GLOW 70 mg Blend

Healing & recovery Research compound (not approved for human use)

Tissue-repair and skin-support blend (three peptides) · also known as GLOW peptide blend, GHK-Cu + BPC-157 + TB-500

For reference only — not medical advice. Figures are commonly reported values compiled from published sources and may be wrong or out of date. Many compounds listed are not approved for human use. Talk to a licensed clinician before using any compound.

This 70 mg vial is mostly GHK-Cu (50 mg) with 10 mg each of BPC-157 and TB-500, so it leans toward collagen and skin remodeling research while keeping the recovery pairing. The reported schedule is a single fixed amount for four weeks.

Commonly reported dosing (70 mg vial)

Reconstituted with 3 mL → 23.333 mg/mL.

Commonly reported reconstitution steps

Vials are usually brought to room temperature (about 15-20 minutes) first.
3 mL of bacteriostatic water is added slowly down the inside wall of the 70 mg vial.
The vial is swirled gently until clear, not shaken.
This gives 23.33 mg/mL. Mixed vials are typically labeled with the date and refrigerated.

Storage

Before mixing: Sealed vials are commonly stored refrigerated (2-8 °C) and protected from light, or frozen for long-term storage.

After mixing: Reconstituted solution is commonly kept refrigerated (2-8 °C), protected from light, and not frozen.

Commonly used within 28 days of mixing.

How it works

GHK-Cu is a copper-binding tripeptide associated with gene-expression changes tied to collagen synthesis and tissue remodeling. BPC-157 is linked to angiogenesis and growth-factor signaling, and TB-500 (a thymosin beta-4 fragment) to actin regulation and cell migration.

Researched for

Studied in wound-healing and tissue-remodeling research for each component.
Investigated in animal models of tendon, muscle and gut repair (BPC-157, TB-500).
Skin and collagen studies for GHK-Cu, mostly topical or in vitro.

Notes

The three-peptide mixture has no published human trials; evidence is per component and mostly preclinical.
Because it is a blend, the per-dose amount covers all three peptides in a 5:1:1 mass ratio.
Copper peptides can cause local irritation in some reports.
Reconstituted solution is commonly refrigerated.

GHK-Cu

Copper-binding tripeptide

GHK-Cu is a naturally occurring copper-binding tripeptide studied for skin, hair, and tissue-remodeling applications.

50 mg vial · Once daily, 5 days per week, subcutaneous (topical formulations are also used)

BPC-157

Synthetic pentadecapeptide

BPC-157 is a synthetic peptide derived from a sequence found in gastric juice.

5 mg vial · Once daily, subcutaneous (some reports split it into two injections)

TB-500

Thymosin beta-4 fragment

TB-500 is a synthetic version of a region of the naturally occurring protein thymosin beta-4.

5 mg vial · Once daily, subcutaneous (a weekly loading pattern is also reported)

BPC-157 + TB-500 20 mg Blend

Tissue-repair research blend (BPC-157 + TB-500)

This blend combines BPC-157 and TB-500 in a single vial (20 mg by default, with a 10 mg size also listed), a common pairing in recovery-oriented research because the two peptides are studied for complementary roles in tissue-repair research.

20 mg vial · Once daily, subcutaneous
