At a Glance
CJC-1295 No DAC + Ipamorelin is a pre-blended lyophilised peptide combining 5 mg Modified GRF 1-29 (CJC-1295 No DAC) with 5 mg ipamorelin in a single 10 mg vial. The two act on distinct receptors in the same GH axis: GHRH-R via cAMP and GHS-R1a via calcium. The result is synergistic GH release that exceeds either peptide alone.[1]
- Reconstitute: Add 3.0 mL bacteriostatic water → 3.33 mg/mL total (1.67 mg/mL per component).
- Standard dose: Titrate from 100 mcg each (200 mcg total) up to a target of 250–300 mcg each (500–600 mcg total) subcutaneous, once daily. Pre-sleep injection is standard.
- Easy measuring: At 3.33 mg/mL total on a U-100 syringe, 1 unit = 0.01 mL = 33.3 mcg total (16.7 mcg per peptide). A 100 mcg-each dose (200 mcg total) = 6 units / 0.06 mL.
- Storage: Lyophilised: refrigerate at 2–8 °C (freeze at −20 °C for long-term); reconstituted: refrigerate at 2–8 °C; use within 4 weeks.
Overview
- Composition: 5 mg CJC-1295 No DAC (Modified GRF 1-29) + 5 mg ipamorelin per 10 mg lyophilised vial.
- Goal: Synergistic stimulation of endogenous pulsatile GH release via dual receptor engagement on pituitary somatotrophs.[1]
- Schedule: Once-daily subcutaneous injection, on an empty stomach. Pre-sleep is the most common timing.
- Dose range: 100–300 mcg per peptide (200–600 mcg total) per injection, titrated upward over the cycle.
- Reconstitution: 3.0 mL BAC water per 10 mg vial → 3.33 mg/mL total.
- Injection site: Abdomen, thigh, or upper arm; rotate daily.
What You'll Need
Plan based on a representative 12-week titrated cycle, once daily (84 injections, ~33.6 mg total across the escalating schedule).
- CJC-1295 No DAC + Ipamorelin Vials (10 mg each): ~33.6 mg needed ÷ 10 mg per vial → 4 vials (40 mg covers the cycle with buffer).
- Insulin Syringes (U-100, 0.3 mL / 30-unit preferred): 84 injections → 84 syringes.
- Bacteriostatic Water (10 mL bottles): 3.0 mL per vial × 4 vials = 12 mL → 2 × 10 mL bottles.
- Alcohol Swabs: 2 per injection → 168 swabs per 12-week cycle.
How to Reconstitute
- Allow the refrigerated lyophilised vial to reach room temperature (10–15 minutes).
- Draw 3.0 mL bacteriostatic water with a sterile syringe.
- Inject slowly down the inner vial wall; do not spray directly onto the powder.
- Gently swirl or roll until fully dissolved. Do not shake. Solution should be clear and colourless.
- Label with reconstitution date and both component names; refrigerate at 2–8 °C. Use within 4 weeks.
Dosing Schedule
| Phase | Dose (each) | Total Dose | Units (U-100) | Volume | Frequency |
|---|---|---|---|---|---|
| Weeks 1–2 | 100 mcg | 200 mcg | 6 units | 0.06 mL | Once daily |
| Weeks 3–4 | 150 mcg | 300 mcg | 9 units | 0.09 mL | Once daily |
| Weeks 5–6 | 200 mcg | 400 mcg | 12 units | 0.12 mL | Once daily |
| Weeks 7–12 | 250–300 mcg | 500–600 mcg | 15–18 units | 0.15–0.18 mL | Once daily |
Start at 100 mcg per peptide and increase by ~50 mcg each every 1–2 weeks as tolerated, targeting 250–300 mcg per peptide by weeks 7–12. Administer on an empty stomach; insulin from a recent meal suppresses GH secretion. Pre-sleep timing captures the nocturnal GH window. At the 600 mcg total peak (300 mcg each, 18 units once daily) one 10 mg vial provides ~16 days; at the 200 mcg total starting dose, 50 days.[1]
Protocol Details
- Weeks 1–2 (start): 100 mcg each (200 mcg total, 6 units / 0.06 mL) once daily in the evening.
- Weeks 3–4: 150 mcg each (300 mcg total, 9 units / 0.09 mL) once daily.[1]
- Weeks 5–6: 200 mcg each (400 mcg total, 12 units / 0.12 mL) once daily.
- Weeks 7–12 (target): 250–300 mcg each (500–600 mcg total, 15–18 units / 0.15–0.18 mL) once daily.
- Cycle length: 8–12 weeks on, with optional extension to 16 weeks. A 4-week off period afterward is a pep-dose recommendation (not from the source protocol) to support receptor sensitivity recovery.
- Injection site: Abdomen, thigh, or upper arm; rotate daily to minimise site reactions.
Storage
- Lyophilised: Refrigerate at 2–8 °C (35–46 °F); freeze at −20 °C for storage beyond 3 months. Protect from light.
- Reconstituted: Refrigerate at 2–8 °C. Avoid freeze-thaw cycles. Use within 4 weeks.
- Appearance: Clear, colourless solution. Discard if cloudy, coloured, or particulate.
How CJC-1295 No DAC + Ipamorelin Works
The two peptides act at different receptors on the same pituitary cell.
CJC-1295 No DAC (Modified GRF 1-29) is a 29-amino acid analogue of endogenous GHRH with four substitutions (D-Ala², Gln⁸, Ala¹⁵, Leu²⁷) that confer resistance to DPP-IV cleavage.[2] It binds the GHRH receptor (GHRH-R) on pituitary somatotrophs, activating Gs/adenylyl cyclase/cAMP/PKA to drive GH synthesis and release. Half-life: ~30 minutes, a clean pulse aligned with natural pulsatility, without the prolonged albumin-binding extension of the DAC form. CAS 863288-34-0. MW 3367.95.
Ipamorelin binds GHS-R1a (the ghrelin receptor) on the same cells, coupling through Gαq → PLC → IP₃ → calcium release to trigger a separate secretory cascade.[3] CAS 170851-70-4. MW 711.85.
When both act simultaneously, the cAMP signal from GHRH-R and the calcium signal from GHS-R1a converge as mutually reinforcing secretory inputs. The result is a GH pulse larger than either peptide produces alone.[1]
Good to Know
- Both peptides have a half-life of ~30 minutes. Timing relative to sleep and fasting matters more than with longer-acting analogues.
- CJC-1295 No DAC (Modified GRF 1-29) is a distinct compound from CJC-1295 with DAC. The DAC cysteine modification binds albumin and extends half-life to 6–8 days, a fundamentally different pharmacokinetic profile. This vial contains the No-DAC form only.
- Administer on an empty stomach; insulin suppresses the GH pulse.
- WADA status: Both peptides are S2-class non-approved peptides. Athletes under anti-doping programmes must not use this blend.

Tips for Best Results
- Inject on an empty stomach, at least 1–2 hours after the last meal. Pre-sleep is the primary timing in most research protocols.
- Injecting once daily on an empty stomach, fasted before bed or on waking, keeps the GH pulse aligned with natural pulsatility.
- Pair with adequate protein (1.2–1.6 g/kg) and consistent sleep (7–9 hours); GH/IGF-1 elevation works in concert with recovery.
- Avoid eating for 30–60 minutes post-injection.
- Track injection sites and rotate; note any local reactions on the first few injections.
Injection Tips
- Clean the vial stopper and injection site with separate alcohol swabs; allow both to air-dry fully before proceeding.
- Using a 29–31 gauge insulin syringe (5/16″ to 1/2″ needle), draw the calculated dose precisely.
- Pinch a fold of skin and insert the needle at 45° into subcutaneous fat (90° is acceptable with a short needle into a well-pinched fold).
- Inject slowly over 2–3 seconds; do not aspirate. Withdraw the needle, apply gentle pressure, and do not rub the site.
- Rotate injection sites (abdomen, thighs, upper arms) and dispose of each syringe in a sharps container immediately after use.[4]
