Summary: CJC-1295 is a synthetic analog of growth hormone-releasing hormone (GHRH 1-29), available in two configurations: with DAC (Drug Affinity Complex) and without DAC (also known as MOD GRF 1-29). PeptideDropship supplies research-grade CJC-1295 in both forms to verified B2B partners under strict research-use-only labeling. 99%+ purity verified by HPLC and mass spectrometry, third-party COAs per batch. For research use only — not for human consumption.
Two configurations available
PeptideDropship supplies CJC-1295 in two distinct configurations. Partners should specify the configuration when ordering.
CJC-1295 with DAC
| Parameter | Value |
|---|---|
| Peptide name | CJC-1295 with DAC (Drug Affinity Complex) |
| Type | Modified GHRH (1-29) analog with maleimidopropionyl-lysine modification |
| Molecular formula | C₁₆₅H₂₆₉N₄₇O₄₇ |
| Molecular weight | ~3647.20 g/mol |
| CAS number | 863288-34-0 |
| Form | Lyophilized white powder |
| Standard pack sizes | 2 mg, 5 mg vials |
CJC-1295 without DAC (MOD GRF 1-29)
| Parameter | Value |
|---|---|
| Peptide name | CJC-1295 without DAC (MOD GRF 1-29) |
| Type | Modified GHRH (1-29) analog without lysine-DAC modification |
| Molecular formula | C₁₅₂H₂₅₂N₄₂O₄₂ |
| Molecular weight | ~3367.95 g/mol |
| CAS number | 863288-34-0 (related) |
| Form | Lyophilized white powder |
| Standard pack sizes | 2 mg, 5 mg, 10 mg vials |
Both configurations are stored at −20°C lyophilized and 2–8°C after reconstitution.
Manufacturing and quality control
Both configurations are produced through solid-phase peptide synthesis (SPPS) and independently verified by third-party analytical laboratories before release.
Standard analytical verification on every batch:
- Mass spectrometry: confirms molecular weight matches the specific target configuration (with or without DAC)
- Reverse-phase HPLC: quantifies purity to the 99%+ partner-grade standard
- Counterion content: documented salt form (typically TFA)
- Water content: Karl Fischer titration
- Endotoxin testing: LAL test available on request
The full COA accompanies every shipment with batch number, manufacture date, lab partner, analytical methodology, and acceptance criteria.
Wholesale availability
- No minimum order quantity on either configuration
- Tiered pricing — per-unit cost decreases with monthly volume
- 24-hour fulfillment from US-based warehouse
- API integration available for automated order routing
- Configuration-specific stock — both DAC and non-DAC variants tracked separately in the partner portal
White-label and private-label options
- Generic: PeptideDropship-branded packaging — fastest path
- White-label: custom labels, packaging, inserts under your brand. Configuration specified clearly on each label
- Private-label: custom pack sizes or custom formulation. Higher minimums apply (typically 100–500 units)
Because CJC-1295 has two distinct configurations, white-label and private-label orders must clearly specify which variant (with DAC vs. without DAC) the labels and packaging are intended for. Mislabeled product is a compliance risk for the reseller.
See the white-label vs. private-label guide for the full comparison.
Packaging and shipping
Both configurations ship as lyophilized powder in sealed amber vials with tamper-evident closure. Configuration (with DAC or without DAC) is clearly labeled on every vial.
Each shipment includes the batch-specific COA — physical with the order or electronic PDF automatically delivered on confirmation. Cold-chain shipping is available; both configurations are stable in lyophilized form at room temperature for short-duration transit.
Compliance and labeling
CJC-1295 is supplied to verified B2B partners exclusively for research use under strict research-use-only labeling. Resellers and end users are responsible for maintaining the labeling, FDA disclaimer, and compliance with state, local, and international regulations governing research-peptide distribution.
The two configurations (with DAC vs. without DAC) are not interchangeable in research applications and have meaningfully different chemistry. Partners are responsible for clear and accurate labeling of which configuration is being supplied to their end customer.
FAQ
What’s the difference between CJC-1295 with DAC and without DAC?
The DAC (“Drug Affinity Complex”) variant includes an additional maleimidopropionyl-lysine modification that significantly extends the molecule’s serum half-life. The two are distinct compounds with different molecular weights, different chemistry, and different research applications. They are not interchangeable.
Which configuration is more commonly ordered?
Demand varies by partner. Research-supplier partners typically order both configurations; brand-focused resellers usually specialize in one. PeptideDropship supplies both at standard wholesale pricing.
What’s the standard purity?
99%+ purity verified by reverse-phase HPLC and confirmed by mass spectrometry on every batch. The COA confirms the specific configuration via molecular-weight verification.
Can I order both configurations under one partner account?
Yes. Verified partners have access to both configurations from the same partner portal.
How is CJC-1295 stored?
Lyophilized at −20°C for long-term stability. After reconstitution, store at 2–8°C and use within the documented stability window appropriate to the research application.
Are sample COAs available?
Yes. Verified partners can request representative COAs from recent batches of either configuration before placing an order.
Get started
Verified B2B partners can apply for partner access. Verification typically completes within 1–3 business days. For business model context, see the peptide dropshipping guide.
