GLOW + KPV. Anti-inflammatory boost.
KLOW extends the GLOW formula with KPV*, a tripeptide fragment of α-melanocyte-stimulating hormone (α-MSH). Preclinical research has explored KPV for anti-inflammatory activity, particularly in the context of intestinal and dermal inflammation.
The stack addresses recovery loads that are inflammatory as well as structural — systemic inflammation after training, chronic dermal irritation, or gut-adjacent repair. Stacking KPV with BPC-157, TB-500, and GHK-Cu creates a 4-peptide protocol* in a single reconstitution.
At 80 mg total peptide* per vial, KLOW is the highest-strength formulation in the skin + healing category.
Every lot is independently tested before it ships. The document shown is an example of the format. The COA for your exact lot comes by email.

KLOW is GLOW plus a fourth peptide, KPV. GLOW is a 70mg blend of BPC-157, TB-500 and GHK-Cu; KLOW is an 80mg blend that adds KPV.
Read the guide: KLOW vs GLOW →KPV is a tripeptide made of lysine, proline and valine. It is a short fragment of the hormone α-MSH. It is the "K" in KLOW.
Read the guide: KLOW vs GLOW →A lyophilized (freeze-dried) powder in a sealed vial labelled with its lot code and expiration date. Freeze-drying removes the water, which keeps the peptide stable in storage.
Read the guide: What does lyophilized mean? →Keep sealed vials refrigerated at 2–8°C and away from light. Let a cold vial reach room temperature before opening it, so moisture does not condense on the powder.
Read the guide: How to store research peptides →Each batch is tested by an independent third-party lab. The COA for your lot is available by email on request: send the lot code printed on your vial to contact@vitalitipeptide.com.
Read the guide: How to read a peptide COA →It ships from within Canada. Orders placed before 2pm EST on a weekday ship the same business day; most addresses receive them next day or in 1–2 business days, and northern or remote postal codes usually take 4–5 business days. Shipping is a $15 flat rate, free over $300; subscriptions ship for $7.50, free over $150.
Read the guide: Peptide shipping in Canada →No. It is sold for laboratory research use only. It has not been evaluated or approved by Health Canada and is not for human consumption.
“Higher concentration than GLOW, packaging was the same standard. KPV inclusion is the differentiator — vitalitiRX is one of the few Canadian sources that publishes COA data on multi-peptide blends including KPV.”
“Ordered after running GLOW for two cycles. Stepped up to KLOW for a stronger formula. Same vial quality, same lot-traceability process, same documentation.”
“The 80mg size means fewer reconstitutions across a longer research window. Packaging was solid. Wish the product page detailed the KPV component a bit more — had to dig through the FAQ to find the source publication.”
