CJC-1295 (no DAC)
Also known as Mod GRF 1-29, CJC-1295 without DAC
Short-acting growth hormone releasing hormone analogue.
Medical status: Not approved as a medicine.
Also commonly used for (off-label)
- Boosting natural GH pulses
- Recovery, sleep and body composition
Off-label and research uses are what people report, not approved indications. Talk to a clinician before using any of them.
How it's taken (route)
a small shot into the fat just under the skin (belly, thigh, or love handle)

Dose on a U-100 syringe (100–500 mcg)
| Vial | BAC water | Draw |
|---|---|---|
| 2 mg | 1.5 mL | 7.5–38 units |
| 2 mg | 2 mL | 10–50 units |
| 5 mg | 2.5 mL | 5.0–25 units |
| 5 mg | 3 mL | 6.0–30 units |
| 10 mg | 2.5 mL | 2.5–13 units |
| 10 mg | 3 mL | 3.0–15 units |
On a U-100 syringe, 100 units = 1 mL, and the syringe holds 100 units total. Most people keep a single subcutaneous injection under about 50 units — bigger volumes are usually mixed stronger (less water) or split into two shots. Only mixes that fit in one syringe are shown. Always double-check with the reconstitution calculator.
What it does
Also called Mod GRF 1-29. It nudges the pituitary gland to release your own growth hormone in a natural burst, rather than adding synthetic hormone from outside. What people look into it for: • Better deep sleep and feeling more rested • Faster recovery between training sessions • Gradual improvements in lean muscle and body composition • Skin, hair and connective-tissue quality Because it clears quickly, it is usually dosed before bed and often paired with a ghrelin-type peptide such as ipamorelin for a stronger pulse.
Mechanism
GHRH analogue binding pituitary GHRH receptors to stimulate endogenous GH secretion.
Storage — lyophilisedwhat's this?
Refrigerate 2-8C, protect from light.
Storage — reconstitutedwhat's this?
Refrigerate 2-8C, use within ~28 days.
Reconstitution noteswhat's this?
Common mix: 10 mg vial + 2.5 ml bacteriostatic water = 40 mcg per unit (100 mcg ≈ 3 units, 300 mcg ≈ 8 units). Best taken fasted, 2–3 hours after food.
Stacks well with
- IpamorelinThe standard pairing: GHRH plus a selective secretagogue for a clean GH pulse.
- TB-500Added during injury recovery blocks.
Popular combinations reported in the community and research literature — not a recommendation. Adding peptides multiplies side-effect risk; check with a clinician.
Commonly reported side effects
- Injection-site redness
- Water retention
- Head rush
- Tingling hands
Contraindications noted
- Active malignancy
- Pregnancy or breastfeeding
- Uncontrolled diabetes
Research notes
Best characterised when dosed on an empty stomach; frequently paired with Ipamorelin in the literature.
