Gonadorelin Dosage Calculator & Research Doses

1Set Up Your Mix

0.8 mg/mL · 800 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?

All answers assume a standard 1 mL U-100 syringe, where 1 unit = 0.01 mL. That is the usual insulin syringe and the one every number here is based on.

2 mg ÷ 2.5 mL = 0.8 mg/mL → 200 mcg ÷ 0.8 mg/mL = 0.25 mL → × 100 = 25 units—

Looks good. Draw to 25 units on a 1 mL syringe. That is an easy amount to measure, and this vial gives you 10 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.

Native gonadotropin-releasing hormone. Pulsatile administration stimulates the axis; continuous administration paradoxically suppresses it, which is exactly why cadence matters more than dose here.
