC-157 / TB-500 / KPV (each) |
|---|---|---|---|
| 2 mL | 40 mg/mL | 25 mg/mL | 5 mg/mL |
| 3 mL | 26.7 mg/mL | 16.7 mg/mL | 3.3 mg/mL |
| 4 mL | 20 mg/mL | 12.5 mg/mL | 2.5 mg/mL |
| 5 mL | 16 mg/mL | 10 mg/mL | 2 mg/mL |
The math is the same for any volume: divide each compound’s mass (50mg GHK-Cu, 10mg each of BPC-157, TB-500 and KPV) by the millilitres added. Larger volumes give lower concentrations, which makes small amounts easier to measure accurately. Once reconstituted, keep the vial refrigerated (2-8°C). See the peptide storage guide for how long solutions stay stable.
KLOW Research Protocols and Working Concentrations
Because KLOW is a fixed-ratio blend, research protocols are typically expressed as a total blend amount per use in the model, which then breaks down proportionally across the four compounds (GHK-Cu making up roughly 62.5% of any given amount, with BPC-157, TB-500, and KPV each contributing 12.5%). When designing a KLOW 80mg protocol, researchers calculate the working concentration from their chosen reconstitution volume and then determine per-use volumes from there. The KLOW preparation calculator handles this conversion so the four-peptide ratio stays consistent across the study.
How Long Does an 80mg KLOW Vial Last?
Vial longevity is simple arithmetic: total milligrams divided by the per-use amount used in the research model equals the number of uses. An 80mg vial used at, for example, 2mg of total blend per use would yield roughly 40 uses; at 4mg per use, roughly 20. The exact figure depends entirely on the protocol design. Once reconstituted, the blend should be refrigerated and used within the stability window appropriate for the compounds; lyophilized (unreconstituted) KLOW stored frozen has a substantially longer shelf life.
KLOW Storage, Shelf Life and Color
KLOW needs refrigeration once it is dissolved. Keep the sealed powder frozen at -20°C, away from light and moisture, and keep the dissolved blend refrigerated at 2–8°C. These are the storage conditions listed on the KLOW 80mg product page.
| State | Temperature | What to expect |
|---|---|---|
| Sealed powder, long term | -20°C (freezer), dark and dry | Lyophilized peptides stored this way generally stay stable for months, often longer |
| Sealed powder, short periods | Room temperature | Tolerated for days up to a few weeks, which is why it ships without ice |
| Dissolved blend | 2–8°C (refrigerator) | No stability data is published for the KLOW mix in solution; prepare only what the lab work needs and date the vial |
What color is KLOW? Blue, both as a powder and once dissolved. GHK-Cu makes up 50 of the 80mg, and its copper gives the blend its blue color, so a blue vial is normal. A clear blue solution is expected; cloudiness or visible particles mean the vial should be set aside and checked against the lot COA.
The peptide storage guide explains why heat, light and repeated warming matter.
Quality Standards: COA and Purity
A four-peptide blend raises the bar for verification. The Certificate of Analysis should confirm the identity and purity of each individual component — not simply the combined mass. CoreVionRX supplies KLOW with a lot-specific COA including HPLC purity (≥99%) and mass-spectrometry identity confirmation for each of the four peptides. For researchers, this is the difference between knowing you have 80mg of “something” and knowing you have a verified 50/10/10/10 split of the correct compounds.

Frequently Asked Questions
What is KLOW 80mg?
KLOW 80mg is a four-compound research blend containing GHK-Cu (50mg), BPC-157 (10mg), TB-500 (10mg), and KPV (10mg) — 80mg of total net peptide in one lyophilized vial, studied for multi-pathway tissue-repair and anti-inflammatory research.
What is in the KLOW peptide blend?
The KLOW blend composition is GHK-Cu 50mg, BPC-157 10mg, TB-500 10mg, and KPV 10mg. GHK-Cu makes up the majority of the mass, with the three supporting peptides each at 10mg.
How do you reconstitute KLOW 80mg?
Add bacteriostatic water slowly down the side of the vial and swirl gently until dissolved. The reconstitution volume sets the concentration of all four peptides proportionally. The KLOW preparation calculator converts your chosen volume into exact per-unit concentrations.
How much bacteriostatic water do you add to 80mg KLOW?
Most researchers add between 2 and 5 mL. 2 mL gives 40 mg/mL of total blend, 4 mL gives 20 mg/mL and 5 mL gives 16 mg/mL. The volume only changes the concentration, not the amount of peptide in the vial.
How long does an 80mg KLOW vial last?
Divide 80mg by the per-use amount in your research model. At 2mg per use, an 80mg vial yields about 40 uses; at 4mg per use, about 20. The exact number depends on protocol design.
What is the difference between KLOW and GLOW?
KLOW is the 80mg four-compound blend (GHK-Cu + BPC-157 + TB-500 + KPV). GLOW is the 70mg three-compound blend (GHK-Cu + BPC-157 + TB-500). KLOW adds KPV for anti-inflammatory research.
Does KLOW need to be refrigerated?
Yes, once it is dissolved: keep the solution at 2–8°C. The sealed powder belongs in the freezer at -20°C, away from light and moisture, and tolerates room temperature only for short periods, such as shipping.
How long does KLOW last in the fridge?
No stability study has been published for the four-peptide KLOW mix in solution, and CoreVionRX does not state a fixed refrigerated window. Dissolved peptides are far less stable than the dry powder, so prepare only what the lab work needs, keep it at 2–8°C and write the preparation date on the vial.
What is the shelf life of KLOW?
Sealed, lyophilized KLOW stored frozen at -20°C, away from light and moisture, generally stays stable for months and often longer. At room temperature the sealed powder tolerates days up to a few weeks. Once dissolved, it is far less stable.
What color is KLOW peptide?
KLOW is blue, both as a powder and once dissolved. The color comes from the copper in GHK-Cu, which makes up 50 of the 80mg, so a blue vial is normal.
How much GHK-Cu and KPV is in KLOW?
Each KLOW 80mg vial holds 50mg of GHK-Cu (62.5% of the blend) and 10mg of KPV (12.5%), plus 10mg each of BPC-157 and TB-500.
Does KLOW come with a COA?
Yes. CoreVionRX supplies KLOW with a lot-specific Certificate of Analysis showing HPLC purity and mass-spectrometry identity, so the lot number on the vial can be matched to the test data.
