Frequently Asked
How do I reconstitute GHRP-6?
Add 2 mL of bacteriostatic water to a 5 mg vial, injecting slowly down the inside wall. Swirl gently; never shake. This yields a concentration of 2500 µg/mL.
What is the recommended dose of GHRP-6?
A typical research dose is 100 µg. Consult the ASCEND calculator for your specific vial concentration and draw volume.
How many doses are in a GHRP-6 vial?
A 5 mg vial reconstituted with 2 mL BAC water yields approximately 50 doses at 100 µg each.
How many IU is 100 µg of GHRP-6 on a syringe?
With a 5 mg vial reconstituted in 2 mL bacteriostatic water, the concentration is 2500 µg/mL. For a 100 µg dose: Volume = 100 µg ÷ 2500 µg/mL = 0.04 mL. Draw to the 4 line on a 100-unit insulin syringe. You can adjust these values in the ASCEND calculator for any vial size.
What does a GHRP-6 dosage calculator do?
A GHRP-6 dosage calculator converts your vial size and BAC water volume into an exact syringe draw in IU. Enter your vial strength (5 mg), reconstitution volume (2 mL), and target dose to get the precise line to draw on an insulin syringe.
What is the GHRP-6 reconstitution calculator formula?
Draw volume (mL) = Dose (µg) divided by Concentration (µg/mL). For a 5 mg vial with 2 mL BAC water: concentration = 2500 µg/mL. For a 100 µg dose, the ASCEND calculator gives the exact IU line on your syringe instantly.
Peptide Intelligence
What is the half-life of GHRP-6?
GHRP-6 has a short half-life of approximately 15–60 minutes, requiring 2–3 daily subcutaneous injections. Its strong appetite stimulation via ghrelin mimicry distinguishes it from more selective GHRPs like Ipamorelin.
Why does GHRP-6 cause such strong appetite stimulation?
GHRP-6 has high affinity for the ghrelin receptor (GHS-R1a) and significantly elevates circulating ghrelin. Ghrelin is the primary hunger-stimulating hormone, acting on the hypothalamus. This appetite stimulation is sometimes used intentionally in mass-building research protocols.
What is the GI protective effect of GHRP-6?
GHRP-6 has been studied for gastroprotective effects partly through its ghrelin activity. Ghrelin receptors are expressed throughout the GI tract, and GHRP-6 may protect against mucosal damage and improve gastric motility in research models.
