If you want to buy GLOW peptide, the 70mg GHK-Cu + BPC-157 + TB-500 blend, Ascension Peptides is the cheapest at 70mg — $55.00 a vial (50% off sitewide through our link). Vendors also list it as GLOW 70, the glow stack or glow blend peptide; every name means the same vial of 50mg GHK-Cu, 10mg BPC-157 and 10mg TB-500.
Research-context information only. GLOW contains GHK-Cu, BPC-157, and TB-500 — research peptides not approved by the FDA. BPC-157 and TB-500 are on the FDA 503A bulks Category 2 list (2023). Protocols, doses, and reactions reported below come from published research and self-reported community sources. This article reports what has been documented, not what should be done. Consult a licensed physician for personal medical decisions.
The buying problem is per-component COA verification: vendors must independently test GHK-Cu (with copper bound), BPC-157, and TB-500. Vendors that publish only "blend purity" without per-component certificates cannot confirm the labeled ratios.
This guide covers today's 70mg prices, true price per mg, blend COA verification, and red flags. For dosing context, see the GLOW dosing guide; the ranked list is on Best GLOW Peptide Vendors.
GLOW 70 Prices Today: What a 70mg Vial Costs
GLOW ships as a single lyophilized 70mg vial. Most vendors use the standard ratio (50mg GHK-Cu + 10mg BPC-157 + 10mg TB-500). Three factors drive price: total mg in the vial, vendor markup, and per-component testing investment.
Nura Peptide $63.00 · EZ Peptides $79.20 · Ion Peptide $67.15 · Mile High Compounds $98.99
Prices are single vials through our links, with each vendor's standing code or link discount applied.
Price per mg is the vial price divided by 70. The 70 is the whole vial, not one component, so a $90 vial works out to about $1.29/mg. Total-mg pricing also hides per-component economics: GHK-Cu is cheap to make and fills 50 of the 70mg, while BPC-157 and TB-500 are the costlier, smaller parts. The blend wins on cost per mg mainly because it is GHK-Cu-dominant.

A cycle's cost is the vial count times one vial's price: the lowest 70mg vial today is $55.00 at Ascension Peptides. That is price arithmetic on community-reported amounts, not dosing guidance; the GLOW cost calculator runs it for every vendor.
How to Verify a GHK-Cu + BPC-157 + TB-500 Blend COA
A 3-peptide blend COA requires three separate test reports. Counterfeit patterns documented in community discussions: vendors substitute a TB-4 fragment for full TB-500 (saves ~$5/mg synthesis cost), or skip GHK-Cu copper-binding verification (selling free GHK without copper is much cheaper but biologically distinct).
What a GLOW COA Should Include
Identity Confirmation — All Three Peptides
Mass spec confirming GHK-Cu (~403 Da, peptide + copper)
Mass spec confirming BPC-157 at 1,419.5 Da
Mass spec confirming TB-500 (Tβ4) at 4,963 Da
Purity Testing — All Three Peptides
HPLC purity at 98%+ for each peptide individually
Three HPLC chromatograms, each showing a single dominant peak
Copper-Binding Verification (specific to GHK-Cu)
Atomic absorption or ICP-MS confirming copper presence
Free GHK (without Cu) reportedly has different bioactivity and costs less to make
Contamination Testing
Endotoxin levels
Residual solvent analysis
Heavy metals screening (with Cu separately quantified)
How to Verify a Blend COA Is Legitimate
Three separate test reports (not a single "blend COA")
All three components reconstituted with bacteriostatic water and refrigerated are commonly cited by community sources as stable for roughly 28 days. With sterile water (no preservative), the window collapses to ~24 hours.

Borderline
Community sources note that at commonly reported daily amounts, a 70mg vial slightly exceeds the 28-day stability window. Community sources describe staged reconstitution, mixing half the vial first and the second half once the first is finished.
Community-Reported Vial Sizing
Tolerance testing:
70mg is the smallest commonly-stocked size — no smaller "tolerance vial" exists for GLOW
Some users buy a small BPC-157 + TB-500 blend separately first to assess tolerance before committing to GLOW
Commonly reported pattern:
70mg GLOW vial with staged reconstitution
1-2 vials per month at heavy use; 1 vial per 2 months at lighter use
Extended cycles (12+ weeks):
Multi-vial packs (where offered) lower the price per mg; the live comparison shows current pack prices

KLOW adds KPV (10mg) for additional anti-inflammatory mechanism, often at very similar pricing. Vendors and community sources describe GLOW as the more skin-focused option and KLOW as the broader recovery option. See the KLOW blend buying guide for that comparison.

Is GLOW peptide the same as a glow stack or Glow blend?
Yes. GLOW peptide, the glow stack, Glow blend, glow blend peptide and GLOW 70 are vendor and community names for the same product: one vial holding GHK-Cu, BPC-157 and TB-500 together. The names vary by vendor; the contents are what matter, so the label and COA should list all three peptides with their individual amounts.
What does GLOW 70 mean?
The 70 is the total peptide content of the vial in milligrams: 50mg GHK-Cu + 10mg BPC-157 + 10mg TB-500 = 70mg. GLOW 70 and GLOW 70mg describe the standard vial. Price per mg for this blend is the vial price divided by 70.
What is in GLOW peptide?
The standard GLOW ratio is 50mg GHK-Cu (the copper-bound tripeptide), 10mg BPC-157 and 10mg TB-500 in a single lyophilized vial, which is why it is also listed as a GHK-Cu + BPC-157 + TB-500 blend. Some boutique vendors sell other ratios, so the per-component amounts on the COA are the thing to check.
Is GLOW peptide legal to buy?
All three components (GHK-Cu, BPC-157, TB-500) are sold as research chemicals labeled 'not for human consumption.' Per FDA's published 503A bulks list, BPC-157 and TB-500 are in Category 2. GHK-Cu is permitted in cosmetic topical products but the injectable form is research-grade only. Sellers label these products not for human consumption and sell them as research chemicals; the legal status of purchase and possession varies by jurisdiction and is not addressed here.
How much does GLOW peptide cost?
In our October 20, 2026 price check, list prices for a single 70mg GLOW vial ran from $79 to $110 across the five recommended vendors we track, or $1.13 to $1.57 per mg before discount codes. Codes and link discounts bring the paid price lower; the comparison on this page shows today's figures.
Is GLOW cheaper than buying GHK-Cu, BPC-157, and TB-500 separately?
At the vendors we track, yes. In our October 20, 2026 price check, a 50mg GHK-Cu vial plus 10mg BPC-157 and 10mg TB-500 vials listed at $122 to $127 combined at vendors selling all three, against $85 to $88 for the same vendors' 70mg GLOW vial, about 30% less.
What purity should I look for in GLOW peptide?
Per-component HPLC at 98%+ purity for all three peptides individually. Mass spec must confirm GHK-Cu (340 Da peptide + Cu = 403 Da total), BPC-157 (1,419.5 Da), and TB-500 (4,963 Da). A single combined COA is insufficient.
Can I buy GLOW peptide from a compounding pharmacy?
No. Per FDA's published 503A bulks list, BPC-157 and TB-500 are in Category 2. GLOW is only available through research peptide vendors.
