Step 1 of 4
This vial holds 2,000 mcg in total.
U-100 insulin syringe · 1 mL · lines every 2 units · 1 unit = 0.01 mL
20.0 units on a U-100 insulin syringe · 1 mL · lines every 2 units, which is 0.20 milliliters. The draw lands on a syringe line.

PEG-MGF is a short piece of a growth factor your muscle makes for itself after hard exercise. A polyethylene glycol chain is attached to it, to slow down how fast it clears. It is sold for muscle repair and growth after training.
Nobody has given it to a person in a study. The human research here biopsies muscle and measures what the body makes on its own. Even that research disagrees about whether training raises it at all. The only work on the peptide went onto cultured cells and mice, using a fragment with no glycol chain on it.
No completed controlled human trial has shown which dose works for PEG-MGF. The range people report using is not a study result, tested schedule or recommendation.
no human dose shown to work
Each row starts with the same 2 mg vial and changes only the amount of water. More water makes the mixture less concentrated, so the same dose uses more syringe units.
| Water added | Concentration | Per U-100 unit | Draw for 200 mcg | Nearest syringe line |
|---|---|---|---|---|
| 1 mL | 2.00 mg/mL | 20.0 mcg | 10.0 u · 0.100 mL | exactly 10 u |
| 2 mL | 1.00 mg/mL | 10.0 mcg | 20.0 u · 0.200 mL | exactly 20 u |
| 3 mL | 0.67 mg/mL | 6.7 mcg | 30.0 u · 0.300 mL | exactly 30 u |
The vial, water and dose shown here are the calculator’s starting example for PEG-MGF. Replace them with your own values. Every result in the table is calculated from those inputs.
One vial size and three water volumes here, and the conventional draw lands exactly on a syringe line at all three. That is rarer than it sounds, and it changes what the mixing choice is about.
Most compounds here have at least one vial-and-water pairing that drops the draw between two marks. This page has none. Every combination puts the conventional amount on a whole number of units.
So the water volume is not deciding whether the number can be read. It decides how many doses the mixed vial covers, and how much liquid goes under the skin each time.
The PEG in the name is a chain attached to the peptide to slow how fast the body clears it. That chain has mass of its own, and it is part of what the vial weighs.
No label a buyer sees says how much of a labeled milligram is chain and how much is peptide. The degree of attachment varies too. This page divides the number on the vial. It cannot see inside it.
No trial has studied the attached version or the natural fragment it derives from. The human research here measures the protein muscle makes on its own in biopsied tissue, which is a different experiment from injecting anything.
The research does not agree on whether exercise raises it, and no human dose has been established.
That no dose has been published for this peptide is already on the page. Less obvious is that there is no settled convention either. One review writes down what people do. It prints this compound’s amount twice, at two different rhythms, and calls its own sources contradictory.
The same quantity appears as a few times a week, and then again as a daily amount. The review does not choose between them. It says the material it collected is internally inconsistent, which is a rare thing to admit in print.
The reported pattern names two sites. Under the skin, or into muscle. Those are not the same injection, and the amount is printed once for both.
Some records on this site carry four strengths, or two an order of magnitude apart. This one carries a single size, and every seller sampled listed it.
A formulation choice leaves the molecule alone and changes what surrounds it. Attaching a polyethylene glycol chain does not do that. It builds something else.
FDA lists this peptide among substances nominated for compounding and later withdrawn. The agency describes that group as having sat in a category for significant safety risk.
Mix 2 mg into 2 mL and one U-100 unit carries 10.0 mcg. The table shows how much peptide is in each numbered syringe line. These are conversion examples, not suggested doses.
| U-100 line | Volume | Mass (mcg) | Mass (mg) |
|---|---|---|---|
| 10 u | 0.10 mL | 100 mcg | 0.1 mg |
| 20 u | 0.20 mL | 200 mcg | 0.2 mg |
| 30 u | 0.30 mL | 300 mcg | 0.3 mg |
| 40 u | 0.40 mL | 400 mcg | 0.4 mg |
| 50 u | 0.50 mL | 500 mcg | 0.5 mg |
| 60 u | 0.60 mL | 600 mcg | 0.6 mg |
| 70 u | 0.70 mL | 700 mcg | 0.7 mg |
| 80 u | 0.80 mL | 800 mcg | 0.8 mg |
| 90 u | 0.90 mL | 900 mcg | 0.9 mg |
| 100 u | 1.00 mL | 1,000 mcg | 1 mg |
