CJC-1295/Ipamorelin Dosage Chart: Units & Timing

CJC-1295/Ipamorelin Dosage Chart

Search for cjc-1295 ipamorelin dosage and the results disagree with each other by a factor of a thousand. One page says 100 micrograms. Another says 2 milligrams. Both numbers are real. They just describe different molecules, and mixing them up is the single most common dosing confusion with this stack. There is a second problem too: most charts assume you bought two separate products and have to work out each peptide on its own. The PeRx product is one combined vial that ships fully reconstituted and ready to use, with CJC-1295 (no-DAC) at 1.2 mg per mL and ipamorelin at 2 mg per mL in the same solution. That changes the math, mostly by deleting it.

Here is the whole conversion. A U-100 insulin syringe holds 100 units per mL, so one unit is 0.01 mL. At 1.2 mg per mL, that 0.01 mL carries 12 mcg of CJC-1295. At 2 mg per mL, the same 0.01 mL carries 20 mcg of ipamorelin. One number on the syringe sets two doses at once, always in the same 12 to 20 ratio, and the ratio cannot drift because both peptides live in one vial.

This page deliberately stays on arithmetic, timing, and cost.

This peptide stack doesn't replace what you've lost with synthetic hormones. It tells your body to start making more of its own again. One peptide carries the GHRH signal that primes release. The other fires the pulse. Together, they're the most popular growth hormone optimization protocol in peptide therapy.Read article covers mechanism and evidence in depth so this one does not have to.

How Many Units Is That on an Insulin Syringe?

Prescriptions and protocols quote this combination three different ways: units, micrograms of ipamorelin, or micrograms of CJC-1295. All three describe the same draw. To go from ipamorelin micrograms to units, divide by 20. To go from CJC-1295 micrograms to units, divide by 12. To go the other way, multiply. Those conversions hold at this vial concentration and no other, which is why a chart from a different pharmacy, or a forum post about someone else’s product, does not transfer.

Now the milligram confusion, because it matters. CJC-1295 exists in two forms that share a name. The version with DAC binds albumin in the blood and keeps working for about a week, which is why studies and clinics that use it quote doses of 1 to 2 mg injected weekly. Teichman and colleagues showed in 2006 that single injections of that long-acting form raised growth hormone concentrations 2 to 10 fold for up to 6 days, with IGF-1 staying elevated for as long as 28 days after repeated dosing. The nightly combo vial contains the other form, CJC-1295 without DAC, which acts for roughly half an hour and is dosed in micrograms every evening. If you plug a 2 mg DAC dose into a no-DAC nightly schedule you are off by more than a factor of ten. When a number you find online is written in whole milligrams, it is not describing this product.

One practical note on hardware. PeRx includes U-100 insulin syringes with every order, so the units in the chart match the barrel in your hand. Volumes under 0.1 mL are easier to read on a 0.3 mL syringe than a 1 mL syringe because the same dose stretches across more hash marks. Draw slowly, hold the syringe at eye level, and read the top of the plunger against the line rather than eyeballing from an angle.

CJC-1295/Ipamorelin

Every conversion on this page comes from one fact: PeRx ships both peptides in a single combined vial at a fixed concentration, prescribed by a licensed provider and compounded at a US-based 503A pharmacy. It arrives fully reconstituted and ready to use, with insulin syringes included.

One draw delivers both peptides together, so there is no juggling two vials or doing two sets of math. $299 for the monthly vial, and your prescription label carries your exact nightly units.

When to Inject CJC-1295/Ipamorelin

The label on this stack could honestly read: evening, empty stomach, then sleep. Adults release growth hormone in pulses, and the biggest pulse of the day is tied to the first stretch of slow-wave sleep. Van Cauter and Plat documented that coupling in their review of GH secretion during sleep: deep sleep arrives, and the dominant nightly pulse arrives with it. Both peptides in this vial act quickly and clear quickly, so an injection 20 to 30 minutes before bed stacks its effect onto that natural pulse instead of firing into the flat part of the afternoon.

The empty stomach rule has equally old roots. Ho and colleagues showed in 1988 that fasting amplifies growth hormone secretion in healthy men, increasing both how often pulses fire and how tall they are, while the glucose and insulin rise after a meal pushes in the opposite direction. Injecting a GH secretagogue on top of a recent dinner asks the pituitary to perform with the brakes partly on. Give it a gap of 1 to 2 hours after your last meal, and skip the late snack afterward. Water is fine.

A reasonable worry about injecting a ghrelin-receptor peptide at night is hunger, since ghrelin is the hormone that makes you want a sandwich. Ipamorelin is the reason that worry does not apply here. Raun and colleagues characterized it in 1998 as the first selective growth hormone secretagogue: it triggered GH release with potency comparable to GHRP-6 but did not raise cortisol or ACTH even at doses 200 times the effective one, and unlike older GHRPs it did not stimulate appetite. A bedtime dose releases growth hormone without leaving you staring into the refrigerator.

Cycling: 5 On, 2 Off

Growth hormone secretagogues are the peptide class where scheduled breaks earn their keep. The pituitary responds to a pulse, and receptors that are stimulated every single night, month after month, can gradually answer more quietly. Two patterns show up in practice for this stack. The weekly version runs 5 nights on and 2 nights off, usually weekdays on and weekends off. The seasonal version runs 3 months on and then 1 full month off. They are not competitors; many prescriptions use both at once, weekdays only inside a 3-month block.

Neither weekly pattern has a head-to-head human trial behind it, so the honest framing is that both are defensible prescriber judgments built on the same physiology. What the field agrees on more firmly is the value of the longer break. Running 3 months and then pausing for 1 month gives the axis a clean reset and gives you a natural checkpoint to repeat an IGF-1 lab before deciding to continue. The peptide cycling guide Read nextPeptide Cycling Chart: When to Pause Each ClassPeptide therapy is rarely meant to run forever. Some peptides need scheduled breaks to keep working. Others can be used continuously. The right cycle depends on the peptide class, your goals, and what is happening at the receptor level.

PeRx ships a ready-to-use vial at one fixed concentration, so the math is different and simpler.

What a Month Costs

CJC-1295/Ipamorelin is $299 per vial at PeRx, one vial per prescription month. That figure includes the licensed provider review, compounding at a US 503A pharmacy, overnight refrigerated shipping, insulin syringes, and alcohol swabs. There is no membership fee, and your card is not charged at checkout; the charge only fires if a provider approves the prescription. A full 3-month cycle is three vials, $897 before any discount.

The per-dose math follows straight from the chart. At 10 units a night, a 5 mL vial physically holds 50 doses, so a month of nightly injections uses a little over half the vial and each injection works out to roughly $10 on a per-vial basis. At 15 units the vial holds about 33 doses. This is also a quiet quality signal worth naming: the chart only works because the concentration is printed, fixed, and pharmacy-verified. Gray-market vials sold for research use carry no such guarantee, and a units chart is worthless when the mg per mL behind it is a guess.

If You Miss a Dose

Skip it. Take your next scheduled dose at the normal time the following evening, and do not draw a double to make up the difference. The logic comes from how the stack works: each injection adds to one night’s growth hormone pulse, and a night that already passed cannot be back-filled. Doubling the volume does not double the release either, because somatostatin feedback caps how much GH the pituitary will let go of in one pulse. Two units of effort, one unit of result, plus a bigger dent in the vial.

A single missed night costs you almost nothing over a 12-week cycle. A missed week is different in degree but not in kind: resume at your prescribed dose on your normal schedule rather than restarting with anything larger. If travel took you away from refrigeration or you are unsure whether a vial was stored properly, message the PeRx care team through your portal before using it. And if you find yourself missing more nights than you hit, that is a routine problem rather than a dosing problem. Moving the injection to a fixed anchor, like right after you brush your teeth, fixes more adherence issues than any schedule change.
