About CJC-1295 + Ipamorelin

CJC-1295 (a GHRH analogue) combined with Ipamorelin (a selective GHRP) creates a synergistic growth hormone secretagogue blend. Each vial contains 5mg CJC-1295 + 5mg Ipamorelin, both ≥98% HPLC purity, co-lyophilised.

In-depth guide

CJC-1295 + Ipamorelin 5+5mg — research overview, mechanism & protocol guidance

The CJC-1295 + Ipamorelin co-lyophilised blend is the gold-standard GHRH/GHRP research combination — a long-acting growth hormone releasing hormone analogue paired with a selective growth hormone releasing peptide. UK Peptides supplies a 5mg + 5mg blend at ≥98% HPLC purity on both peptides, with a third-party Certificate of Analysis verifying each component separately.

What is the CJC-1295 + Ipamorelin blend?

This vial contains two co-lyophilised research peptides: CJC-1295 (without DAC), a 30-amino-acid tetra-substituted GHRH analogue with extended half-life, and Ipamorelin, a pentapeptide selective growth hormone secretagogue receptor (GHSR) agonist. Combined, they form the most widely cited GHRH + GHRP research blend in the published growth-hormone literature, used to study additive and synergistic GH pulse amplitude in pituitary and somatotroph cell models.

Mechanism — why GHRH and GHRP are studied together

CJC-1295 binds the GHRH receptor on pituitary somatotrophs, increasing baseline GH pulse amplitude. Ipamorelin binds the separate ghrelin/GHSR receptor, triggering a complementary GH release pulse without significantly affecting prolactin, ACTH or cortisol — a notable selectivity advantage over older GHRPs such as GHRP-6. Combining the two engages both upstream pathways simultaneously, producing a larger and more physiological GH research signal than either peptide alone.

Research applications for the GHRH/GHRP blend

Published research using CJC-1295 and Ipamorelin individually or in combination covers somatotroph signalling and GH pulse studies, IGF-1 axis modulation, in-vitro pituitary cell research, sleep architecture and slow-wave sleep modelling, body composition research in animal models, recovery and tissue repair studies, and comparative pharmacology against other GHRH analogues (sermorelin, tesamorelin) and GHRPs (hexarelin, GHRP-2, GHRP-6).

Reconstitution and stability

Store the lyophilised vial at -20°C, sealed and protected from light. Reconstitute with bacteriostatic water (0.9% benzyl alcohol) — typically 2ml per 10mg blend. Add solvent down the side of the vial; do not shake. Once reconstituted, refrigerate at 2–8°C and use within 28 days. Both peptides in the blend remain stable in solution under refrigeration; do not refreeze.

Dual-peptide CoA — verified separately

The Certificate of Analysis for this blend reports HPLC-UV purity and mass-spectrometry identity for CJC-1295 and Ipamorelin as separate analytical entries, each verified to ≥98% purity. Janoshik Analytical or Aspen Bioanalytics signs each batch CoA. The lot number on the vial sticker matches the CoA exactly — co-lyophilised vials are not pooled or relabelled.

Why UK Peptides for CJC-1295 + Ipamorelin

Co-lyophilised blends are particularly vulnerable to substitution and under-dosing on the grey market because the analytical separation requires more sophisticated HPLC method development than a single-peptide vial. UK Peptides addresses this with two-component independent verification on every lot, UK stock, same-day Manchester dispatch and full lot traceability.

Storage & handling

Keep it stable, keep it sterile

Storage: Store lyophilised powder at -20°C in a sealed vial. Protect from light and moisture. Allow the vial to reach room temperature before opening to prevent condensation entering the vial. Do not store in a frost-free freezer. Reconstitution: Reconstitute using bacteriostatic water (0.9% benzyl alcohol). Add solvent slowly down the side of the vial — do not shake. Allow to dissolve gently at room temperature. Reconstituted stability: Once reconstituted, store at 2–8°C (refrigerated). Use within 28 days. Do not refreeze after reconstitution. Shipping: All vials are dispatched in insulated mailers with ice packs to maintain cold chain during Royal Mail Tracked 24 transit.

    "Third order of CJC-1295 + Ipamorelin from UK Peptides and the consistency is remarkable. HPLC trace matches the certificate to two decimal places, batch numbers match the vial sticker, no surprises. This is how it should be done."

    "Independent verification on a sample of the CJC-1295 + Ipamorelin lot confirmed the stated purity within margin of error. Documentation, packaging and cold chain were all faultless. Switched my entire group over from a US supplier last quarter."
