Overview
CJC-1295 and Ipamorelin are two synthetic peptides frequently studied in growth-hormone secretagogue research, often together. PX-Labs offers them individually, as a combined blend, and in a long-acting DAC variant. This article clarifies what each is, how the variants differ, and why the distinction between them matters in research.
CJC-1295
CJC-1295 is a synthetic peptide — a modified analog of the growth-hormone-releasing hormone fragment GRF(1-29). The structural modifications improve its stability relative to the native fragment.
Available from PX-Labs: CJC-1295 — 5mg, 10mg.
CJC-1295 DAC
The DAC (Drug Affinity Complex) variant adds a modification that binds to serum albumin, extending the peptide’s circulating half-life. This makes CJC-1295 DAC a structurally distinct, longer-acting compound compared to standard CJC-1295 — an important distinction in research where half-life is a study variable.
Available from PX-Labs: CJC-1295 DAC — 2mg, 5mg.
Ipamorelin
Ipamorelin is a synthetic peptide classified as a selective growth-hormone secretagogue. It belongs to a different structural class than CJC-1295 and is frequently studied alongside it.
Available from PX-Labs: Ipamorelin — 5mg, 10mg.
The CJC-1295 + Ipamorelin Blend
Because the two are so often examined together, PX-Labs offers them combined in a single vial as CJC-1295 + Ipamorelin. They belong to different secretagogue classes, which is precisely why combination studies are of interest — examining whether engaging the two pathways together differs from either alone.
Choosing Between the Variants in Research
The three CJC-related products are not interchangeable:
- CJC-1295 — the base GRF(1-29) analog
- CJC-1295 DAC — the long-acting variant (albumin-binding, extended half-life)
- CJC-1295 + Ipamorelin — the combination blend with a separate secretagogue
The right choice depends on the study design — particularly whether half-life or combination effects are the variable under examination.
