CJC-1295/Ipamorelin combination — what worked for you?

What about CJC-1295 with DAC vs without DAC? I keep seeing conflicting advice. Some sources say the DAC version is better because you only inject 1-2x per week, others say no-DAC (Mod GRF) is superior because the pulses are more physiologic.

This is probably the most debated topic in the GH peptide world. My take:

CJC-1295 with DAC:

• Pro: Convenience — inject 2 mg once or twice per week
• Pro: Sustained IGF-1 elevation (good if that's your goal)
• Con: Creates a "GH bleed" — chronic low-level elevation rather than discrete pulses
• Con: May cause more side effects (water retention, carpal tunnel) due to sustained GH elevation
• Con: Potentially more suppressive of natural GH pulsatility over time

Mod GRF 1-29 (no DAC):

• Pro: Mimics natural GH pulsatility better
• Pro: Synergizes well with Ipamorelin when co-administered
• Pro: Fewer side effects in my experience
• Con: Requires daily injection
• Con: More sensitive to timing (fasting state matters more)

I switched from DAC to no-DAC after about 3 months because I was getting noticeable water retention and occasional hand numbness with the DAC version. The no-DAC version has been much cleaner in terms of side effects while still producing good IGF-1 numbers.

Consensus among experienced users seems to lean toward no-DAC + Ipamorelin as the standard protocol. But reasonable people disagree. 🤷‍♂️

Practical sourcing and reconstitution for this stack:

Both peptides are widely available from US research peptide suppliers. Typical vial sizes:

• Mod GRF 1-29: 2 mg or 5 mg vials
• Ipamorelin: 2 mg or 5 mg vials

You can reconstitute both in the same syringe for a single injection. Reconstitute each vial separately with BAC water, then draw your doses from each vial into one syringe.

Example math for a 5 mg Ipamorelin vial:
Reconstitute with 2.5 mL BAC water = 2000 mcg/mL
200 mcg dose = 0.1 mL (10 units on an insulin syringe)

Example for a 2 mg Mod GRF vial:
Reconstitute with 2 mL BAC water = 1000 mcg/mL
100 mcg dose = 0.1 mL

Total injection volume per dose: 0.2 mL — very manageable subQ with a 29g or 31g insulin syringe.

Monthly cost estimate: ~$60-100 for both peptides depending on source and vial size.

Solid thread. Just adding the standard caveat that these peptides are not FDA-approved for human use and GH secretagogues can have meaningful hormonal effects. Monitor IGF-1 levels if you're using these — excessively elevated IGF-1 has its own risks (association with certain cancers in epidemiological data). Stay in the physiologic range and get bloodwork.
