Gonadorelin Dosage Calculator & Chart

1Set Up Your Mix

0.667 mg/mL · 667 mcg/mL

1. Pick your peptide

2. How much peptide is in the vial? It's printed on the label — usually something like 5 mg

3. How much water are you adding? More water makes each dose easier to measure

4. How much do you want per dose?

Your Answer — Gonadorelin

2 mg in 3 mL

0.15That's This Many mL

20Doses In The Vial

2 mg ÷ 3 mL = 0.667 mg/mL → 100 mcg ÷ 0.667 mg/mL = 0.15 mL → × 100 = 15 units

Looks good. Draw to 15 units on a 1 mL syringe. That is an easy amount to measure, and this vial gives you 20 doses.

Where this plan came from

Built from this peptide's dose range

Where this came from: Built from the doses listed for this peptide below — start at the lowest and step up, using the studies cited on this page. Nobody publishes a week-by-week plan for this peptide, so we built one: the doses are the researched ones shown below, and we simply put them in order from lowest to highest. Treat it as a starting point, not an official schedule.

Common Questions — Gonadorelin

How much bacteriostatic water do I add to a 2 mg vial of Gonadorelin?

Adding 3 mL of bacteriostatic water to a 2 mg vial gives 0.667 mg/mL. That is the mix every number on this page is worked out from — change the water figure in the calculator and all the draw amounts update.

What dose of Gonadorelin is used in research?

Published and reported figures for Gonadorelin run from 100 mcg to 200 mcg, typically 2× weekly. This site lists each figure with the source it came from rather than giving a single recommended number.

How many units on the syringe is a 100 mcg dose of Gonadorelin?

At 0.667 mg/mL, a 100 mcg dose is 15 units on a 1 mL U-100 insulin syringe. One vial at that mix gives about 20 doses.

How strong is the evidence behind these Gonadorelin doses?

Gonadorelin is graded clinical. Human trial or approved-label dosing has been published for this compound. We grade every compound on this site so you can weigh the numbers accordingly — the full method is on our editorial policy page.
