Verified, lot by lot

Per lot
  • Independently tested

    Purity is quantified by reverse-phase HPLC and identity confirmed by mass spectrometry, by an outside laboratory rather than in-house.

  • A certificate for your lot

    The report that ships with your order describes the batch you received — not the product line, and not a representative sample.

  • COA-backed replacement

    If material does not match the certificate issued for its lot, we replace it or refund it. Send us the lot number and we will trace it.

  • Tracked dispatch

    Tracking is issued when the label is created, so the shipment is traceable from the moment it leaves us.

About this compound

What CJC-1295 is

C152H252N44O42

CJC-1295 without DAC is a modified GHRH fragment carrying four amino acid substitutions. Each substitution targets a site where enzymes would otherwise cleave the sequence, extending how long the molecule survives in circulation compared with unmodified GHRH. Research measures growth hormone release profiles and the shape of the resulting pulse.

How it works

How CJC-1295 works

The pathways CJC-1295 acts on, and what each one does. Signalling described from preclinical models.

GHRH Receptor Activation

GHRH-R Agonist

Four substitutions — at positions 2, 8, 15 and 27 — each block a site where enzymes would cleave native GHRH(1-29). The receptor interaction is unchanged; only the molecule's survival time is.

  • Selective for the GHRH receptor
  • Position-2 substitution blocks DPP-IV cleavage
  • Binds pituitary somatotrophs at high affinity

Pulsatile GH Secretion

Pulsatile GH

A roughly thirty-minute half-life produces discrete pulses rather than the sustained elevation the DAC variant gives. That difference is the reason both versions exist and are studied separately.

  • Half-life around 30 minutes without albumin binding
  • Produces discrete rather than sustained release
  • Peak response within 15-30 minutes

GH/IGF-1 Axis Stimulation

IGF-1 Axis

Each pulse drives a transient rise in hepatic IGF-1. Because exposure is brief, the IGF-1 profile differs markedly from the prolonged elevation reported with the DAC variant.

  • IGF-1 rises transiently with each pulse
  • Cortisol and prolactin unaffected
  • Studied alongside ghrelin-receptor secretagogues

Uses & applications

What CJC-1295 is researched for

The main areas under study, and the study-reported figures behind them.

Endocrinology

Pulsatile GH Research

The short half-life is the feature here: it produces discrete pulses, which is what makes the compound useful for studying release pattern rather than total exposure.

Teichman et al. 2006

Pharmacology

GHRH Analog Comparison

Most often studied head-to-head against the DAC variant, where the only meaningful variable is duration of action.

Frohman et al. 2003

Combination Research

CJC / Ipamorelin Synergy

Combination work pairs it with a ghrelin-receptor agonist to test whether engaging two receptor populations amplifies the pulse.

Raun et al. 1998

Animal Models

GHRH Axis Restoration

Animal models examine whether upstream stimulation restores a release pattern closer to normal physiology than exogenous growth hormone does.

Alba et al. 2006

What the published work measures

The endpoints reported across the literature for this compound. The figures belong to the individual papers, not to us.

  • Half-Life vs Native GHRH(1-44)
  • DPP-IV Protease Resistance
  • GHRH-R Binding Affinity vs Native GHRH
  • Selectivity — Cortisol / Prolactin Effect

FAQ

Common questions about CJC-1295

What is CJC-1295?

+

CJC-1295 without DAC is a modified GHRH fragment carrying four amino acid substitutions. Each substitution targets a site where enzymes would otherwise cleave the sequence, extending how long the molecule survives in circulation compared with unmodified GHRH. Research measures growth hormone release profiles and the shape of the resulting pulse.

What is CJC-1295 researched for?

+

Published research on CJC-1295 concentrates on Pulsatile GH Research, GHRH Analog Comparison, CJC / Ipamorelin Synergy and GHRH Axis Restoration. Each of those areas is summarised further up this page with the citation it comes from, and the full reference list — 4 indexed publications — sits at the bottom. Study designs and concentrations vary considerably between publications, so the primary sources are worth reading directly.

How does CJC-1295 work?

+

The literature describes CJC-1295 acting across GHRH Receptor Activation, Pulsatile GH Secretion and GH/IGF-1 Axis Stimulation, reported respectively as GHRH-R Agonist, Pulsatile GH and IGF-1 Axis. Those pathways are drawn from preclinical models rather than clinical work, and they describe what has been observed rather than a settled mechanism — the individual pathway cards above cite what each one is based on.

What are the molecular specifications for CJC-1295?

+

CJC-1295 has a molecular formula of C152H252N44O42 and an average mass of 3367.97 g/mol. It is indexed under CAS 863288-34-0. It ships as lyophilized powder. Those are nominal reference values for the parent compound. The identity of the specific material you receive is confirmed by mass spectrometry and reported on that lot's certificate.

How should CJC-1295 be stored and reconstituted?

+

Store the sealed vial at -20°C, protected from light and moisture, and let it reach room temperature before opening so condensation does not form on cold powder. CJC-1295 is water-soluble; reconstitute by directing the diluent down the vial wall rather than onto the powder, then swirl to dissolve rather than shaking. Keep reconstituted solution refrigerated and avoid repeated freeze-thaw cycles — solutions are far less stable than lyophilized powder.

Is CJC-1295 approved for human use?

+

No. CJC-1295 is supplied strictly for in-vitro laboratory research and development. It is not a drug, food, supplement or cosmetic, it has not been evaluated by the FDA, and it is not intended for human or animal consumption, ingestion, injection or any in-vivo use. Ordering confirms you are a qualified researcher or institution purchasing on that basis.
