GLOW blend: dosing evidence and reconstitution math
For a blend, every component is diluted together: divide each component's labeled amount by the diluent volume to get that component's concentration.
Is there an established dose?
No FDA label or published human trial defines a dose of GLOW blend, so we do not publish one. Online "protocols" for it are not evidence.

How blend concentration works
A blend vial lists an amount for each component. After adding diluent, each component's concentration is its own amount divided by the diluent volume: a component listed at 10 mg in 2 mL is 5 mg/mL, and every draw contains all components in the labeled ratio. You cannot change one component's amount without changing the others.
Use the peptide calculator once per component.
The components and their evidence
- GHK-Cu: not approved (research only). PubMed indexes 83 records and ClinicalTrials.gov lists 3 registered studies under its name. GHK-Cu is the copper complex of the tripeptide glycyl-histidyl-lysine, found in human plasma and widely used in topical cosmetics.
- BPC-157: not approved (research only). PubMed indexes 222 records and ClinicalTrials.gov lists 4 registered studies under its name. BPC-157 is a 15-amino-acid synthetic peptide derived from a protein in gastric juice, studied mostly in animal models of tissue injury; it is not an FDA-approved drug.
- TB-500: not approved (research only). PubMed indexes 602 records and ClinicalTrials.gov lists 18 registered studies under its name. TB-500 is a synthetic peptide based on the active region of thymosin beta-4, studied in animal injury models; it is on WADA's prohibited list.
No study we found tested these 3 components together as a single product, so any claim about the blend's combined effect is extrapolated from separate research on each one.

Where research vials are listed
38 suppliers in our directory list GLOW blend (A–Z): Amino Amigos, Ascension Peptides, Atomik Labz, BioGenix Peptides, BioLongevity Labs, Bulk Peptide Supply, Core Peptides, Costides, and 30 more. A listing is not a quality endorsement; ask for a lot-specific certificate of analysis.
Storage & handling
Follow the storage statement on the product sheet or certificate of analysis. Lyophilized (freeze-dried) peptides are generally kept cold, dry and away from light; once reconstituted, stability is shorter and depends on the compound and diluent. Bacteriostatic water contains 0.9% benzyl alcohol as a preservative; sterile water does not.
