GLOW is a three-compound research peptide blend supplied in a single co-lyophilized vial: 10mg of BPC-157, 10mg of TB-500, and 50mg of GHK-Cu, for 70mg of total peptide content. Instead of sourcing, reconstituting, and verifying three separate compounds, laboratories studying multi-pathway peptide interactions work from one vial with one fixed composition. Heartland Bio Labs supplies GLOW for laboratory research use only, with independent analytical testing behind every product.
What is the GLOW peptide blend?
The name GLOW has become a shorthand across the research peptide market for a stack of three compounds: BPC-157, TB-500, and GHK-Cu. Different suppliers fill the vial differently, which is worth paying attention to, because "GLOW" describes a recipe, not a standard. The version matters. Heartland's GLOW is fixed at 10mg / 10mg / 50mg, stated on the label and on this page, so a research program always knows exactly what mass of each peptide is in the vial.
What is in the vial
- BPC-157 (10mg). A synthetic 15-amino acid pentadecapeptide derived from a gastric protein sequence, one of the most widely studied compounds in cytoprotection research. Full profile in our BPC-157 research overview.
- TB-500 (10mg). A synthetic fragment analogue of thymosin beta-4, the actin-binding peptide, studied for its role in cytoskeletal regulation. See the TB-500 research overview.
- GHK-Cu (50mg). The copper complex of the naturally occurring tripeptide glycyl-L-histidyl-L-lysine, a long-standing subject of research on copper-dependent cellular signaling. See the GHK-Cu research overview.
GLOW blend vs buying the three peptides separately
At current Heartland pricing, assembling the same masses from single vials costs more: BPC-157 10mg at $79, TB-500 10mg at $85, and GHK-Cu 50mg at $59 comes to $223 across three vials. The GLOW blend is $215 in one vial. The bigger difference for a laboratory is not the $8: it is one reconstitution instead of three, one fixed ratio instead of three hand-measured ones, and one certificate covering the finished blend. Programs that need to vary the ratio between compounds should buy the singles; programs studying the three together at a fixed ratio are what the blend exists for.
GLOW vs KLOW
KLOW is the same three compounds plus a fourth: 10mg of the tripeptide KPV, bringing the vial to 80mg. Research programs choose between them based on whether KPV's inflammation-signaling pathway belongs in the study design. The full breakdown is on the KLOW product page. If you are comparing the two, the practical summary: GLOW is the three-pathway blend at $215, KLOW is the four-pathway blend at $235.
How GLOW is verified
A blend is harder to verify than a single compound, and that is exactly why verification matters more here. A single purity number on a three-peptide vial tells you very little; meaningful analysis has to identify and quantify each component. Heartland's products are tested by an independent analytical laboratory using HPLC for purity and mass spectrometry for identity, and published certificates are available in our COA portal. If you are evaluating any supplier's GLOW blend, ours included, our guide on how to vet a research peptide supplier gives you the checklist: demand component-level data, not a single headline number.
Pricing and availability
GLOW ships as the 70mg triple blend (10mg BPC-157 / 10mg TB-500 / 50mg GHK-Cu) at $215, in stock with same-day dispatch from the Tulsa, Oklahoma area for orders placed before 2:00 PM Central. A smaller 60mg configuration appears on the strength selector with a notify option when it is not in stock. Institutional volume runs through our wholesale program.
Storage and handling
Lyophilized, the blend is stable kept sealed, cool, dry, and away from light, with refrigeration recommended for longer storage. Reconstitute with bacteriostatic water; because three peptides share the vial, gentle swirling rather than agitation matters more than with a single compound. Refrigerate after reconstitution and use within the window your research protocol defines.
Where to buy the GLOW peptide blend
Most results for GLOW are clinics selling treatment programs, not suppliers selling verified research material. If you are buying the blend itself, the questions that separate suppliers are the ones above: does the vendor state the exact composition by mass, does independent testing back it, and can you read the certificate before paying. Heartland publishes all three answers. Compare us on documentation against anyone.
Reconstitution math
Work out concentration (mg/mL), amount per volume and molarity for any vial size with the BPC-157 reconstitution calculator, TB-500 reconstitution calculator, GHK-Cu reconstitution calculator, general peptide calculator. For the bench procedure see how to reconstitute peptides.
Research use only
GLOW from Heartland Bio Labs is sold strictly for laboratory research and identification purposes. It is not a drug, it has not been evaluated by the FDA, and it is not for human or veterinary use of any kind. By purchasing, you affirm that you are qualified to handle research compounds and agree to our research use policy.
