CJC-1295 vs Hexarelin: Two Receptors, Two Evidence Records, and Which One Fits

Every figure is an all-in monthly price covering the medication, physician review, refill management and shipping. There is no separate membership fee, and Pepti is cash-pay and does not bill insurance. Current pricing always lives on each product page.

The real difference is selectivity and fade, not strength

People often ask which is "stronger." Hexarelin produced a larger single-dose growth hormone response than GHRH in the 1990s human studies, but a bigger pulse is not the whole story. Hexarelin's pulse comes with a rise in cortisol and prolactin, and its response falls with continuous use. CJC-1295 is a different signal at a different receptor, and the prescribed form is short-acting and usually paired with ipamorelin precisely so that each dose gives one clean pulse. No study has compared CJC-1295 with hexarelin directly.

The desensitisation question

In a 1998 Journal of Clinical Endocrinology and Metabolism study, healthy elderly adults took twice-daily subcutaneous hexarelin for sixteen weeks. The growth hormone response to a test dose fell by about a third by week one and by nearly half by week sixteen, and returned to baseline four weeks after stopping. Shorter intermittent schedules in older adults did not show desensitisation. That is the rationale for Pepti's five-nights-on, two-off hexarelin schedule. Desensitisation is not a described feature of CJC-1295 in the same way, which is one reason a GHRH-plus-ipamorelin pairing is the more usual choice for a course that runs uninterrupted.

A committee vote is a recommendation, not a ban, and it evaluated CJC-1295 for growth hormone deficiency against the approved drugs that already exist for it. Ipamorelin, CJC-1295's partner, had a similar committee vote against it in October 2024 with no final determination. Hexarelin has simply never been taken up by the FDA either way. Both remain legal to prescribe and dispense as compounded medications. Compounded medications are not FDA approved, and neither CJC-1295 nor hexarelin is an FDA-approved drug. Are peptides FDA approved explains the difference.

Both are injected under the skin (subcutaneously) into the abdomen or thigh, rotating sites. The empty-stomach instruction on CJC-1295 / Ipamorelin matters because glucose and fatty acids after a meal blunt the growth hormone pulse; many prescribers direct it at bedtime. Hexarelin's bedtime timing lands its pulse on top of the natural nocturnal release, and food intake was reported in 2000 to modulate its response. You do not need to calculate anything: your directions are printed on the vial, and your physician sets them after reviewing your intake. Refills run every 28 days, one vial per fill. Vials are multi-dose solutions shipped ready to use, refrigerated with ice packs, with sterile syringes and alcohol prep pads. CJC-1295 / Ipamorelin also comes as a 3 mL pre-filled Pen cartridge containing 1.5 mg CJC-1295 and 6 mg ipamorelin, with Pen directions printed separately.

Bloodwork is not required for any Pepti treatment. If your physician wants labs for your care, they'll ask through your account.

CJC-1295 / Ipamorelin. In the 2006 CJC-1295 trials, injection-site reactions and headache were the main complaints. Reported clinically: injection-site redness or soreness, a brief flush after injecting, headache, and, with the growth hormone rise, water retention or tingling in the hands, which usually settle. Some people notice hunger after a dose.

Hexarelin. Single doses were consistently reported as well tolerated in the 1990s studies. Reported clinically: warmth or flushing after the injection, hunger, a transient headache, light-headedness, and injection-site redness or soreness. Each dose also raises cortisol and prolactin for an hour or two, and a single dose produced a short-lived rise in the heart's contractility in every human study that looked, so a cardiac diagnosis belongs on the intake.

For both, growth hormone opposes insulin, so blood glucose can drift up, and anything that raises growth hormone and IGF-1 carries the class concerns of glucose intolerance, fluid retention and a theoretical concern about existing tumours. There is no established interaction list for either. Stop and contact your physician for any reaction that is severe or spreading. Swelling of the face, lips or throat, a widespread rash or difficulty breathing needs emergency care first: call 911, then tell your care team. More in is CJC-1295 / Ipamorelin safe.

Both reliably raise growth hormone in people; that much is established. Beyond that, the evidence is thin for both. CJC-1295's human data is pharmacokinetic and for the DAC form, not the form prescribed today. Hexarelin's human record is deep but old, almost all single-dose pharmacology, and the one sustained subcutaneous course in adults found no change in body composition. Neither has a trial showing better sleep, recovery or body composition, and no study has compared them. Physicians prescribe both on pharmacology plus clinical experience. The honest framing is "known to raise growth hormone in humans; benefits beyond that are inferred," not "shown to work." The wider class is compared in CJC-1295 vs sermorelin and peptides vs HGH.

Neither can be bought legitimately without a prescription. Sites selling them "for research use only" are not accountable for what is in the vial: identity, purity, sterility and concentration are untested. The prescription route:

1. Complete a free online intake covering your history, medications and what you want help with.
2. A physician licensed in your state reviews it, usually within 24 hours.
3. If it is appropriate, a PCAB-accredited, FDA-registered US 503A compounding pharmacy prepares it to that prescription. Lot test results are published at /quality/lab-results.
4. It ships refrigerated with your directions printed on the vial.
5. Your physician stays reachable for questions and dose changes.
