CJC-1295 DAC Dosage Calculator & Chart

1Set Up Your Mix

2.5 mg/mL · 2500 mcg/mL

1. Pick your peptide

2. How much peptide is in the vial? It's printed on the label — usually something like 5 mg

3. How much water are you adding? More water makes each dose easier to measure

4. How much do you want per dose?

Your Answer — CJC-1295 DAC

5 mg in 2 mL

0.4That's This Many mL

5Doses In The Vial

5 mg ÷ 2 mL = 2.5 mg/mL → 1 mg ÷ 2.5 mg/mL = 0.4 mL → × 100 = 40 units

Looks good. Draw to 40 units on a 1 mL syringe. That is an easy amount to measure, and this vial gives you 5 doses.

When to dose

Time of dayBefore bed, or first thing in the morning — not during the day.

FoodFasted. Nothing to eat for about 2 hours before, and wait 20–30 minutes after.

Food, and carbohydrate in particular, raises insulin and blunts the growth-hormone pulse these compounds are meant to trigger. The two windows where you are naturally fasted and GH release is highest are early sleep and first thing on waking, which is why those are the only two sensible times.

Where this plan came from

Built from this peptide's dose range

Where this came from: Built from the doses listed for this peptide below — start at the lowest and step up, using the studies cited on this page. Nobody publishes a week-by-week plan for this peptide, so we built one: the doses are the researched ones shown below, and we simply put them in order from lowest to highest. Treat it as a starting point, not an official schedule.

About CJC-1295 DAC

GH Secretagogue

Also known as

CJC-1295 with drug affinity complex

Class

GH Secretagogue

Route

Subcutaneous

Half-life

~6–8 days

Evidence tier

Clinical

GHRH analogue conjugated to bind serum albumin, extending half-life from minutes to days. This produces sustained GH/IGF-1 elevation rather than pulses — a meaningfully different physiological profile from the no-DAC version.

Common Questions — CJC-1295 DAC

How much bacteriostatic water do I add to a 5 mg vial of CJC-1295 DAC?

Adding 2 mL of bacteriostatic water to a 5 mg vial gives 2.5 mg/mL. That is the mix every number on this page is worked out from — change the water figure in the calculator and all the draw amounts update.

What dose of CJC-1295 DAC is used in research?

Published and reported figures for CJC-1295 DAC run from 1 mg to 2 mg, typically once weekly. This site lists each figure with the source it came from rather than giving a single recommended number.

How many units on the syringe is a 1 mg dose of CJC-1295 DAC?

At 2.5 mg/mL, a 1 mg dose is 40 units on a 1 mL U-100 insulin syringe. One vial at that mix gives about 5 doses.

How strong is the evidence behind these CJC-1295 DAC doses?

CJC-1295 DAC is graded clinical. Human trial or approved-label dosing has been published for this compound. We grade every compound on this site so you can weigh the numbers accordingly — the full method is on our editorial policy page.
