CJC-1295 Without DAC Wholesale — Growth Hormone Peptide Sourcing Guide

CJC-1295 without DAC (also called Mod GRF 1-29) has a short half-life of approximately 30 minutes in research models, which makes it fundamentally different from CJC-1295 with DAC — and if your wholesale supplier doesn’t clearly distinguish between the two on COAs, walk away.

If you’re sourcing CJC-1295 without DAC for wholesale, you’re participating in one of the largest sub-segments of the peptide market. The “without DAC” variant (Drug Affinity Complex removed) is the research standard because it produces a more natural pulsatile growth hormone release pattern in experimental models. The “with DAC” variant has a half-life of several days and a completely different research application profile. Confusing the two isn’t a minor labeling error — it’s a fundamental product mismatch.

CJC-1295 Without DAC vs With DAC — Why Wholesale Buyers Must Know the Difference

The practical difference for wholesale buyers is that CJC-1295 without DAC commands 20-30% higher volume demand than the DAC variant, so stocking the wrong form means sitting on inventory that moves much slower.

The key distinction in simple terms:

• Without DAC (Mod GRF 1-29): Half-life ~30 minutes, researched for pulsatile GH release patterns. This is what 80%+ of your CJC-1295 buyers are looking for.
• With DAC: Half-life ~6-8 days, researched for sustained GH elevation. Much smaller buyer base, primarily specialized endocrine labs.
• Molecular weight difference: Without DAC is approximately 3367 Da; with DAC adds roughly 300 Da. Mass spectrometry easily distinguishes between the two.

If your supplier’s COA doesn’t specify “without DAC” or “Mod GRF 1-29” explicitly, and only lists “CJC-1295,” that’s a red flag. Reputable manufacturers distinguish between the two forms on every document.

Quality Standards for CJC-1295 Without DAC Wholesale

CJC-1295 without DAC should test at 98%+ purity via HPLC, with a single sharp peak and no evidence of DAC-conjugated variant in the mass spectrometry trace — contamination with the DAC variant is more common than most buyers realize.

The 30-amino-acid sequence of Mod GRF 1-29 makes it moderate in synthesis difficulty. Key quality checks:

1. HPLC purity ≥ 98% — Standard for this peptide class

2. Mass spectrometry confirms 3367 Da (±1 Da) — Rules out the DAC variant

3. No dimer or aggregate peaks — GHRH analogs can form dimers during improper lyophilization, appearing as secondary peaks at roughly double the molecular weight

4. Consistent fill weight — At 2mg or 5mg per vial, accuracy within ±5% is the industry standard

How CJC-1295 Without DAC Is Used in Research Contexts

In research settings, CJC-1295 without DAC is almost always studied in combination with a GHRP (Growth Hormone Releasing Peptide) like Ipamorelin, not as a standalone compound — this is why wholesale buyers who also stock Ipamorelin consistently outsell those who don’t.

The standard research combination of CJC-1295 without DAC + Ipamorelin creates a synergistic effect on growth hormone pulse amplitude in experimental models. For wholesale strategy, this means:

• Bundle CJC-1295 with Ipamorelin — Buyers almost always need both, and a supplier who offers them as a bundle captures more wallet share
• Stock at matched ratios — If you’re buying 100 vials of CJC-1295, plan for 100 vials of Ipamorelin as well
• Ensure both products come from the same manufacturer — Cross-contamination risk is lower when both peptides are produced in the same facility

FAQ

What’s the shelf life of lyophilized CJC-1295 without DAC?

Vacuum-sealed lyophilized CJC-1295 without DAC is stable for 12-18 months at room temperature, and 24+ months refrigerated. After reconstitution with bacteriostatic water, refrigerate (2-8°C) and use within 28 days.

Is CJC-1295 without DAC more expensive than the DAC variant?

Surprisingly, no — CJC-1295 without DAC is typically priced similarly to or slightly below the DAC variant at wholesale because the higher production volume drives economies of scale.

Can I order custom dosages for CJC-1295 without DAC wholesale?

Yes, most peptide manufacturers offer custom vial dosages (2mg, 5mg, 10mg) at minimum order quantities of 50-100 vials. The 5mg format is the most popular for research applications.

Does CJC-1295 need cold-chain shipping?

No — lyophilized CJC-1295 without DAC ships safely at ambient temperature for transit times under 3 weeks, as long as vials maintain vacuum seal. Cold-chain is only needed for reconstituted peptide.
