Overview

What is CJC-1295 with DAC?

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. Banned by WADA

Key Benefits

Convenient weekly dosing, sustained GH/IGF-1 elevation, significant body composition changes.

Mechanism of Action

DAC technology binds to albumin, extending half-life to 6-8 days and providing continuous GHRH receptor stimulation.

Research Indications

Sustained GH Elevation

Provides continuous growth hormone release for 6-8 days per injection.

IGF-1 Optimization

Significantly elevates IGF-1 levels for extended periods.

Convenience Protocol

Weekly dosing schedule ideal for simple administration.

Research Protocols

Disclaimer: Cycling (8-12 weeks on, 4-8 weeks off) is commonly discussed to help maintain pituitary sensitivity from continuous GHRH stimulation. Unlike the non-DAC version, a loading phase is generally not reported due to the long half-life.

Timing: Due to long half-life, injection timing is flexible. Many prefer morning injections to monitor for side effects during the day.

Peptide Interactions

How to Reconstitute

Important: Always use bacteriostatic water (BAC). Sterile technique is essential.

1

Clean both vial tops with alcohol and let dry completely

2

For 2mg vial: Add 1mL bacteriostatic water (creates 2mg/mL concentration)

3

For 5mg vial: Add 2.5mL bacteriostatic water (creates 2mg/mL concentration)

4

Inject water very slowly to prevent foaming - DAC peptides foam easily

5

Let sit for 5 minutes before gently rolling to mix

6

Solution may appear slightly cloudy initially but should clear

7

Label with date and concentration immediately

Quality Indicators

High Purity Requirement

DAC peptides require >98% purity - impurities cause more side effects.

Proper DAC Labeling

Legitimate products clearly state 'with DAC' to distinguish from regular CJC-1295.

More Expensive than Non-DAC

DAC version costs 2-3x more due to complex manufacturing.

Foaming During Mixing

Normal for DAC peptides to foam - wait for foam to settle.

Extremely Cheap Pricing

If priced similar to non-DAC version, likely mislabeled or fake.

Clear Solution Immediately

Should be slightly cloudy initially - immediate clarity may indicate non-DAC.

What to Expect

  • Week 1: Possible water retention, improved sleep, increased appetite
  • Week 2-3: Noticeable recovery improvements, some report joint discomfort
  • Week 4-6: Visible body composition changes, increased vascularity
  • Week 6-8: Continued improvements but watch for desensitization signs
  • Post-cycle: Maintain most gains, IGF-1 returns to baseline in 2-3 weeks

Side Effects & Safety

Side Effects

  • Higher side effect incidence than pulsatile protocols
  • Common: Water retention, joint pain, carpal tunnel symptoms
  • Monitor for signs of excessive GH: jaw growth, hand/feet enlargement
  • Not suitable for those with diabetes or cancer history
  • May worsen sleep apnea in predisposed individuals
  • Regular IGF-1 monitoring recommended for long-term use

When to Stop

  • Signs of excessive GH (jaw/hand growth)
  • Severe water retention
  • Significant joint pain
  • Sleep apnea worsening
  • As directed by healthcare provider

3 Studies

DAC vs Non-DAC Pharmacokinetics (2015)

Human | Crossover design | 30 days each arm | 120-hour vs 30-minute half-life

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 | Sustained IGF-1 elevation

Chronic administration led to sustained IGF-1 elevation but some evidence of reduced GH pulse amplitude, suggesting partial desensitization.

Dose-Response Relationship (2008)

Human | Multiple doses | 90 days | 48 subjects | Optimal 1-2mg weekly dosing

Established optimal dosing at 1-2mg weekly, showing dose-dependent IGF-1 increases but higher side effects above 2mg.

Quick Start Guide

Typical Dose
1-2mg (0.5-1mL if mixed at 2mg/mL)
How Often
Once weekly - same day each week
Where to Inject
Subcutaneous: Abdomen (preferred)
Timing
Any time of day - timing less critical due to long half-life
Effects Timeline
IGF-1 elevation within 24-48 hours, peak benefits weeks 2-6, body composition changes weeks 4-8
Storage
Refrigerate immediately, more stable than non-DAC - use within 60 days
Cycle Length
8-12 weeks maximum
Break Between
4-6 weeks mandatory to prevent desensitization
