How many units of Hexarelin should I draw?

It depends on your vial size, BAC water, and dose. For a 2mg vial with 2mL BAC water, a beginner dose of 100mcg is typically 10 units on a U-100 syringe. Use the calculator above for your exact numbers.

How much BAC water should I add to Hexarelin?

The standard amount is 2mL of bacteriostatic water for a 2mg 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 Hexarelin vial last?

At a beginner dose of 100mcg daily, a 2mg vial lasts about 20 doses. The calculator shows exact doses per vial for your selected tier.

What syringe should I use for Hexarelin?

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.

At a 200mcg dose: 50% = 100mcg remaining after 1h. 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.

Note: Most potent GHRP for raw GH release. Raises cortisol and prolactin more than other GHRPs. Desensitization can occur — cycle 4 weeks on, 2-4 weeks off. Best on empty stomach.

About Hexarelin

Hexarelin is the most potent growth hormone releasing peptide (GHRP) available, producing the largest GH pulse of any secretagogue. It works by mimicking ghrelin at the pituitary and hypothalamus. However, it also significantly raises cortisol and prolactin — more than GHRP-2 or GHRP-6 — and is prone to desensitization with continuous use. It's best used in short cycles for maximum GH output, stacked with a GHRH for amplified GH output.
