CJC-1295 No DAC Tracker
CJC-1295 No DAC is a short-acting GHRH analogue, the same base molecule as the DAC version without the albumin-binding complex. This page covers its half-life, what that timescale means for keeping a usable record, and how it changes the shape of a log — not what to take or how much.
What CJC-1295 No DAC's timing means for tracking
This is the shortest half-life on the whole site: about 30 minutes. It is essentially gone within two and a half hours.
The comparison that makes this page worth reading is with CJC-1295 with DAC, which sits at roughly 192 hours. Same base analogue, same name in most conversations — and a difference of roughly 384 times. People routinely say "CJC-1295" meaning either one, which is a genuine source of confusion when reading anyone else's log or protocol.
Practically, a 30-minute half-life means a record built on dates alone is close to useless. The entire event lives inside a couple of hours. If your log captures the time, it describes something real; if it captures only the day, it describes almost nothing.
What to capture in the log
- Clock time is essential, not optional, at this timescale.
- Record entries individually — daily aggregates erase the only signal there is.
- Be explicit in your own notes about which CJC-1295 you mean. The two versions are not interchangeable.
Worked reconstitution example
Purely as arithmetic, using round numbers rather than a recommendation. If a 5 mg vial were mixed with 2 mL of bacteriostatic water, the concentration would be 2.5 mg/mL. Measuring 100 mcg from that would come to:
4 units on a U-100 syringe
5 mg ÷ 2 mL = 2.5 mg/mL → 100 mcg = 0.04 mL = 4 units
Change either the vial size or the water and this number changes completely. Run your own figures in the reconstitution calculator.
Frequently asked questions
What is the half-life of CJC-1295 without DAC?
About 30 minutes, with an estimated activity window near 4 hours. It is the shortest half-life in PepTrack's catalogue.
Is Mod GRF 1-29 the same as CJC-1295 no DAC?
They are commonly used as the same name for the same short-acting GHRH analogue, and PepTrack lists Mod GRF 1-29 as an alias.
Why do the DAC and no-DAC versions differ so much?
The Drug Affinity Complex binds the peptide to serum albumin and slows clearance enormously — roughly 192 hours against roughly 0.5 hours.
How many units is 100 mcg?
With a 5 mg vial in 2 mL the concentration is 2.5 mg/mL, or 25 mcg per unit, so 100 mcg is 4 units. That is a very small draw; mixing with more water spreads it across a more readable part of the syringe.
