Specification and laboratory information
CJC-1295 with DAC 10mg is supplied as a lyophilised peptide for laboratory and analytical research. This listing is for the DAC form; check the compound identity and matching batch document when comparing products.
Laboratory and analytical research only. Not for human consumption. Orders restricted to adults aged 18 or over.
CJC-1295 is one of the most commonly mislabelled compounds in this market.
This is CJC1295 with DAC.
Two distinct molecules share the name, and the CAS number most suppliers publish belongs to the wrong one.
- With DAC — 30 residues, ~3647 g/mol. The C-terminal lysine carries a maleimidopropionyl group (the drug affinity complex).
- Without DAC (also sold as Mod GRF 1-29) — 29 residues, ~3368 g/mol. No conjugation.
This product is the 30-residue with DAC-conjugated compound.
Check the mass on your COA: ~3647 confirms DAC, ~3368 means you have the non-DAC analogue.

Storage and handling
Store the sealed vial desiccated at −20°C, protected from light. The maleimide group is the reactive feature of this molecule and is susceptible to hydrolysis — keep the powder dry and avoid repeated freeze-thaw cycles. Equilibrate to ambient temperature before opening.
Supply and despatch
UK tracked delivery is free. Paid orders for available stock placed before 3pm UK time on a working day are normally dispatched the same day. See our delivery information for details.
Frequently asked questions
What's the difference between CJC-1295 with and without DAC? The DAC version has a maleimidopropionyl group on a 30th C-terminal lysine residue; the non-DAC version is the 29-residue peptide alone. Masses are ~3647 and ~3368 g/mol respectively.
What is the correct CAS number for CJC-1295 with DAC? 446262-90-4. The widely published 863288-34-0 properly denotes the 29-residue non-DAC compound — a frequent source of confusion when comparing suppliers.
How do I confirm which version I've received? Check the mass on the lot COA against ~3647 g/mol.
Is this the same as Mod GRF 1-29? No. Mod GRF 1-29 is the non-DAC 29-residue compound.
