GLOW

Also known as: GLOW 70 · GLOW peptide · GLOW Stack · GLOW Blend · GHK-Cu/BPC/TB · GLOW Pen

Updated 22 sources

One vial holding GHK-Cu, BPC-157 and TB-500 at 5:1:1, 70 mg in total. GHK-Cu is about 71% of every draw, so this is a copper-peptide product with repair peptides riding along. It is a seller formulation, not a tested drug, and the name GLOW is also used loosely for copper-peptide skincare.

Quick facts

Half-life
  • No value for the blend. BPC-157 clears in under 30 minutes in rats and dogs. GHK-Cu and the TB-500 fragment have no human values; full-length thymosin beta-4 by IV is cited at 0.5 to 2.1 hours.

What people use GLOW for

  • Skin firmness, texture and anti-aging
  • Skin recovery after procedures
  • Thinning hair, sometimes with a topical GHK-Cu scalp serum
  • Light tissue repair alongside skin goals
  • In clinics, alongside PRP, microneedling and physical therapy

How it is thought to work. Each part brings its own claimed role: GHK-Cu for collagen and skin remodeling, BPC-157 for local repair, TB-500 for cell migration. None of this has been tested as a blend. For pure skin goals, several guides say GHK-Cu alone, often topical, is the closer fit.

Who should avoid it

  • Cancer historyCondition

    Listed as a reason to avoid by guides.

  • Wilson's diseaseCondition

    A copper disorder, and GHK-Cu is most of the vial.

  • Liver diseaseCondition

    Listed as a reason to avoid by guides.

  • PregnancyCondition

    Listed as a reason to avoid by guides.

  • Tested sportCondition

    BPC-157 and TB-500 are prohibited by WADA at all times.

  • KLOWSubstance

    The two overlap almost entirely; guides say run one or the other.

Storage

Powder (before mixing)

Temperature
-20 °C

Freezer at -20 C or below. Fridge at 2 to 8 C is fine short term.

Mixed vial

Temperature
2 to 8 °C
Use within
28 days

Fridge at 2 to 8 C, dark, upright, never frozen. Most guides say 28 days. One splits it by part: BPC-157 and GHK-Cu up to 30 days, TB-500 only 1 to 2 weeks. No blend stability study exists. Mixed with plain water, about 24 hours.

Mixed with: Bacteriostatic water

Mixing. 70 mg is the total, not each. 42 mg vials are listed as 27/5/10 mg by two sources and 30/6/6 mg by another; no source gives the 35 mg recipe. Light blue or blue-green is normal; discard if cloudy, green or brown.

Stacks people report

Combinations from guides and community posts, with the reason given.
  • Semaglutide

    Guides call GLOW compatible with GLP-1 drugs such as semaglutide and retatrutide.

  • CJC-1295 (no DAC) + Ipamorelin

    Described as compatible with CJC-1295 and ipamorelin; clinics also pair it with MOTS-c.

  • KPV

    Adding KPV turns GLOW into KLOW. Do not run both, since they overlap.

Evidence and legal status

Evidence: no human trials

No study of the blend in humans or animals. GHK-Cu has small human topical trials, BPC-157 limited human pilots, and the TB-500 fragment animal data only. Forum reports, such as faster recovery after hernia surgery, are single anecdotes.

FDA and WADA

Not FDA approved

An approval withdrawn, or removed from FDA's compounding lists.

Not FDA approved. The 2026-04-15 notice removed BPC-157, the TB-500 fragment and injectable GHK-Cu from 503A Category 2 because nominations were withdrawn. In July 2026 an advisory committee recommended BPC-157 and TB-500 for the 503A list (reported 8 to 6), against staff advice. GHK-Cu review is due by end of February 2027.

WADA 2026 names BPC-157 under S0 and thymosin beta-4 and its derivatives, such as TB-500, under S2.3, prohibited at all times. That makes GLOW prohibited for tested athletes. No final FDA rule was found.

WADA: Prohibited

GLOW questions

What is in GLOW?

50 mg GHK-Cu, 10 mg BPC-157 and 10 mg TB-500 in a 70 mg vial. The 70 mg is the total, not each. One site says GLOW is usually just GHK-Cu and BPC-157; every other source includes TB-500.

How much bacteriostatic water?

3 mL is the norm for a 70 mg vial. One guide uses 2 mL.

How many units per day?

10 units at 3 mL, once daily, is the consensus.

Daily or three times a week?

Both are published: 10 units daily at 3 mL, or 10 units Monday, Wednesday and Friday at 2 mL for 8 to 12 weeks.

Should I adjust by body weight?

One guide does, at 3 mL: under 55 kg 7.5 units, 55 to 85 kg 10 units, 85 to 110 kg 12 units, over 110 kg 14 units. Nobody else does.

How long should I run it?

Guides give 4 weeks then 2 to 4 off, 4 to 6 on and 2 to 4 off, or 8 to 12 on and 4 to 8 off. One says the GHK-Cu part governs cycling at 30 to 60 days on and equal time off. A seller suggests 6 to 12 weeks for skin and 4 to 6 for recovery.

Can I inject smaller doses near the target area?

A seller describes 5 to 10 units, sometimes split across small sites, judged over 4 to 8 weeks.

Can GLOW do a TB-500 loading phase?

No. The fixed ratio cannot reach 2 to 5 mg of TB-500 twice weekly. People who want that run separate vials: BPC-157 250 to 500 mcg a day, TB-500 2 to 5 mg twice weekly, GHK-Cu 1 to 2 mg a day.

How long does a vial last?

About 30 days at 10 units daily.

How much copper per shot?

About 264 mcg of elemental copper at 10 units and 395 mcg at 15 units (3 mL dilution).

Why does it sting?

The copper peptide. More water, a room-temperature vial and a slow push help.

Can I inject it into my face?

Guides say no, and point to topical GHK-Cu instead. IM injection is also called a mistake; it is a subQ product.

Can the parts share one syringe?

Sources disagree.

Who should skip it?

Guides list a cancer history, Wilson's disease, liver disease, pregnancy and tested sport.
