GHRP-6 dosage calculator
A reconstitution calculator preloaded with an example GHRP-6 vial size. Enter your own vial mass, diluent, and dose to get concentration, draw volume, and insulin-syringe units. Arithmetic only - it does not tell you what dose to use.

Your vial
Printed on the vial. There is no standard size - enter what yours says.
This changes how much you draw - never how many doses the vial holds.
100 units per mL. 1 unit = 0.01 mL. This is what almost every insulin syringe sold is, in every barrel size.
Capacity only. A 1 mL U-100 syringe holds 100 units - the scale decides that, not the barrel.

What GHRP-6 dosing actually looks like
GHRP-6 has no approved product, so there is no approved dose. The protocol community dosing guides most often describe is 100-300 mcg by subcutaneous injection, 2 to 3 times daily on an empty stomach, for an 8-12 week cycle with a 4-week break - common practice, not trial-established. The published human studies I could verify were all intravenous and supervised: a pharmacokinetic study gave nine healthy men a single bolus of 100, 200 or 400 micrograms per kilogram, and two stroke trials gave hospital patients 3.5 or 5 mg twice daily for 7 days, always combined with epidermal growth factor (EGF). A separate aged-rat study used a chronic twice-daily dose, but that is an animal dose in a different species. No study establishes a repeated subcutaneous human dosing schedule. Read the full breakdown on theGHRP-6 dosage page.
Common questions
What is a typical GHRP-6 vial size?
Research-sold GHRP-6 is commonly listed in 5 mg vials, and 2 mg and 10 mg vials are also sold. This calculator preloads 5 mg as an example vial size only - it is not a recommendation, and it does nothing to verify what is actually in any vial you own.
What dose does the calculator start with, and why?
It starts at 100 mcg, the low end of the 100-300 mcg range community dosing guides most often describe - common practice, not trial-established, and not a recommendation. With the preset 5 mg vial and 2 mL of water (2,500 mcg per mL), 100 mcg is 0.04 mL, or 4 units on a U-100 syringe. The published human studies used supervised intravenous doses instead - see the GHRP-6 dosage page for the details.
What is the common GHRP-6 dose?
Community dosing guides most often describe 100-300 mcg by subcutaneous injection, 2 to 3 times daily on an empty stomach, spaced at least 3-4 hours apart, for an 8-12 week cycle with a 4-week break - often starting at 100 mcg and titrating up. That is common practice, not trial-established: no trial or regulator has set a GHRP-6 dose.
Is there an FDA-approved GHRP-6 dose?
No. GHRP-6 has no FDA-approved product and no dose established as safe or effective by any regulator. FDA lists it as a Category 2 compounding safety risk. The calculator performs arithmetic on numbers you enter; it does not know what dose is appropriate.
What is the half-life of GHRP-6, and does that affect the calculator?
One pharmacokinetic study reported an elimination half-life of about 2.5 hours after a single intravenous dose. This reconstitution calculator does not use half-life - it only converts vial mass, diluent, and dose into concentration, draw volume, and syringe units.
Where can I read what the GHRP-6 study actually used?
The GHRP-6 dosage page covers the published human studies I could verify - a pharmacokinetic study (a single IV bolus of 100, 200 or 400 mcg/kg in 9 healthy men) and two stroke trials (3.5 or 5 mg IV twice daily for 7 days, always combined with EGF) - and a chronic aged-rat study, each attributed to its source.
