How many units of GHRP-6 should I draw?

It depends on your vial size, BAC water, and dose. For a 5mg vial with 2mL BAC water, a beginner dose of 100mcg is typically 4 units on a U-100 syringe. Use the calculator above for your exact numbers.

How much BAC water should I add to GHRP-6?

The standard amount is 2mL of bacteriostatic water for a 5mg vial. More water gives a more dilute solution — easier to measure small doses. Less water means fewer injections per vial. Adjust the BAC water slider in the calculator to see how it changes your syringe units.

How long does a GHRP-6 vial last?

At a beginner dose of 100mcg daily, a 5mg vial lasts about 50 doses. The calculator shows exact doses per vial for your selected tier.

What syringe should I use for GHRP-6?

Most people use a U-100 insulin syringe (1mL / 100 units). For very small doses, a U-50 or U-30 syringe gives better precision. The calculator adjusts units automatically for whichever syringe you pick.

GHRP-6 Pharmacokinetics

Pharmacokinetics — Active Dose Over Time

t½ = ~20 min

After 1 half-life (20m): 50% remainsAfter 2 half-lives (40m): 25% remainsAfter 3 half-lives (1h): 12.5% remains

At a 200mcg dose: 50% = 100mcg remaining after 20m. Recommended frequency: 2x Daily.

Disclaimer: This curve is a simplified first-order exponential decay model. Actual pharmacokinetics vary based on injection site, individual metabolism, body composition, and other factors. Half-life values are approximate and based on available preclinical and clinical literature. Many research peptides lack formal human pharmacokinetic studies.

GHRP-6 Dosing Protocol

Level	Dose / Injection	Frequency
Beginner	100mcg	Daily
Moderate	200mcg	2x Daily
Aggressive	300mcg	3x Daily

Note: Strongest GH pulse among GHRPs. Dramatically increases appetite via ghrelin mimicry. Best for mass gaining protocols. Take on empty stomach 20-30 min before meals.

About GHRP-6

GHRP-6 (Growth Hormone Releasing Peptide-6) is one of the most potent GH secretagogues available. It works by mimicking ghrelin, the hunger hormone, which triggers a strong growth hormone pulse from the pituitary. Unlike Ipamorelin, GHRP-6 significantly increases appetite and raises cortisol and prolactin slightly. This makes it ideal for mass-gaining protocols where increased caloric intake is desired.
