CJC-1295 comes in two forms — DAC (Drug Affinity Complex, 6-8 day half-life) and no-DAC (also called Mod GRF 1-29, ~30 minute half-life). They're priced similarly but dosed very differently, and vendors sometimes mislabel one as the other. Research pricing runs from $7/mg to $50/mg for the same molecule, driven almost entirely by vial size and vendor markup. Community protocols have grown around mod GRF 1-29 + ipamorelin stacks, so dual-peptide buying is the norm.
This guide covers what you should actually pay per milligram, which vial size matches your protocol (no-DAC vs DAC dosing is radically different), and how to verify a COA for both forms. CJC-1295 is a 30-amino-acid GHRH analog with D-Ala, Gln, Ala, and Leu substitutions at positions 2, 8, 15, and 27 — a legitimate vendor will confirm all four on their COA.

Understanding CJC-1295 Pricing
CJC-1295 is sold as a lyophilized powder in sealed glass vials. The two forms (DAC and no-DAC) trade at similar per-mg prices because synthesis costs are comparable — the price spread comes mostly from vendor markup, vial size, and whether the vendor invests in third-party testing.
Current Market Pricing (2026)
2 mg
$35-50
$17.50-25/mg
Short no-DAC trial (~3 weeks at 100 mcg/day)
5 mg
$35-85
$7-17/mg
Standard — most popular size
10 mg
$66-140
$6.60-14/mg
Long protocols, best $/mg
The pattern is clear: 5mg is the sweet spot for virtually every CJC-1295 protocol — both DAC (2.5-5 week supply at 1-2 mg/week) and no-DAC (with reconstitution splitting). 10mg vials save an additional 5-15% per mg.
Cheapest single-vial option: Ion Peptide's 15% off drops the 5mg vial to $24.65 ($4.93/mg effective) — the lowest effective price we track for buying one vial. Get the code →

CJC-1295 no-DAC (Mod GRF 1-29) protocols:

How to Verify CJC-1295 Quality
CJC-1295 is a 30-amino-acid synthetic GHRH analog with four modifications to resist degradation: D-Ala at position 2 (prevents DPP-IV cleavage), Gln at position 8 (prevents asparagine rearrangement), Ala at position 15 (enhances bioactivity), and Leu at position 27 (prevents methionine oxidation). The DAC form adds a maleimidopropionic acid (MPA) linker that covalently binds albumin, extending half-life from ~30 minutes to 6-8 days. A cheap synthesis that skips any of the four substitutions produces a less stable peptide that behaves more like native GHRH.
What a COA (Certificate of Analysis) Should Include
Identity Confirmation
Mod GRF 1-29 (no-DAC): 3,368.7 Da
CJC-1295 DAC: ~3,647 Da (includes MPA linker)
Amino acid sequence verification with the four modifications at positions 2, 8, 15, and 27
For DAC form: confirmation of the MPA conjugation
Purity Testing
HPLC purity — look for 98%+ purity
The chromatogram should show a single dominant peak
Contamination Testing
Endotoxin levels (bacterial contamination)
Residual solvent analysis (acetonitrile, TFA)
Heavy metals screening
How to Verify a COA Is Legitimate
Check the testing lab — Reputable labs include Janoshik Analytical, MZ Biolabs, and Colmaric Analyticals. Avoid vendors who only show "in-house" testing.
Verify on the lab's website — Janoshik COAs have a task number you can look up directly at janoshik.com.
Check the date — COAs should be recent (within 6 months).
Match the batch — The batch/lot number on the COA should match what's printed on your vial.
Look for the original PDF — Screenshots are easier to fake than full PDFs with lab letterhead and signatures.
Red Flags to Avoid
No COA available — any vendor unwilling to provide testing results is not worth the risk
DAC vs no-DAC labeling is unclear — they're different molecules with different dosing; vendors must label clearly
Only in-house testing — self-reported purity numbers are meaningless
Prices well below $6/mg — implausible for correctly-synthesized material with all four substitutions
No contact information — legitimate vendors have real customer service
No return or reship policy — reputable vendors stand behind their products
