Ready-to-use starter kit
CJC-1295 with DAC is a synthetic peptide designed as a long-acting analog of the growth hormone-releasing hormone (GHRH). Through the added Drug Affinity Complex (DAC), the molecule binds to the albumin protein, extending its half-life to 6-8 days and providing continuous receptor stimulation. Scientists study this compound in in vitro and animal models to observe the effects of prolonged, non-pulsatile growth hormone release. This product is intended strictly for research purposes and is not an approved medication for human use.

CJC-1295 with DAC (Drug Affinity Complex) is a modified version of growth hormone releasing hormone (GHRH) engineered for extended duration. The addition of DAC technology extends the half-life to 6-8 days, providing continuous growth hormone elevation rather than pulsatile release. This long-acting formulation offers convenience but differs significantly from natural GH secretion patterns.
6-8 day half-life - weekly dosing DAC-mediated albumin conjugation Continuous GH bleed - not pulsatile Appropriate for chronic IGF-1 elevation research
DAC technology binds to albumin, extending half-life to 6-8 days and providing continuous GHRH receptor stimulation
Provides continuous growth hormone release for 6-8 days per injection
Significantly elevates IGF-1 levels for extended periods
Weekly dosing schedule ideal for those seeking simple administration

[Step by step]
6 steps from a sealed vial to the injection. Plain language.
Peptide vial (10 mg), bacteriostatic water vial, 1 larger syringe (3-5 ml) for drawing water and 1 insulin (1 ml) for doses. Alcohol swabs for sanitizing the caps.
Wash your hands before starting.
Wipe the rubber cap of the water vial with an alcohol swab. Insert the needle, invert the vial and draw exactly 2 ml. Get the exact volume from the calculator.
Larger syringe = smaller error in volume.
Wipe the peptide vial cap. Tilt the vial 45° and release the water SLOWLY down the inner wall. Peptides are fragile — a direct stream onto the powder denatures them.
SLOWLY · DOWN THE WALL · NOT ONTO THE POWDER.
Hold the vial between both palms and swirl slowly. DO NOT shake or flip sharply — peptides break down under mechanical stress.
DON'T SHAKE. Like tea — not like a cocktail.
The powder should fully dissolve. The solution is clear, no visible particles. If cloudy or with sediment — discard (wrong water or bad batch).
Clear = OK. Cloudy = discard.
With the insulin syringe draw the exact marks from the calculator. Swab the skin (abdomen 5 cm around the navel, thigh, or buttock), pinch a fold, insert at 45-90° and inject slowly.
Rotate sites every injection to avoid lipohypertrophy.
Schedule
Any time of day - timing less critical due to long half-life
Clean both vial tops with alcohol and let dry completely
For 2mg vial: Add 1mL bacteriostatic water (creates 2mg/mL concentration)
For 5mg vial: Add 2.5mL bacteriostatic water (creates 2mg/mL concentration)
Inject water very slowly to prevent foaming - DAC peptides foam easily
Let sit for 5 minutes before gently rolling to mix
Solution may appear slightly cloudy initially but should clear

Comparative Pharmacokinetics: DAC vs Non-DAC Variants (2015)
Human | Crossover design | 30 days each arm
DAC version showed 120-hour half-life versus 30-minute half-life of non-DAC, but non-DAC preserved more physiological GH patterns.
Long-term Effects on GH/IGF-1 Axis (2012)
Animal model | 6 months | Weekly dosing
Chronic administration led to sustained IGF-1 elevation but some evidence of reduced GH pulse amplitude, suggesting partial desensitization.
Dose-Response Relationship of CJC-1295 DAC (2008)
Human | Multiple doses | 90 days | 48 subjects
Established optimal dosing at 1-2mg weekly, showing dose-dependent IGF-1 increases but also higher side effect incidence at doses above 2mg.
Prolonged Growth Hormone Elevation with CJC-1295 DAC (2006)
Human | 30-60mcg/kg | Single injection | 12 subjects
Demonstrated sustained GH and IGF-1 elevation for 6-10 days following a single injection, with peak levels 2-4x baseline maintained throughout.
