# Best CJC-1295 Research Sources 2026 — Buying Intent Guide
Introduction
CJC-1295 has 243+ active listings on Peptides.SO alone, making it one of the most widely-sourced growth hormone secretagogues for research. Sourcing quality CJC-1295 can be overwhelming when you're evaluating multiple suppliers, variant options, and pricing tiers.
Your main decision: CJC-1295 with DAC (weekly dosing, 6-8 day half-life) or CJC-1295 No DAC (multiple daily injections, 30-minute half-life). That choice drives everything downstream—pricing, stability requirements, and protocol design.
This guide walks you through both variants, examines real pricing across our verified supplier database, and flags the quality signals that separate legitimate research suppliers from those cutting corners on testing.
What is CJC-1295? It's a synthetic analog of Growth Hormone-Releasing Hormone (GHRH), the peptide that signals your pituitary to release growth hormone. Natural GHRH has a very short half-life. CJC-1295 is engineered to persist much longer, making it a powerful research tool for studying GH secretion and growth hormone axis function.
The structural choice between DAC and No DAC determines dosing frequency and stability. Use our price comparison tool to benchmark 243+ verified listings side-by-side—a significant advantage when evaluating research peptide sources. You can identify tier-appropriate suppliers and spot outliers in seconds.

CJC-1295 Overview for Research
CJC-1295 is a Growth Hormone-Releasing Hormone (GHRH) receptor agonist. It binds to GHRH receptors on pituitary somatotroph cells and triggers endogenous growth hormone release. This makes it a valuable tool for studying the growth hormone axis, GH secretion patterns, and the metabolic effects of elevated GH.
Two forms exist with different pharmacokinetics:
CJC-1295 with DAC (Drug Affinity Complex): The DAC component is a long-chain fatty acid attached to the peptide backbone. It extends the half-life to 6-8 days, allowing once-weekly or twice-weekly dosing. Typical research doses: 1-2 mg per week. With DAC is more popular for sustained GH elevation studies because fewer injections maintain stable GH levels.
CJC-1295 No DAC (Mod GRF 1-29): Without DAC, the half-life drops to ~30 minutes. Research protocols require multiple daily injections (100-300 mcg per injection) to maintain GH elevation. No DAC is often preferred for studying acute GH secretion and pulsatile GH release, since it allows tighter temporal control over GH response.
Both forms are well-characterized in the literature. A 2006 study by Teichman et al. (PMID 16352683) characterized CJC-1295's mechanism and established dosing ranges that remain foundational for modern protocols. Additional work confirmed the peptide's selectivity for GHRH receptors and its efficacy in stimulating GH secretion.
CJC-1295 stacks well with ipamorelin (a GHRP-mimetic) for synergistic GH stimulation. Both variants reconstitute with bacteriostatic water and store long-term as lyophilized powder or in liquid form at 4°C.
Price Analysis: What You Should Pay in 2026
CJC-1295 pricing on Peptides.SO follows predictable tier patterns:
Budget tier ($40-80 per 1mg): Basic COA documentation, HPLC testing only, newer suppliers, no third-party verification.
Mid-tier ($60-120 per 1mg): Established suppliers with full COA packs (HPLC, MS, endotoxin), verification badges, responsive support.
Premium tier ($100-200+ per 1mg): Highly verified suppliers, advanced testing (NMR spectroscopy, potency assays), consistent batch quality, rapid shipping.
CJC-1295 with DAC vs. No DAC: With DAC typically commands a 20-40% premium. The DAC modification is chemically more complex and carries higher synthesis costs. Budget-tier with DAC runs $50-80/mg; premium tier reaches $150-200/mg. No DAC follows similar tier structure at lower absolute prices.
Calculate price-per-mg, not vial cost: A supplier selling 2mg for $200 is actually $100/mg, while 5mg for $300 is only $60/mg. Normalize before comparing.
Pricing red flags: CJC-1295 below $30/mg with full COAs should trigger skepticism. Quality has corners cut somewhere. Conversely, pricing above $250/mg without advanced testing or institutional relationships may simply reflect margin rather than quality.

CJC-1295 With DAC vs. No DAC: Sourcing Implications
Your choice between variants determines your sourcing strategy.
With DAC: You need suppliers who understand extended half-life peptide stability. With DAC's 6-8 day circulation, batch consistency matters more—quality variance magnifies when you dose once weekly. Seek suppliers publishing batch-to-batch stability data and maintaining strict QC. The pricing premium is justified by this consistency requirement. Lyophilized powder typically stores well at room temperature, simplifying logistics.
No DAC: You need suppliers comfortable with rapid-turnover, frequent-use protocols. No DAC's 30-minute half-life means individual dose accuracy is less critical (you redose multiple times daily anyway), but your supplier's ability to produce consistent small doses matters. Some researchers prefer No DAC specifically because it allows flexible research scheduling—you can skip a day without drastically disrupting GH levels. Reconstituted No DAC solution stability becomes crucial; seek clear storage protocols.
Peptide stability: Lyophilized CJC-1295 (both forms) is remarkably stable at room temperature when stored dry. Once reconstituted with bacteriostatic water, both remain stable for 2-4 weeks at 4°C and months at -20°C. Your supplier's reconstitution recommendations matter—some provide pre-reconstituted solutions (convenient but shorter shelf-life), others ship lyophilized powder (longer stability, slightly more work).
Choose accordingly: If your protocol requires sustained GH elevation over weeks, with DAC is the obvious choice. Prioritize suppliers with stability certifications. If you're investigating acute GH pulse dynamics or need flexible dosing, No DAC offers advantages, and you can safely choose cost-conscious suppliers so long as they maintain COA transparency.
Quality Red Flags to Avoid
1. No Certificate of Analysis (COA): Walk away. Legitimate CJC-1295 comes with HPLC purity data (target ≥95%), identity confirmation, and endotoxin testing. COAs cost money to generate—reputable suppliers include them.
2. Incomplete testing battery: HPLC alone is insufficient. Demand MS (mass spectrometry) confirmation and endotoxin testing at minimum. Premium suppliers add NMR and potency assays.
3. Suspiciously low pricing: CJC-1295 sourcing has real costs—synthesis, purification, testing, storage, compliance. Pricing below $30/mg without explanation usually indicates cut corners. Compare across verified suppliers before assuming a deal is legitimate.
4. Contamination indicators: Request storage conditions and batch age. CJC-1295 oxidizes over time; yellowed powder instead of white/off-white indicates improper storage or age. Reconstituted solutions should be clear—cloudiness suggests bacterial contamination.
5. Vague or unavailable customer support: Legitimate suppliers respond to questions about batch variability, storage, and compatibility with other compounds. If you can't reach the supplier by email or chat, that's a sourcing risk.
6. No verification or reviews on Peptides.SO: Our platform aggregates researcher reviews and testing verification. Suppliers with 0 reviews or no verification badges are unproven. Use this data to protect yourself.
7. Inconsistent batch quality: Check Peptides.SO reviews for batch-to-batch variation. If reviewers mention "batch 3 worked great but batch 5 seemed underpotent," that supplier has QC problems. Consistent quality across batches is essential.

FAQ: CJC-1295 Sourcing Questions
Q: What's the actual difference between CJC-1295 with DAC and without?
A: The Drug Affinity Complex (DAC) is a long-chain fatty acid attached to the base peptide. It extends the half-life from ~30 minutes (No DAC) to 6-8 days (with DAC) by binding to serum albumin and slowing kidney clearance. Result: with DAC requires one injection weekly; No DAC requires multiple daily injections. Both are equally legitimate for research, but sourcing logistics differ significantly.
Q: How do I know if a supplier's pricing is legitimate?
A: Check Peptides.SO for the price range across our 243+ verified listings. Mid-tier ($80-120/mg for with DAC) is standard for reputable suppliers. Get the COA first—it's the primary quality indicator. Calculate price-per-milligram and compare tier-to-tier across suppliers. Suspiciously low prices ($<30/mg) usually indicate missing testing or quality cuts. Extremely high prices ($>200/mg) without advanced testing or institutional relationships may reflect inflated margins.
Q: How can I verify a supplier's testing standards?
A: Demand the full COA. It should list:
- •Purity by HPLC (target ≥95%)
- •Identity confirmation by MS
- •Endotoxin levels (target <0.1 EU/mg)
- •Water content (typically <5%)
The supplier should reference the testing lab. Cross-reference the lab's credentials online. On Peptides.SO, verified suppliers display these credentials prominently.
Q: Why does CJC-1295 No DAC cost less than with DAC?
A: No DAC is chemically simpler—it lacks the DAC moiety requiring additional synthesis steps. Manufacturing No DAC requires less process development and fewer stabilization steps. Lower cost does NOT indicate lower purity—both variants can be ≥95% pure. The price difference reflects synthesis complexity, not quality.
Q: Is CJC-1295 legal for research?
A: CJC-1295 is a legitimate research chemical, not scheduled by the DEA in the US or most countries. It's legal to purchase and use for in vitro research and laboratory studies. Regulations vary by jurisdiction—always confirm local law before sourcing. It is NOT legal or approved for human use outside regulated clinical trials. Researchers must comply with institutional review boards (IRBs) and local research ethics protocols.
Q: What should I look for in supplier customer support?
A: Responsive suppliers answer within 24 hours about batch age, storage history, reconstitution protocols, stability timelines, and compatibility with other compounds. If you get no response or vague answers, move on. Serious suppliers have researchers on staff who understand the science.
