two-peptide blend (GHRH analog + GH secretagogue) · studied for growth hormone release, sleep, recovery and body composition (user reports; no trial of the pair)

CJC-1295 + Ipamorelin blend dosage

This is the most common growth hormone stack sold as one vial, usually 5 mg of CJC-1295 without DAC and 5 mg of ipamorelin in a 10 mg vial. The two work on different receptors and are dosed together: 100 to 200 mcg of each per injection, one to three times a day, fasted, bedtime first. Cycles run 8 to 16 weeks. No trial has tested the pair, and neither peptide is approved.

CJC-1295 + Ipamorelin blend dose to units chart

10 mg vial + 2.5 mL bacteriostatic water = 4 mg/mL (40 mcg per unit on a U-100 insulin syringe). 10 mg blend (5 mg CJC-1295 no DAC + 5 mg ipamorelin) + 2.5 mL = 4 mg/mL total, so 400 mcg total = 0.1 mL = 10 units, delivering 200 mcg of each. 200 mcg total = 5 units.

Dose	mL	Units (U-100)	Doses per vial

Before you start. Human dosing is not established for either peptide and the pair has never been trialed. Both raise GH and IGF-1, so cancer history and diabetes are reasons for caution, and injecting with food in your stomach mostly wastes the dose. Check the label, because some blends use CJC-1295 with DAC, which changes the schedule to weekly. Not medical advice; start low and talk to a clinician.

CJC-1295 + Ipamorelin blend dosage questions

How do you dose CJC-1295 ipamorelin blend?

Commonly reported: 100 to 200 mcg of each per shot, which is 200 to 400 mcg of total blend, one to three times a day fasted, with bedtime the priority. On a 10 mg (5 + 5) vial in 2.5 mL, 10 units gives 200 mcg of each. Run 8 to 16 weeks.

How many units of CJC ipamorelin should I take?

With a 10 mg blend vial in 2.5 mL, 5 units delivers 100 mcg of each peptide and 10 units delivers 200 mcg of each. With 2 mL of water, 10 units delivers 250 mcg of each. Work from your water volume.

When is the best time to take CJC-1295 ipamorelin?

Right before bed on an empty stomach, 30 minutes or more after your last food, because the natural GH pulse comes in early sleep. A second dose fasted in the morning or after training is the next most common. Food, especially carbs and fat, blunts the response.

How long until CJC-1295 ipamorelin works?

Users commonly report better sleep within the first week and body composition changes after 8 to 12 weeks. There are no trials of the blend, so there is no measured timeline. IGF-1 bloodwork after 4 to 6 weeks is how people check it is doing anything.
