GLOW: 13 vendors compared
GLOW is a single vial holding GHK-Cu 50 mg + BPC-157 10 mg + TB-500 10 mg — 70 mg of peptide in all, at the ratio the vendors who itemise the vial print. 13 indexed vendors price it, from $1.21 to $2.93 per milligram of total peptide (median $1.46). At the median, 70 mg as a blend costs $102 against $145 for the same milligrams bought as separate vials — 29.5% less. No laboratory report indexed here assays GLOW as a blend with a purity figure per component, so the testing evidence on this page is each vendor's own certificates for GHK-Cu, BPC-157 and TB-500 — 28 checkable lots across 7 vendors.

|---|---|---|---|---|---|
| GHK-Cu | 50 mg | 71.4% | $0.600 | $30 | 40 / 42 |
| BPC-157 | 10 mg | 14.3% | $5.50 | $55 | 37 / 38 |

| Parts, bought separately | 70 mg | 100% | $2.07 | $145 | 101 / 105 |
| GLOW, as a blend | 70 mg | 100% | $1.46 | $102 | 0 |
The parts arrive as 3 vials rather than one, which is a real advantage — each can be dosed on its own and each can be assayed on its own. The blend arrives as one vial, which is cheaper to ship and, as the figures above show, not always cheaper to buy.

What a certificate can say about a blend
A laboratory testing a GLOW vial reports two different kinds of figure. It measures the content of each component— a Stealth Research Labs report on a CJC-1295 + Ipamorelin vial labelled 5 mg and 5 mg reads “5.33, 5.42 mg”, which is exactly the check a buyer wants. But it reports purity once, for the mixture as a whole: “overall purity 99.74%”. There is no per-component purity on the document.
So a blend report cannot be broken into one record per peptide without attaching to each part a purity figure the laboratory never measured. That is why 0 records on this index name GLOWitself, and why the testing column in the table above counts each vendor’s certificates for GHK-Cu, BPC-157 and TB-500 instead. A vendor that documents the parts properly is the closest thing to evidence about its blend that exists.
Vendors publishing a GLOW report are welcome to send it — we record blend reports as blend reports, with the content figures per component and the purity figure as the document states it, and never as 3 separate records.
Certificates for the parts
Questions this page answers
- What is in GLOW?
- GLOW is one vial holding GHK-Cu 50 mg + BPC-157 10 mg + TB-500 10 mg, 70 mg of peptide in total. Smaller vials of the same blend keep the ratio: a 35 mg vial is the same split halved. 3 compounds, each with its own research record and its own certificates on this index.
- Is GLOW cheaper than buying the peptides separately?
- At the market median, 70 mg of GLOW costs $102 as a blend and $145 bought as 3 separate vials at each compound's median price per mg. 0 of the 11 vendors that sell both the blend and all of its parts charge more for the blend than for the parts.
- Can a laboratory certificate prove what is in a GLOW vial?
- Only partly. A blend report measures how many milligrams of each component the vial holds, which is the useful part, but it reports purity once for the mixture as a whole. There is no per-component purity to publish, so a blend certificate cannot be split into one record per peptide without asserting a figure no laboratory measured. PepIndex records blend reports as blend reports and judges a vendor's blend on the certificates it holds for the component peptides.
