CJC-1295 DAC for sale listings are research-grade, not approved drugs. Learn how DAC and no-DAC forms differ, what to check in a COA, and US legal limits.
CJC-1295 DAC for sale listings are research-grade peptide vials sold for laboratory use only, not FDA-approved medicines. Sellers market the compound as a reference standard for in-vitro and animal research, and buyers are responsible for confirming purity, documentation, and legal compliance. No US pharmacy dispenses CJC-1295 DAC by prescription, and no vendor can legally sell it as a drug for human consumption.
That legal reality does not stop a steady stream of searches from people trying to understand what is actually in the vial, how the DAC version differs from the version without it, and what separates a careful supplier from a careless one. The sections below answer those questions plainly.
What CJC-1295 DAC Is
CJC-1295 is a synthetic analog of growth hormone-releasing hormone (GHRH). It was developed as a research peptide that binds to GHRH receptors and, in laboratory models, stimulates growth hormone release from the pituitary.
The DAC in the name stands for Drug Affinity Complex. That modification allows the peptide to bind covalently to albumin in blood, which dramatically slows clearance. In published pharmacokinetic work, the DAC version showed a half-life measured in days rather than minutes.
The version without the modification is usually sold as CJC-1295 No DAC, also called Modified GRF (1-29) or Mod GRF 1-29. It is a shorter, unmodified fragment with a much shorter half-life. Researchers comparing the two generally look at duration of exposure rather than potency.
CJC-1295 With DAC vs. Without DAC
Both forms appear side by side on most supplier catalogs, so it helps to know what separates them before comparing listings.
| Feature | CJC-1295 with DAC | CJC-1295 No DAC (Mod GRF 1-29) |
|---|---|---|
| Albumin binding | Yes, covalent | No |
| Reported half-life | Approximately 6 to 8 days in early studies | Roughly 30 minutes or less |
| Common catalog name | CJC-1295 DAC | CJC-1295 No DAC, Mod GRF 1-29 |
| Typical purity spec | 98% or higher by HPLC | 98% or higher by HPLC |
| Typical research focus | Sustained exposure studies | Pulsatile release studies |
Many people searching cjc-1295 with dac for sale eventually notice that the same suppliers also list the shorter fragment, which makes it useful to know what is cjc 1295 no dac used for before choosing between them. The no-DAC form is generally studied for its closer resemblance to the body's natural pulsatile growth hormone rhythm.
Anyone weighing cjc 1295 no dac for sale listings against DAC listings should treat them as two different molecules with different research profiles, not as interchangeable versions of one product.
How to Evaluate a Supplier Listing
Purity claims are easy to print and hard to verify. A cautious buyer looks for documentation rather than marketing language.
- Batch-specific certificate of analysis. The COA should match the lot number on the vial, not be a generic PDF reused across products.
- Third-party testing. Results from independent labs using HPLC and mass spectrometry carry more weight than in-house numbers alone.
- Stated purity of 98% or higher. Lower purity means more synthesis byproducts and more variability between vials.
- Cold-chain shipping. Lyophilized peptide tolerates brief ambient temperatures, but suppliers who ship with ice packs and tracking tend to be more careful overall.
- No health claims. A seller promising fat loss, muscle growth, or anti-aging results is signaling that it markets to consumers rather than laboratories.
- Clear labeling. Vials should state research use only and list the peptide name, mass, and lot number.
Legal Status in the United States
CJC-1295 is not FDA-approved for human use in the United States. It is not scheduled under the Controlled Substances Act, but selling it as a drug, supplement, or treatment is unlawful, and the FDA has issued warning letters to companies that market peptides this way.
Some states have their own restrictions on research chemicals, and importing peptide powders can trigger customs scrutiny. Buyers who order cjc 1295 peptide for sale products should confirm that laboratory possession is allowed in their jurisdiction and should never assume a listing is legal simply because it is easy to find online.
A product sold for research use only is not a consumer product. When it is repackaged, resold, or promoted for human use, that distinction collapses and the legal exposure shifts to whoever crossed the line.
Handling, Storage, and Reconstitution
Lyophilized CJC-1295 is stable for long periods when stored frozen, typically at -20°C or colder and protected from light. Repeated freeze-thaw cycles degrade peptides, so aliquoting before freezing is standard laboratory practice.
Once reconstituted, the solution is far less stable and is usually kept refrigerated and handled with sterile technique. Bacteriostatic water is common in laboratory settings because the preservative slows microbial growth, but it is not a substitute for proper aseptic handling.
Questions about dosage for cjc 1295 no dac or about the DAC version cannot be answered responsibly here. There is no FDA-approved dosing regimen, published human trials are limited, and animal study doses do not translate directly to people.
Safety Considerations and Professional Guidance
Reported effects in early human studies of GHRH analogs include injection-site reactions, flushing, and changes in blood sugar regulation. Long-term safety data for CJC-1295 in humans remains sparse.
Peptides sold online carry additional risk because identity and purity are not guaranteed. Independent testing has found vials containing the wrong peptide, less material than labeled, or bacterial contamination.
Anyone considering use for a health purpose should talk with a licensed healthcare professional rather than rely on vendor claims or forum posts. A clinician can review interactions, existing conditions, and whether an approved alternative is appropriate.
Frequently Asked Questions
Is CJC-1295 DAC legal to buy in the United States?
CJC-1295 DAC is sold legally as a research chemical for laboratory use, but it is not FDA-approved for human use and cannot lawfully be sold as a drug or supplement. It is not a federally scheduled controlled substance, though some states restrict research peptides and imported powders can draw customs attention. Buyers should verify their own state rules before ordering.
What is the difference between CJC-1295 with DAC and CJC-1295 without DAC?
The DAC version carries a Drug Affinity Complex that binds to albumin, extending its half-life to days in published pharmacokinetic studies. CJC-1295 No DAC, also called Mod GRF 1-29, lacks that modification and clears in roughly 30 minutes or less. Researchers treat them as separate molecules with different exposure profiles.
What should be on a certificate of analysis for a CJC-1295 peptide?
A credible COA should match the lot number printed on the vial and report HPLC purity, usually 98% or higher, along with mass spectrometry confirmation of the peptide's identity. Third-party laboratory testing is more trustworthy than in-house results alone. If a supplier cannot provide a batch-specific COA, the purity claim is unverifiable.
