Current lot results against specification
Every current lot meets the release specification. Current lots test at 99.72% by HPLC-UV against a specification of ≥95%, and identity is confirmed by LC-MS on every lot.
CJC-1295/Ipamorelin components
CJC-1295 (no DAC) & Ipamorelin combines CJC-1295 (no DAC) and Ipamorelin in one vial. Each is listed with its own sequence and molecular data; the certificate reports overall purity, identity of the components and the measured amount of each.
| Component | Sequence | Formula | Molecular weight | Measured, lot KB80923 |
|---|---|---|---|---|
| CJC-1295 (no DAC) Mod GRF (1-29) |
Tyr-D-Ala-Asp-Ala-Ile-Phe-Thr-Gln-Ser-Tyr-Arg-Lys-Val-Leu-Ala-Gln-Leu-Ser-Ala-Arg-Lys-Leu-Leu-Gln-Asp-Ile-Leu-Ser-Arg-NH2 |
C152H252N44O42 | 3367.95 g/mol | 5.45 mg |
| Ipamorelin | Aib-His-D-2Nal-D-Phe-Lys-NH2 |
C38H49N9O5 | 711.87 g/mol | 5.08 mg |
Structure and modifications
The two peptides are very different in size: Mod GRF (1-29) is 3367.95 g/mol and ipamorelin 711.87 g/mol, so they separate cleanly on HPLC and are quantified individually. Ipamorelin contains three non-standard residues (Aib, D-2-naphthylalanine and D-phenylalanine).
Receptor classification
CJC-1295 (no DAC) & Ipamorelin is designed for activity at the GHRH receptor (CJC-1295 no DAC) and ghrelin receptor GHSR (ipamorelin).
Physical form
White lyophilized powder, recorded as the appearance on every certificate. Lyophilization (freeze-drying) removes water, which slows most chemical degradation. What lyophilized means.
Purity and identity specifications
Ipamorelin Labs’ stated release specification is ≥95% HPLC-UV purity with identity confirmed by LC-MS. The current lot, KB80923, reported 99.72%. How purity is measured, or how specifications fit into the quality and supply-chain process.
Analytical and testing methods
HPLC-UV for purity, LC-MS for identity and laboratory quantitation for net content, performed on every lot by Freedom Diagnostics. LAL endotoxin testing (USP <85>) and PCR microbial screening are reported for lots where they were run. Testing and quality control.
Research designation
CJC-1295 (no DAC) & Ipamorelin is designated research use only: supplied for laboratory research by qualified personnel. Research use only policy.
