What GLOW is
GLOW is a marketing name, not a defined product. It refers to a single vial containing three peptides: GHK-Cu, BPC-157, and TB-500. It is sold mainly for skin, recovery, and "glow-up" goals.
There is no standard formula. One seller's GLOW may be 70 mg total with most of it GHK-Cu, while another's is 42 mg with a different split. Unless the label lists each component's amount, you cannot know what you're working with.
Regulatory status in 2026
A blend cannot be more legal than its least legal ingredient. None of the three components is an approved drug, none is on the compounding list, and a pre-mixed vial of them has never been evaluated by FDA in any form.
All three components are removed from FDA's Category 2 list. This does not make any of them legal to compound.
FDA's advisory committee narrowly recommends adding BPC-157 and TB-500 to the compounding list. GHK-Cu was not on that docket.
No component is on the compounding list. BPC-157 (WADA S0) and TB-500 (WADA S2) are banned in sport at all times.

Claims vs. what the research shows
Each ingredient has its own evidence base, covered on its own page. The blend itself has none.
The three work together better than alone.
No study has tested this combination in people or animals. "Synergy" claims are marketing.
Insufficient dataImproves skin quality.
Small topical studies support GHK-Cu on skin. No evidence for injected GHK-Cu or for the blend.
Insufficient dataSpeeds injury recovery.
Based on animal studies of BPC-157 and thymosin beta-4 separately.
Animal or limited evidenceStorage and stability
Peptides break down with heat, light, moisture, and repeated freezing and thawing. Degraded product is one common reason two vials of the "same" peptide behave differently. These are general peptide handling practices. Your supplier's certificate of analysis or label takes priority. A blend can only be as stable as its least stable ingredient, and no stability data exists for these combinations.
Sealed powder (lyophilized)
- Refrigerate at 36 to 46°F (2 to 8°C) for routine storage.
- Freezer is generally used for long-term storage.
- Keep in its original sealed vial, away from light.
- Let a cold vial reach room temperature before opening to limit condensation.
After reconstitution
- Keep refrigerated. Do not freeze.
- Protect from light. Clear glass lets it through.
- Opened multi-dose bacteriostatic water is typically discarded 28 days after first puncture.
- Log the mix date so you know the vial's age at a glance.
Light exposure is easy to overlook in a fridge door that opens dozens of times a day. VIALTIGHT is building stackable cases that block light from every side. See vialtight.com for updates.
Blend math
With a blend, each ingredient has its own concentration. Enter the amount of each from your vial's label and the water you added. On a U-100 syringe, each unit is 0.01 mL. The defaults are a common seller's formula, not a standard.
This shows concentration only. It is not a dosing recommendation. If your label lists only a total amount, you can't calculate this, which is itself a red flag.
Safety flags
Product quality is unverified. Gray-market vials have been found underdosed, mislabeled, or contaminated. A certificate of analysis from the seller is not the same as independent testing.
You can't verify each ingredient. Many certificates of analysis for blends only report total purity. Ask for amounts of each component.
Unknown interactions. No one has studied what these three do together in the body.
Tested athletes. Contains BPC-157 (WADA S0) and TB-500 (WADA S2), both banned at all times.
FAQ
What's the difference between GLOW and KLOW?
KLOW is GLOW plus a fourth peptide, KPV. Exact amounts of each vary by seller.
Is GLOW a brand?
No. It is a nickname used by many sellers for a similar mix. Two GLOW vials from different sellers may not match.
Does VialTracker tell me what to take?
No. VialTracker organizes the information you enter and runs the math. It does not recommend doses, products, or protocols.
