0102030405060708090100 U-100 syringe · 1 mL · 100 units draw to 3
10 mg ÷ 3 mL = 3.333 mg/mL  →  100 mcg ÷ 3.333 mg/mL = 0.03 mL  →  × 100 = 3 units
Looks good. Draw to 3 units on a 1 mL syringe. That is an easy amount to measure, and this vial gives you 100 doses.
When to dose
Time of dayBefore bed, or first thing in the morning — not during the day.
FoodFasted. Nothing to eat for about 2 hours before, and wait 20–30 minutes after.

Food, and carbohydrate in particular, raises insulin and blunts the growth-hormone pulse these compounds are meant to trigger. The two windows where you are naturally fasted and GH release is highest are early sleep and first thing on waking, which is why those are the only two sensible times.

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 — GHRP-6

How much bacteriostatic water do I add to a 10 mg vial of GHRP-6?

Adding 3 mL of bacteriostatic water to a 10 mg vial gives 3.33 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 GHRP-6 is used in research?

Published and reported figures for GHRP-6 run from 100 mcg to 300 mcg, typically 1–3× daily. 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 GHRP-6?

At 3.33 mg/mL, a 100 mcg dose is 3 units on a 1 mL U-100 insulin syringe. One vial at that mix gives about 100 doses.

How strong is the evidence behind these GHRP-6 doses?

GHRP-6 is graded preclinical. Laboratory and animal data only. No human dosing trials have been published. We grade every compound on this site so you can weigh the numbers accordingly — the full method is on our editorial policy page.
