Ipamorelin Dosage Calculator and Chart: Timing, Cycle and the 10mg Vial

Ipamorelin is dosed in micrograms. A 10mg vial of the white freeze-dried powder holds 10,000mcg, and research protocols draw 100 to 200mcg at a time, so one vial covers 50 to 100 injections. Each injection gives one short burst of growth hormone, which is why the schedule matters as much as the amount: how many injections a day, when they land against sleep and meals, and how many weeks the run lasts.

Simms Research sells Ipamorelin as a single 10mg vial for $74, and CJC-1295 and ipamorelin together as a 10mg blend, CJC-1295 noDAC / Ipamorelin, for $78. Everything below is for the plain 10mg vial.

Ipamorelin dosage calculator

Pick the water and the dose, and the calculator gives the units to draw on a U-100 insulin syringe. It opens on a 10mg vial with 3mL and a 200mcg dose: 6 units.

Ipamorelin dosage chart

100 to 200mcg per injection, taken once, twice or three times a day. From a 10mg vial mixed with 3mL of bac water, every 100mcg fills 3 units of a U-100 insulin syringe, so the whole working range sits between 3 and 6 units.

Most protocols open with the single bedtime injection at 100mcg for the first week, move to 200mcg, and only then add a morning injection. A third injection, after training, is the upper end. The largest single injection in common use is 300mcg, 9 units; protocols that want more growth hormone add an injection rather than enlarge one, because every injection is its own pulse.

The amounts are flat: the same draw for a small or a large body, for women and men. They also sit far below what people have been given in trials. In the largest, 117 surgical patients received ipamorelin twice daily for as long as a week at about 12 times the top of this chart per dose, and side effects turned up slightly less often than in the placebo group.

How much bac water for ipamorelin 10mg

3mL. Every 100mcg is then 3 units on the syringe: 200mcg is 6 units and 300mcg is 9.

Wipe both stoppers with alcohol, let the water trickle along the glass rather than onto the powder, then roll the vial gently between the fingers; shaking foams it. Ipamorelin is small and dissolves fast: the white cake clears within a minute or two into a solution as clear and colorless as the water that went in. Write the date on the vial and keep it in the fridge at 2–8°C (36–46°F); a mixed vial is used within 28 days. The same steps for every peptide vial are in how to reconstitute peptides.

Simms Research’s bacteriostatic water, Research Water, is $20 for 10mL, enough for three 10mg vials at 3mL each. Why it has to be bacteriostatic rather than plain sterile water is covered in bac water for peptides. A 5mg vial from another supplier takes 1.5mL for the same strength, and every unit count in this guide then holds; for any other vial or water amount, the peptide calculator gives the units.

Ipamorelin dosage in units and mL

200mcg is 6 units, or 0.06mL, from a 10mg vial mixed with 3mL. A U-100 insulin syringe holds 100 units to the mL, and at this strength every 100mcg is 3 units:

Micrograms carry over from one guide to another; units don’t, because they depend on the water. Any dose found elsewhere goes through the table above or the calculator before it goes on the syringe.

Draws this small call for a 30-unit (0.3mL) syringe, the size with a line for every unit. The common 1mL barrel has a line every two units, so 3 or 9 units falls between its marks.

Ipamorelin dosage per day and timing

200mcg a day is the most common total: one injection of 200mcg at bedtime, on an empty stomach. Daily totals run from 100mcg, the single starting injection, to 600mcg, three injections of 200mcg.

Bedtime comes first because of how growth hormone is released. The body’s largest pulse of the day arrives soon after falling asleep, in the first stretch of deep sleep, and an injection in the last half hour before bed adds to it. Ipamorelin’s own pulse is short. Given to healthy men at five dose levels, it set off one release of growth hormone that topped out around 40 minutes and then dropped away, and the peptide itself had a half-life of two hours (Gobburu, Pharmaceutical Research, 1999).

Food is the other half of the timing. In healthy volunteers, a glucose drink cut the growth hormone response to ghrelin, the hormone ipamorelin copies, by about 60%, and a fat infusion cut it by about 40% (Broglio, Clinical Endocrinology, 2002). Protocols therefore inject two hours or more after the last meal and hold the next one for about 30 minutes, which is easiest at bedtime.

A second injection goes in on waking, before breakfast. A third, in three-a-day protocols, goes in after training and before the post-workout meal or shake, since exercise sets off a growth hormone rise of its own, which the injection builds on. Each one follows the same food rule.

Ipamorelin dosage per week and cycle length

1.4mg a week at the standard 200mcg every night, and 0.7 to 4.2mg a week across the protocols in the chart. A run is 8 to 12 weeks, often on a five-on, two-off week, followed by about four weeks off before the next one.

Once water goes in, the vial has 28 days in the fridge, counted from mixing day. Up to about 350mcg a day, that limit ends the vial before the powder runs out, so a 12-week run takes three vials, one for each four weeks. Above that, the dose empties the vial first: 25 days at 400mcg a day, 17 at 600mcg.

Ipamorelin alone vs with CJC-1295

Ipamorelin works alone. Its developers at Novo Nordisk called it the first selective growth hormone secretagogue: in their 1998 tests it matched GHRP-6 for growth hormone release, yet cortisol and ACTH stayed flat at over 200-fold the effective dose (Raun, European Journal of Endocrinology, 1998). That clean profile is why so many protocols run it by itself: one bedtime injection from one vial.

CJC-1295 makes each pulse larger. It copies GHRH, the brain’s growth hormone-releasing signal, while ipamorelin copies ghrelin; they reach the same pituitary cells through separate receptors, and together they release more than either alone. Simms Research’s blend puts 5mg of CJC-1295 without DAC and 5mg of ipamorelin in one 10mg vial, so it is not dosed like the plain vial: with the same 3mL in each, 6 units of plain ipamorelin is 200mcg, while 6 units of the blend is 100mcg of each peptide. The blend’s water, units and schedule are in the CJC-1295 Ipamorelin dosage guide, and the shops that stock it are compared in where to buy CJC-1295.

Two other GHRH-type partners use the same bedtime slot with ipamorelin unchanged at 100 to 200mcg. Tesamorelin keeps its own daily 1 to 2mg, drawn from its own vial; the units are in the tesamorelin dosage guide. Sermorelin, GHRH cut down to its active 29-amino-acid fragment with nothing else changed, is usually run at 200 to 300mcg at bedtime. Simms Research stocks tesamorelin in 10mg and 20mg vials and sermorelin in 10mg.

What the ipamorelin batch report shows

A little more ipamorelin than the label. The current batch, 2026-IN390, averaged 10.32mg across three vials at 99.767% purity, tested in July 2026 by an independent ISO-certified lab. The batch before it came in at 10.29mg.

For the syringe, the extra 3% is small. A 6-unit draw from an IN390 vial mixed with 3mL carries about 206mcg instead of 200mcg, well inside the width of a single unit line, so the unit counts in this guide stand. Three vials measured within a third of a milligram of one another, which is what keeps one vial dosing like the next.

Both certificates open in full from the ipamorelin lab results page, and the guide to how to read a peptide certificate of analysis explains each line.

Frequently asked questions

How much is 10 units of ipamorelin?

About 330mcg from a 10mg vial mixed with 3mL, a little over the 300mcg (9 units) that protocols use as their largest single dose. The standard 200mcg injection is 6 units.

How many units of ipamorelin should I take?

6 units for the standard 200mcg dose, from a 10mg vial mixed with 3mL. Starting protocols draw 3 units, 100mcg. The unit count changes with the water; the microgram dose doesn’t.

What is a good starting dose of ipamorelin?

100mcg once a day at bedtime, 3 units from a 3mL mix, for the first week, then 200mcg.

Is ipamorelin taken daily or weekly?

Daily. Each injection gives one pulse and the peptide is gone within hours, so a weekly injection would mean one pulse a week (Gobburu, Pharmaceutical Research, 1999). Five days on and two off is the lightest common schedule.

What is the ipamorelin dosage for women?

The same 100 to 200mcg per injection, on the same schedules. Ipamorelin protocols don’t change with sex or body weight.

How much ipamorelin is too much?

Protocols top out at 300mcg per injection, 9 units of a 3mL mix, and at three injections a day.

Does ipamorelin make you hungry?

Some researchers notice mild hunger in the hour after a dose. Ipamorelin acts on the ghrelin receptor, the one behind the body’s hunger signal.

Does ipamorelin need to be refrigerated?

The sealed powder tolerates room temperature for weeks, which is why it ships without ice, and keeps longest refrigerated at 2–8°C (36–46°F) or at −20°C. Once mixed, it lives in the fridge and is used within 28 days. More in Do Peptides Need to Be Refrigerated?

Is ipamorelin dosed in IU?

No, in micrograms. IU is the unit for growth hormone itself, which ipamorelin makes the body release rather than supplying.

Is ipamorelin approved?

No. Simms Research sells ipamorelin for laboratory research use only.
