Why These Two Compounds Are Blended

CJC-1295 and Ipamorelin are structurally unrelated. They share no sequence homology, differ in length by a factor of nearly six, and engage entirely different receptors. They are supplied together because that difference is the point — not because they are variations on a theme.

CJC-1295 is a 29-residue sequence derived from the N-terminal fragment of growth hormone-releasing hormone, GRF(1–29), carrying four amino acid substitutions relative to the native fragment. Those substitutions target known enzymatic cleavage sites and sites of chemical instability. It acts at the GHRH receptor.

Ipamorelin is not derived from any natural sequence. It is a fully synthetic pentapeptide built from unusual building blocks: Aib (aminoisobutyric acid, a non-proteinogenic residue), D-2-naphthylalanine and D-phenylalanine — two D-amino acids, the mirror-image stereoisomers of the L-forms found in natural proteins. Its C-terminus is amidated. Every one of those features exists to resist enzymatic degradation, since proteases that recognise natural L-amino acid sequences do not efficiently process D-residues. It acts at the ghrelin receptor (GHS-R1a), a different receptor entirely from CJC-1295’s target.

Two compounds engaging two separate receptors is a distinct experimental design from two compounds engaging the same receptor, and it is the reason this pairing is supplied pre-combined rather than as a variation on either single compound.

A note on DAC. CJC-1295 exists in two forms: with and without a drug affinity complex, a maleimide group that binds serum albumin and substantially extends circulating half-life. The DAC and non-DAC forms have materially different molecular weights and are frequently conflated by suppliers. Check the Certificate of Analysis on anything you purchase.

Handling & Storage

Lyophilized material is stable at 2–8°C when sealed and shielded from light. For storage beyond several months, -20°C is preferred. Avoid repeated freeze-thaw cycles.

Purity & Testing

Every batch is synthesized at our GMP-compliant Arizona facility and independently analyzed by Freedom Diagnostics before release. For blends, each component is verified separately prior to combination and the finished blend is verified again. Certificates of Analysis are available for any lot; contact us with your order number.

Frequently Asked Questions

What is in this blend?
CJC-1295 (5mg) and Ipamorelin (5mg), totaling 10mg of peptide content in a single vial.

Does this contain CJC-1295 with or without DAC?
Check the Certificate of Analysis for your specific lot. The two forms have different molecular weights and are commonly confused across the market.

What are D-amino acids and why does Ipamorelin contain them?
D-amino acids are the mirror-image stereoisomers of the L-forms found in natural proteins. Proteases that recognise L-sequences process them poorly, so incorporating D-residues is a standard strategy for resisting enzymatic degradation.

What is Aib?
Aminoisobutyric acid, a non-proteinogenic amino acid. It constrains backbone conformation and is not found in natural protein sequences.

Do the two components target the same receptor?
No. CJC-1295 acts at the GHRH receptor; Ipamorelin acts at the ghrelin receptor, GHS-R1a.
