Enter vial size and bacteriostatic water volume to get concentration, syringe units and doses per vial — or read the Ipamorelin peptide guide for what the compound is.
A 10 mg vial of Ipamorelin reconstituted with 5 mL of bacteriostatic water gives a concentration of 2 mg/mL, or 20 mcg per unit on a U-100 syringe. For a 200 mcg dose, draw the syringe to 10 units (0.10 mL). At that dose the vial provides about 50 doses.
Draw the syringe up to
That's one 200 mcg dose. Add 1 mL of water to your 5 mg vial first.
| Step | Dose | Draw on a U-100 | Doses per vial |
|---|---|---|---|
| Low | 100 mcg | 2 units | 50 |
| Standard | 200 mcg | 4 units | 25 |
| Upper stated range | 300 mcg | 6 units | 16 |

Ipamorelin draw volumes depend entirely on the concentration you mixed. At the page default of 2 mg/mL, the whole stated range fits comfortably in the readable part of a U-100 barrel: 100 mcg is 5 units, 200 mcg is 10 units and 300 mcg is 15 units. Nothing in the ipamorelin range comes close to exceeding a 1 mL barrel — the opposite of the GLP-1 calculators, where the failure mode is a draw too large. Here the failure mode is a draw too small to read.
| Protocol | Amount | Frequency | Draw at 2 mg/mL | Volume | Daily total |
|---|---|---|---|---|---|
| Low | 100 mcg | Once daily | 5 units | 0.05 mL | 100 mcg |
| Standard (page default) | 200 mcg | Once daily | 10 units | 0.10 mL | 200 mcg |
| Upper stated range | 300 mcg | Once daily | 15 units | 0.15 mL | 300 mcg |
| Split | 100 mcg + 100 mcg | Twice daily (morning + night) | 5 units per injection | 0.05 mL each | 200 mcg |
Low: 100 mcg once daily — draw 5 units (0.05 mL) at 2 mg/mL. Standard: 200 mcg once daily — draw 10 units (0.10 mL) at 2 mg/mL. Upper stated range: 300 mcg once daily — draw 15 units (0.15 mL) at 2 mg/mL. Split: 100 mcg morning and 100 mcg night — draw 5 units (0.05 mL) for each injection at 2 mg/mL. The four protocol rows are the science article's stated figures; the unit and volume columns are this page's arithmetic on the default concentration.
Ipamorelin is dosed in micrograms, and that single fact changes every reconstitution decision. A milligram-dosed compound fails by producing a draw larger than a 1 mL barrel; ipamorelin fails in the opposite direction, by producing a draw of one or two syringe units where a half-unit misread is a 25–50% dose error. The table shows the same 100 mcg dose from the same 10 mg vial at four dilutions — identical drug, four very different reading accuracies.
| 10 mg vial in | Concentration | mcg per unit | 100 mcg dose | Effect of a ½-unit misread |
|---|---|---|---|---|
| 1 mL | 10 mg/mL | 100 mcg | 1 unit | ±50 mcg — 50% of the dose |
| 2 mL | 5 mg/mL | 50 mcg | 2 units | ±25 mcg — 25% of the dose |
| 5 mL (default) | 2 mg/mL | 20 mcg | 5 units | ±10 mcg — 10% of the dose |
| 10 mL | 1 mg/mL | 10 mcg | 10 units | ±5 mcg — 5% of the dose |
All arithmetic, shown step by step: a half unit is 0.005 mL, so the mass it represents is concentration mg/mL × 0.005 × 1,000 mcg. The same 100 mcg Ipamorelin dose is 1 unit from a 10 mg vial in 1 mL and 10 units from the same vial in 10 mL — identical drug, ten times the reading resolution. For a microgram-dosed peptide a more dilute reconstitution is the accurate one, the reverse of the rule that applies to milligram-dosed GLP-1 compounds. Why label mass and delivered mass diverge in the first place: why 10 mg isn't 10 mg.
Ipamorelin reconstitution is a choice, not a recipe — no label sets a diluent volume, so the volume you pick is the one that puts your intended dose in a readable part of the syringe.
Step 1 — Choose BAC water volume. For the stated 100–300 µg/day range in a readable draw, target 2 mg/mL — for example, 5 mL of bacteriostatic water into a 10 mg vial, or 2.5 mL into a 5 mg vial. Volumes below 2 mL on a 10 mg vial push a 100 mcg dose under 5 units.
Step 2 — Reconstitute. Inject the bacteriostatic water slowly against the inside glass wall. Swirl gently; do not shake. The solution should be clear and colourless. See reconstituting peptides step by step and the bacteriostatic water guide.
Step 3 — Store. Refrigerate at 2–8 °C.
Our blend calculator applies a 28-day stability window to a reconstituted CJC-1295 + ipamorelin vial. No approved label sets an in-use period for standalone ipamorelin and no stability data on the ipamorelin fact base covers one, so treat 28 days as a working convention carried over from the blend page rather than a measurement on this compound. Flagged for editorial resolution, September 2026.
An Ipamorelin vial lasts as many days as the label mass divided by the daily amount — water volume changes nothing about it. At the page default, a 10 mg vial at 200 mcg daily is fifty days. At the stated daily range every tracked vial size except the smallest outlasts the 28-day window our blend calculator applies, so vial size on this compound is a storage decision before it is a price decision.
| Vial size | At 100 mcg/day | At 200 mcg/day | At 300 mcg/day | At 300 mcg twice daily |
|---|---|---|---|---|
| 4 mg | 40 days | 20 days | ~13 days | ~7 days |
| 5 mg | 50 days | 25 days | ~17 days | ~8 days |
| 10 mg (default) | 100 days | 50 days | ~33 days | ~17 days |
| 12 mg | 120 days | 60 days | 40 days | 20 days |
A 10 mg vial of Ipamorelin at 200 mcg once daily lasts about 50 days. A 4 mg vial at 200 mcg once daily lasts about 20 days. A 12 mg vial at 100 mcg once daily lasts about 120 days. A 5 mg vial at 300 mcg once daily lasts about 17 days. Only the 4 mg vial at 200 mcg/day and the 5 mg vial at 300 mcg/day fall inside 28 days at the stated range. Since no in-use period is established for standalone ipamorelin, this table cannot tell you to discard at day 28; it can only tell you which sizes raise the question.
Ipamorelin is not approved for any medical indication anywhere in the world as of August 2026, and it is sold strictly as a research-use-only compound by third-party laboratories. It is not approved by the FDA, the EMA or the TGA. Its one distinctive regulatory fact is that ipamorelin acetate is on the FDA's active Category 2 bulk-substances list under the 503B outsourcing-facility route, not Category 1 — one of the very small number of peptides still on that active list after the April 2026 removals. In sport it is prohibited at all times.

It depends on the concentration. At the page default of 2 mg/mL (10 mg vial + 5 mL), 200 mcg is 10 units on a U-100 syringe. At 5 mg/mL it is 4 units, at 1 mg/mL it is 20 units, and at 10 mg/mL it is 2 units. A units figure quoted without a concentration cannot be used.
There is no standard volume and no label to specify one. 5 mL gives 2 mg/mL, which puts the whole 100–300 mcg range between 5 and 15 units — readable on any U-100 barrel. 1 mL gives 10 mg/mL, where a 100 mcg dose is a single unit and cannot be drawn accurately.
Our science article states a standard range of 100–300 µg per day subcutaneously, with peak IGF-1 at 200 µg/day and no added benefit above it, and a split option of 100 µg morning plus 100 µg night. No regulator has approved a dose, and no trial in this fact base tested those figures as a schedule.
At 200 mcg once daily: a 4 mg vial lasts about 20 days, a 5 mg vial about 25, a 10 mg vial about 50 and a 12 mg vial about 60. Our blend calculator applies a 28-day stability window to a reconstituted vial, so the larger sizes outlast it — no in-use period is established for standalone ipamorelin.
No. Ipamorelin is not approved for any medical indication anywhere in the world as of August 2026, and it is not approved by the FDA, the EMA or the TGA. Ipamorelin acetate is on the FDA's active Category 2bulk-substances list under the 503B outsourcing-facility route, not Category 1. It is sold research-use-only.
No. The indexed tests establish that vendors are broadly selling the correct molecule at roughly the stated quantity. A certificate confirms identity and purity; it does not confirm the amount in your particular vial, and at microgram doses a small quantity variance is a large proportional one.
