The CJC-1295 / Ipamorelin blend is a popular combination in growth-hormone axis research. This page covers what it is, the research areas it appears in, and how to source it with documentation from Australian stock.
What is CJC-1295 / Ipamorelin Blend?
This is a combination preparation pairing a GHRH-analogue (CJC-1295) with a selective growth-hormone signal (Ipamorelin), studied together for their complementary action.
The logic of the pairing is that the growth-hormone axis has two independent entry points, and each component addresses a different one:
- CJC-1295 acts on the GHRH receptor — the body's own "release" instruction. It is based on a shortened fragment of growth-hormone-releasing hormone, modified to resist the enzyme that would otherwise clear it within minutes.
- Ipamorelin acts on the ghrelin receptor (GHS-R) — a separate receptor on a separate pathway. It is a five-amino-acid peptide characterised by acting selectively, without the cortisol and prolactin spillover seen in earlier compounds of its class.
Because these are genuinely different receptors rather than two routes to the same one, the components are not substitutes for each other and don't compete for the same binding site. That's the entire reason the combination exists as a research preparation: it allows both pathways to be engaged at once and studied together, rather than requiring two separately prepared vials.
Why blends are studied as a category
Combination preparations are common in this field, and they raise a research question that single compounds don't: whether the combined result differs from what you'd predict by adding the two individual results together. That's the distinction between an additive and a synergistic interaction, and it can only be examined by studying the components both separately and together.
It also introduces a practical complication worth understanding. With a blend, a Certificate of Analysis has more work to do — a purity figure alone doesn't establish the ratio between the two components, and the ratio is what defines the preparation. Our guide to peptide blends explained covers how these preparations are put together and what to check.
Research areas
In the scientific literature, CJC-1295 / Ipamorelin Blend is studied in relation to:
- Growth-hormone axis research
- Combined GHRH + ghrelin-receptor research
- Recovery and body-composition research
- Additive and synergistic interaction research
- Endocrine and pituitary-signalling research
These describe fields of scientific study — they are not claims about effects in humans. Nothing here should be read as a statement about what the preparation does in a person; NextGen Peptides supplies it strictly for laboratory and in-vitro research use.
Storage & handling
Supplied as a lyophilised (freeze-dried) powder. Store at −20°C; reconstitute with bacteriostatic water and refrigerate. See our full guide to storing and reconstituting research peptides, and what to mix it with in our bacteriostatic water guide.
Blends warrant slightly more care than single compounds, for one specific reason: the two components are not identical molecules and don't necessarily degrade at the same rate. Rough handling doesn't simply reduce potency evenly — it can shift the ratio between them, which is the one property that defines the preparation. Reconstitute by running diluent slowly down the inside wall of the vial and swirling until dissolved, never shake, refrigerate at 2–8°C once mixed, keep vials boxed and out of light, and never refreeze a reconstituted solution.
Note also that concentration figures refer to the total peptide content, not to either component individually. Our reconstitution calculator works out total concentration from vial size and diluent volume.

Common questions about CJC-1295 / Ipamorelin Blend
What is the CJC-1295 / Ipamorelin blend?
A combination preparation pairing a GHRH-analogue (CJC-1295) with a selective growth-hormone secretagogue (Ipamorelin), studied together for their complementary receptor activity. Supplied for laboratory research use only.
What research areas is it studied in?
Growth-hormone axis research, combined GHRH-receptor and ghrelin-receptor research, and recovery and body-composition research. These are fields of study, not effects in humans.
Is the blend tested and does it come with a CoA?
Yes. Every batch is independently tested for purity (RP-HPLC) and identity (LC-MS), with the Certificate of Analysis published.
Is it held in Australian stock?
Yes. We hold the CJC-1295 / Ipamorelin blend in Australian stock and dispatch same or next business day for orders placed before the daily cut-off.
Why are these two compounds combined?
Because they act on two independent receptors — CJC-1295 on the GHRH receptor, Ipamorelin on the ghrelin receptor. They aren't substitutes competing for the same binding site, so the combination engages both pathways at once.
How is CJC-1295 different from Tesamorelin?
Both act on the GHRH receptor, but Tesamorelin is a stabilised copy of the full 44-amino-acid natural sequence, while CJC-1295 is based on a shortened fragment. See our comparison.
What should I check on a CoA for a blend?
More than for a single compound. A purity figure alone doesn't establish the ratio between the two components, and the ratio is what defines the preparation. See peptide blends explained and our testing standards.
How long does a reconstituted vial last?
Generally around four weeks refrigerated at 2–8°C when reconstituted with bacteriostatic water. Unreconstituted powder at −20°C keeps far longer. Never refreeze a reconstituted solution.
Does the concentration refer to each component?
No — stated figures are total peptide content, not either component individually.
