What it is
Glow adds GHK-Cu to the BPC-157 and TB-500 pair. GHK-Cu is best known for collagen and skin research, so the blend is marketed toward skin and tissue repair. Expect a blue tint from the copper complex.
Components
- BPC-157: Gastric-protein fragment studied for tendon, gut and soft-tissue healing in animals. 503A compounding under interim HHS policy
- TB-500: Synthetic version of the actin-binding region of thymosin beta-4. 503A compounding under interim HHS policy
- GHK-Cu: Copper-binding tripeptide from human plasma, widely used in skincare. Research use only
What the research shows
Each component has its own body of mostly preclinical research, summarized on its brief. No published controlled studies have tested these combinations as blends, so any benefit of combining them is theoretical.
Reconstitution math
Blend labels usually state the total mg in the vial. When you use the calculator, the result refers to the total blend; multiply by each component's share of the total to get its amount. Check the label or certificate of analysis for the ratio.
Storage and handling
Lyophilized (freeze-dried) powder is most stable sealed, dry and protected from light. Laboratory practice is to keep unopened vials frozen at about -20 °C for long-term storage, or refrigerated at 2 to 8 °C for shorter periods. After reconstitution, keep the solution refrigerated at 2 to 8 °C, avoid repeated freeze-thaw cycles and use aseptic technique for every draw. Formal stability data in solution has not been published for most research peptides, so follow the supplier's label and certificate of analysis.
