This vial holds 5,000 mcg in total.
U-100 insulin syringe · 1 mL · lines every 2 units · 1 unit = 0.01 mL
4.0 units on a U-100 insulin syringe · 1 mL · lines every 2 units, which is 0.04 milliliters. The draw lands on a syringe line.

Hexarelin is a peptide six amino acids long, built in the early 1990s to trigger a growth-hormone pulse. Sellers pitch it as the hardest-hitting of the growth-hormone peptides, for muscle and recovery.
The pulse gets smaller as the doses repeat. On the only long course on record it had roughly halved by week 16, and came back only once the drug stopped. No trial turned that into a schedule, and none measured muscle.
Each row starts with the same 5 mg vial and changes only the amount of water. More water makes the mixture less concentrated, so the same dose uses more syringe units.
| Water added | Concentration | Per U-100 unit | Draw for 100 mcg | Nearest syringe line |
|---|---|---|---|---|
| 1 mL | 5.00 mg/mL | 50.0 mcg | 2.0 u · 0.020 mL | exactly 2 u |
| 2 mL | 2.50 mg/mL | 25.0 mcg | 4.0 u · 0.040 mL | exactly 4 u |
The vial, water and dose shown here are the calculator’s starting example for Hexarelin. Replace them with your own values. Every result in the table is calculated from those inputs.
Hexarelin’s vials hold little powder, and the conventional dose is small on top of that. The two together put nearly every reading on this page in single figures of units, which is where rounding does the most damage.
Across this page’s vial sizes and water volumes, the conventional amount reads in the low single digits of units almost everywhere. At that size one mark is a quarter or a third of the draw.
One pairing does better. The smaller vial with the larger water volume is the only combination here that reaches double figures. That alone is a reason to choose it.
In the only long course on record, the growth-hormone response had roughly halved by week sixteen. It recovered after stopping.
That shapes vial planning more than the arithmetic does. The evidence describes a course with an end, not an open schedule. Counting doses per vial against an endless interval describes something the studies did not do.
None of the human quantities on this page becomes a draw on its own. Each one needs a body weight to multiply by, because none of them was a flat figure.
The flat microgram numbers circulating for hexarelin are practice rather than published amounts. The human work also found the curve flattening while other hormones kept climbing. Going higher buys something nobody was aiming for.
Most records in this file were studied in a vein and are sold for the skin. Hexarelin is the exception, and only halfway. The long course and the same-day schedule were both injected under the skin. What does not carry across is the basis of the number.
Two of the three studies on this page injected under the skin. The third pushed a dose into a vein. Its job was to map where the response curve flattens, not to treat anyone.
One study here compared two injections in a day against three. It sampled hormones right through the day and into the night.
Two strengths are generated here. A third turns up in listings. When this page was built nobody could find a seller behind it, and the listings were other people’s calculators.
FDA named the acetate salt in a warning letter to a broker that sells ingredients. The letter placed the salt among substances the agency treats as off-limits for compounding into medicines for people.
Mix 5 mg into 2 mL and one U-100 unit carries 25.0 mcg. The table shows how much peptide is in each numbered syringe line. These are conversion examples, not suggested doses.
| U-100 line | Volume | Mass (mcg) | Mass (mg) |
|---|---|---|---|
| 10 u | 0.10 mL | 250 mcg | 0.25 mg |
| 20 u | 0.20 mL | 500 mcg | 0.5 mg |
| 30 u | 0.30 mL | 750 mcg | 0.75 mg |
| 40 u | 0.40 mL | 1,000 mcg | 1 mg |
| 50 u | 0.50 mL | 1,250 mcg | 1.25 mg |
| 60 u | 0.60 mL | 1,500 mcg | 1.5 mg |
| 70 u | 0.70 mL | 1,750 mcg | 1.75 mg |
| 80 u | 0.80 mL | 2,000 mcg | 2 mg |
| 90 u | 0.90 mL | 2,250 mcg | 2.25 mg |
| 100 u | 1.00 mL | 2,500 mcg | 2.5 mg |
