GLOW Peptide Dosage Chart and Blend Calculator
GLOW peptide dosage chart figures are vial math, because no human dose exists for this blend. GLOW puts GHK-Cu, BPC-157 and TB-500 in one vial. On 6 of the 8 pages we could read, it is a 70 mg vial: 50 mg GHK-Cu plus 10 mg of each of the other two. The chart below shows what one syringe unit holds once you add bacteriostatic (bac) water.
Short answer for a 70 mg GLOW vial
What one unit holds depends on the water you add. More water spreads the same 70 mg thinner, so each unit holds less of every part. The chart below lists the micrograms per unit at four water volumes, and the calculator works it out for your own vial.
6 of the 8 GLOW pages we read split one draw at one water volume for one vial. This page does the split per unit for every vial size we found, and the calculator below does it for yours. For what the research says about each part, read our KLOW vs GLOW evidence guide.

Disclaimer: the tool only multiplies and divides what you type, so it never sets a dose. GLOW as a mix has no human trial, and a licensed clinician makes any dose call.
The math trusts the label split and the water you typed. A real vial can hold more or less.
Work backwards from one part
Pick a part and type an amount in mcg. This field starts empty; the calculator does not suggest one.
The starting values are the community split and fill from the chart below. For a single peptide, use the GHK-Cu calculator or the peptide reconstitution calculator.

GLOW peptide dosage chart: mcg per unit by water volume
The water you add sets how much of each part sits in one unit. The vial still holds the same 70 mg. We built this table ourselves. Method: each part in mg, times 1000, divided by the water in mL, divided by 100 units per mL.
Using the 70 mg split from the GLOW guide on peptidedosingprotocols.com, a community dosing site, our script gives these amounts in one unit:
| Bac water | Blend per mL | GHK-Cu | BPC-157 | TB-500 | All three | 10-unit draws per vial |
|---|---|---|---|---|---|---|
| 1 mL | 70 mg | 500 mcg | 100 mcg | 100 mcg | 700 mcg | 10 |
| 2 mL | 35 mg | 250 mcg | 50 mcg | 50 mcg | 350 mcg | 20 |
| 3 mL | 23.33 mg | 166.7 mcg | 33.3 mcg | 33.3 mcg | 233.3 mcg | 30 |
| 5 mL | 14 mg | 100 mcg | 20 mcg | 20 mcg | 140 mcg | 50 |
Disclaimer: these numbers turn a vial label into micrograms per syringe unit. They are not a dose for anyone, and no human study has tested the GLOW blend.
GHK-Cu is always five times the BPC-157 or TB-500 in each unit. Water cannot change that. Only a different vial split can.

Which GLOW vial do you have? What we found on 23 October 2026
GLOW has no official recipe, so we checked what pages say it holds. On 23 October 2026 we tried 23 public GLOW pages from US search results. We could read 8 that describe the blend. The rest were removed, blocked or empty. We only read them, and bought nothing.
- 6 of 8 named a 70 mg vial with GHK-Cu, BPC-157 and TB-500 at 50, 10 and 10 mg.
- 2 of 8 described a 42 mg vial: 27 mg GHK-Cu, 5 mg BPC-157 and 10 mg TB-500. One of them still called it a 5 to 1 to 1 ratio, which those numbers are not.
- 1 page listed a 30 mg vial with 10 mg of each, and 1 mentioned a 90 mg size.
- 6 of 8 gave the amount of each part in a draw. Only 3 of 8 said plainly that no trial has tested the blend.
That is our own snapshot, not a survey of every seller. It shows why the label matters more than the name.
Using the splits printed on the pages in our 23 October 2026 snapshot, one unit from each vial mixed with 3 mL holds:
| Vial (GHK-Cu, BPC-157, TB-500) | Pages | GHK-Cu | BPC-157 | TB-500 | All three |
|---|---|---|---|---|---|
| 70 mg (50, 10, 10) | 6 of 8 | 166.7 mcg | 33.3 mcg | 33.3 mcg | 233.3 mcg |
| 42 mg (27, 5, 10) | 2 of 8 | 90 mcg | 16.7 mcg | 33.3 mcg | 140 mcg |
| 30 mg (10, 10, 10) | 1 of 8 | 33.3 mcg | 33.3 mcg | 33.3 mcg | 100 mcg |
Disclaimer: these numbers turn a vial label into micrograms per syringe unit. They are not a dose for anyone, and no human study has tested the GLOW blend.
The same draw can hold very different amounts. In the 42 mg vial, BPC-157 per unit is half what the 70 mg vial gives. In the 30 mg vial, GHK-Cu per unit is one fifth.

What is the usual GLOW dose people cite?
No human dose has been published for the GLOW blend. The figure online comes from community practice. The top result for this search describes it this way, and says no human trial has tested the three together.
The GLOW guide on peptidedosingprotocols.com, a community dosing website, describes (community practice, not a trial):
70 mg vial (50 mg GHK-Cu, 10 mg BPC-157, 10 mg TB-500) mixed with 3 mL of bac water
10 units once a day under the skin, about 2.33 mg of blend
In that draw: about 1.67 mg GHK-Cu and 0.33 mg each of BPC-157 and TB-500
Disclaimer: this is community practice copied from a dosing website. It is not from a trial and not advice to take any amount. No human dose has been published for the GLOW blend.
A unit count only means something next to its water volume. If a page says 10 units but you mixed with 2 mL, the same 10 units holds 1.5 times as much. Check the chart above, or type both numbers into the calculator.

Is there human dose data for any GLOW ingredient?
Only BPC-157 has any, and it is very thin. A 2025 review counted three human pilot studies in total. A 2025 systematic review found 36 studies, of which 35 were preclinical. Two of the pilots name an amount:
Two small BPC-157 pilot studies, each with no control group, report these amounts (trial details, BPC-157 alone):
Interstitial cystitis pilot (2024): 10 mg in total, injected around the bladder wall in one procedure, 12 women
IV safety pilot (2025): 10 mg by vein on the first day and 20 mg on the second, 2 adults
Disclaimer: these are study details for BPC-157 given alone, by other routes, in tiny groups. They are not a GLOW dose and not advice to take any amount.
- TB-500: no human dose has been published. The FDA reports no data at all on people exposed to the TB-500 fragment.
- GHK-Cu: no human injection dose has been published that we could find. The FDA notes limited human data for injected GHK-Cu.
- The blend: no study of the three given together was found.
Neither pilot used a shot under the skin, and neither used a blend. So their numbers cannot be read as GLOW amounts. Each ingredient has its own profile: GHK-Cu, BPC-157 and TB-500.

How do you check GLOW math by hand?
Four steps are enough. We ran the calculator against these steps and the chart on 23 October 2026, and they matched at 1, 2, 3 and 5 mL.
Worked example, using the community figure from the section above (community practice, not a trial):
Strength: 70 mg divided by 3 mL is 23.33 mg per mL
Draw: 10 units is 0.1 mL, so it holds about 2.33 mg of blend
GHK-Cu: 50 mg times 1000, divided by 3 mL, times 0.1 mL, is 1666.7 mcg
BPC-157 and TB-500: 10 mg each, the same way, is 333.3 mcg each
Disclaimer: this is community practice copied from a dosing website. It is not from a trial and not advice to take any amount. No human dose has been published for the GLOW blend.
Run it backwards to be sure. Add the three parts and you get back the blend amount in the draw. Our insulin syringe units chart shows how each unit mark maps to mL.

How much bac water for GLOW, and for a 10 mg vial?
No label says how much water GLOW needs, because GLOW has no approved label. The pages we read named volumes from 1 mL up to 12 mL, and 3 mL came up most. Less water makes small draws. More water makes each draw bigger and easier to read, but a 1 mL syringe holds only 100 units.
A plain 10 mg vial of any one peptide follows the same rule. With the U-100 scale from MedlinePlus, 100 units to 1 mL, it works out to these amounts in one unit:
| Bac water | mg per mL | mcg in 1 unit |
|---|---|---|
| 1 mL | 10 | 100 |
| 2 mL | 5 | 50 |
| 3 mL | 3.33 | 33.3 |
Disclaimer: these numbers turn a vial label into micrograms per syringe unit. They are not a dose for anyone, and no human study has tested the GLOW blend.
Bac water carries benzyl alcohol as a preservative and comes in a multiple-dose vial, per its label. Read what bac water is and how to use peptides for the mixing steps.

How is GLOW stored, and is it safe?
No maker label sets a shelf life for mixed GLOW. Five of the 8 pages we read said to keep it cold once mixed. That is their advice, not a label. Our FAQ on whether bac water needs the fridge covers what the water label says.
Safety in people has not been shown for the blend or for TB-500. The FDA warns that compounded BPC-157, GHK-Cu and TB-500 may trigger immune reactions, partly from impurities. The 2025 systematic review found no clinical safety data for BPC-157. GLOW is sold for research use only. When we checked openFDA that same day, none of the three had an approved product.

Common questions
How do you reconstitute a GLOW peptide vial?+
Add bac water to the powder, then swirl gently until it is clear. The volume is your choice, and it only changes the strength per mL. The chart below gives that strength at four water volumes. No drug label exists for GLOW, so no official mixing volume exists either.
How much bac water do you use to reconstitute 10 mg?+
Any volume works for the math. More water means bigger draws for the same amount, and less water means smaller ones. The 10 mg table in the mixing section below lists what one unit holds at 1, 2 and 3 mL.
How long does GLOW peptide take to work?+
No study has measured it. No trial has tested GHK-Cu, BPC-157 and TB-500 together in people, so there is no timeline to report. Any week count you see for the blend comes from sellers or users, not research.
What does 10 units of GLOW contain?+
That changes with the vial and the water. The same draw from a 42 mg vial holds far less than one from a 70 mg vial at the same water. The worked example in the check the math section shows what that draw holds in a 70 mg vial, with its source.
Is GLOW approved or tested?+
No. GLOW is a seller name for a blend, and openFDA showed no approved product for any of its three parts when we checked on 23 October 2026. The FDA reports no human exposure records for TB-500, and only limited human data for injected GHK-Cu. A 2025 review counted only three human pilot studies of BPC-157.
