Growth Hormone & IGF · Long-acting GHRH analogue research

CJC-1295 (with DAC)

Scientific Product Dossier

CJC-1295 with DAC is an albumin-binding, long-acting growth-hormone-releasing-hormone analogue. Two early randomized studies in healthy adults reported sustained GH and IGF-1 increases and an estimated half-life of 5.8–8.1 days. Those values depend on the DAC form and must not be assigned to without-DAC material. FDA reports limited clinical data and serious adverse-event reports.

Mechanism of action

How CJC-1295 (with DAC) is studied

A target-to-pathway view grounded in the linked research records.

Albumin-binding design

The drug-affinity-complex group enables covalent association with endogenous albumin and prolonged exposure.

Sustained GH/IGF-1 response

Small human studies measured prolonged pharmacodynamic increases rather than clinical performance outcomes.

Reported research findings

What published studies report about CJC-1295 (with DAC)

Reported outcomes are paired with their experimental model and evidence boundary.

Human PK/PD

Sustained endocrine response

Mean GH rose 2- to 10-fold for at least 6 days and mean IGF-1 rose 1.5- to 3-fold for 9–11 days; estimated half-life was 5.8–8.1 days.

Healthy adults, short ascending-dose studies, DAC form only.

FDA review

Current safety concerns remain

FDA identifies limited clinical data, immunogenicity/impurity concerns and serious reports including increased heart rate and systemic vasodilation.

FDA lists CJC-1295 generically in this public summary and does not resolve the marketed DAC/without-DAC form. It is not a finding about a specific catalog lot.

Healthy-adult randomized studies · 2006

Long-acting CJC-1295: measured endocrine response

Two placebo-controlled studies lasted 28 and 49 days. After a single administration, mean GH increased approximately 2–10-fold for at least 6 days and IGF-I approximately 1.5–3-fold for 9–11 days.

These were pharmacokinetic and endocrine endpoints in adults aged 21–61. They do not establish long-term outcomes, and they must not be assigned to CJC-1295 without DAC.

Analytical interpretation

Interpret the documents, not just the headline number.

Use the source-reviewed guide to separate chromatographic area purity, quantitative assay, LC-MS identity, composition and stability evidence before comparing variants or requesting a lot record.

Research FAQ

CJC-1295 (with DAC) questions

Concise answers for researchers comparing identity, evidence and catalog variants.

What does DAC change?

The drug-affinity-complex group supports albumin binding and prolonged exposure; it is the defining feature behind the published multi-day pharmacokinetics.

Can the 5.8–8.1 day half-life be used for without-DAC material?

No. That estimate belongs to the albumin-binding form studied in the paper.

How is product identity verified?

Family-level identifiers organize the catalog, while the applicable product specification and lot-specific COA control the supplied form, identity and release results.

Which quality documents can be requested?

A lot-specific COA, product specification sheet and analytical method summary can be requested where applicable.

How should CJC-1295 (with DAC) be stored?

Store at -20 °C, protected from light and moisture. After reconstitution, aliquot and avoid repeated freeze-thaw cycles. Confirm the applicable storage statement on the product-specific specification and lot documentation.
