CJC-1295 with DAC
research guide
CJC-1295 with DAC is a modified growth hormone releasing hormone analog attached to a drug affinity complex intended to extend its activity beyond the very short half-life of natural GHRH. In a published trial, healthy adults given a single subcutaneous dose showed dose-dependent increases in growth hormone lasting 6 days or more and in IGF-1 lasting 9 to 11 days, with IGF-1 remaining elevated for up to 28 days after multiple doses; the study itself ran for 28 and 49 days to capture these effects [1]. It has no FDA-approved indication and is not evaluated to the standard of an approved drug.
Evidence depends on population and formulation. Literature summary, not clinical peer review.

01 · Start with identity
What is CJC-1295 with DAC?
CJC-1295 with DAC refers to the specific GHRH-analog-plus-affinity-complex molecule studied in the cited pharmacology trial, developed by a pharmaceutical sponsor for that research program. Reign Peptide's product is a separately manufactured research-chemical vial of the same class labeled for laboratory use, with no confirmed identity match, purity certification tie, or sponsor relationship to the studied compound.

02 · Read the evidence
What the studies reported
01
Duration of GH and IGF-1 elevation after a single dose
After a single subcutaneous injection, CJC-1295 with DAC produced dose-dependent increases in mean plasma growth hormone of 2- to 10-fold lasting 6 days or more, and increases in mean plasma IGF-1 of 1.5- to 3-fold lasting 9 to 11 days; the estimated half-life of the compound itself was 5.8 to 8.1 days. [1]
02
Effect of repeated dosing and overall study design
The trial used two randomized, placebo-controlled, double-blind ascending-dose designs, one running 28 days and one running 49 days, to allow both single-dose and multiple-dose assessment; after multiple doses, mean IGF-1 levels stayed above baseline for up to 28 days, and no serious adverse reactions were reported. [1]
03 · Numbers in context
What does dosing evidence actually support?
The evidence base is a controlled pharmacology trial in healthy adult volunteers (ages 21 to 61) using ascending subcutaneous doses under direct study supervision, designed to characterize how long GH and IGF-1 stayed elevated after single and multiple dosing rather than to define a maintenance regimen for general use [1]. Reported findings were dose-dependent (with the best tolerability at 30 or 60 micrograms per kilogram in the study), and describe hormone response duration measured in days after dosing, not the overall length of the study itself; the trial did not evaluate a self-directed repeated dosing schedule of the kind discussed outside clinical research.
A study dose is not a personal dose. Population, route, formulation and supervision are part of the result. Online community schedules are not treated here as established clinical protocols.
04 · Safety and limits
What not to overlook
- CJC-1295 with DAC has no FDA-approved indication; the cited trial is a phase 1-type pharmacology study, not an approval trial.
- Sustained elevation of growth hormone and IGF-1 carries theoretical long-term risks that the short trial duration could not assess.
- Research-chemical vials sold under this name have no confirmed identity or purity link to the studied compound.
- The study population was healthy adults under close monitoring using specific studied doses (30 or 60 mcg/kg reported as best tolerated), which differs from unsupervised use.
05 · Product distinctions
Names are not interchangeable
The studied compound was an investigational injectable formulation administered under a clinical pharmacology protocol by the trial sponsor. Reign Peptide sells CJC-1295 with DAC as a lyophilized powder vial for laboratory research reconstitution; this is a distinct, separately sourced product with no established bioequivalence to the trial material.
06 · Handling and storage
Follow validated product instructions
A single water volume, refrigerator temperature or expiry window cannot be assumed for every compound and formulation. Use the exact manufacturer documentation and a validated laboratory procedure. If stability, solvent compatibility or microbiological quality is not documented, those properties remain unverified.
Refrigeration, clear appearance and bacteriostatic water do not make an unverified research product suitable for injection. This guide does not provide a mixing or administration procedure.
The existing concentration calculator checks arithmetic only. It cannot choose a safe dose or establish compatibility, sterility or shelf life.

What remains unresolved?
- What are the safety implications of sustained GH and IGF-1 elevation over periods longer than the 49 days studied?
- How does the drug affinity complex modification affect immunogenicity or long-term receptor sensitivity with repeated dosing?
