Reconstitution chart: 5 mg vial
| BAC water added | Concentration | Draw for 100 mcg dose | Draw for 200 mcg dose |
|---|---|---|---|
| 1 mL | 5,000 mcg/mL | 2 units | 4 units |
| 1.5 mL | 3,333 mcg/mL | 3 units | 6 units |
| 2 mL | 2,500 mcg/mL | 4 units | 8 units |
| 2.5 mL | 2,000 mcg/mL | 5 units | 10 units |
Draws are U-100 insulin syringe units (100 units = 1 mL). Formula: dose in mcg ÷ (vial mcg ÷ water mL) × 100. The calculator above handles any other combination.
About Hexarelin
Hexarelin is a synthetic growth hormone secretagogue in the same family as the GHRP peptides: it mimics ghrelin at its receptor to prompt a pulse of growth hormone from the pituitary. It is one of the more potent compounds in the class, and that potency comes with a known catch, which is that the growth hormone response tends to fade with continued use as receptors desensitize. It has no regulatory approval.
Community protocols typically discuss 100 mcg per injection, one to three times daily, often timed before bed or around training. The desensitization issue is why discussion frequently includes cycling on and off rather than running it continuously. Note the unit: micrograms. A 5 mg vial holds 5,000 mcg, so at 100 mcg per dose one small vial covers fifty injections. As everywhere on this site, those figures describe community practice, not a recommendation.
Because the doses are tiny relative to the vial, the water you add is about readability. With 1 mL of BAC water in a 5 mg vial, a 100 mcg dose is only a 2 unit draw, too small to measure with confidence. Stretch the water to 2.5 mL and the same dose becomes 5 units. The calculator flags any draw under 3 units so you are never eyeballing a sliver of a syringe, and it warns if the unit toggle looks wrong, since mg instead of mcg is a 1,000x error here. Refrigerate after mixing.
Quick facts
- Status: no regulatory approval
- A potent ghrelin-mimicking growth hormone secretagogue; response can fade with continued use
- Communities discuss 100 mcg, one to three times daily, often cycled
- Common vial sizes: 2, 5, and 10 mg
Stop gambling on where you buy your peptides.
The calculator tells you how much to draw. The Verified Buyer's Manual tells you how to source the peptide itself without getting scammed or shipped underdosed product. Trace any compound back to the lab that made it, read a Certificate of Analysis and catch a fake, grade any seller before you pay, and price it right. A repeatable system, not a list of names that goes stale.
- How to read a lab report (COA) and spot a faked or misattributed one
- Source tracing: find verified sellers yourself from public test data
- The vetting grid: a yes-or-no scorecard for any seller
- Real cost-per-mg math so you never overpay
- Reconstitution, storage, and the first 72 hours after a package lands
