What is CJC-1295 with DAC?
CJC-1295 with DAC is also listed and searched as CJC-1295 DAC, CJC 1295 w/ DAC, CJC-1295 DAC peptide. They all mean the same compound. A name is not a test, which is why the lot record further down counts for more than the wording on a label.
Chemically: molecular formula C165H269N47O46, average mass 3647.2 g/mol (PubChem CID 91971820). Those figures are what the identity test on a certificate is read against.
Tetrasubstituted analogue of human GRF(1-29) bearing a maleimidopropionamide lysine — the Drug Affinity Complex — at the C-terminus.
Agonist at the GHRH receptor on pituitary somatotrophs. The maleimide group reacts covalently with the free thiol at Cys34 of circulating serum albumin, and that conjugation is what extends the half-life from minutes to days.
Characterised in rats, in GHRH knockout mice, and in two randomised placebo-controlled ascending-dose trials in healthy adults. Development did not continue to an approved product.
No approved product and no modern safety record. Sustained rather than pulsatile elevation of growth hormone and IGF-1 is a departure from the physiological pattern whose consequences are not established.
CJC-1295 with DAC for sale: 5mg vials, price per mg
CJC-1295 with DAC is sold in 1 size here, 5mg, from $130.00 a vial. The per-mg column is the honest comparison between sizes; the two tier columns show what ten and twenty vials of one size bill at, because the volume discount is per size and mixed sizes do not combine.
| Size | One vial | Per mg | 10 vials −10% | 20 vials −15% | Availability |
|---|---|---|---|---|---|
| CJC-1295 with DAC 5mg | $130.00 | $26.00 | $1,170.00$23.40/mg | $2,210.00$22.10/mg | Backordered — waitlist |
CJC-1295 with DAC discounts: bulk pricing, Subscribe & Save, and codes
Three things move this price and nothing else does: how many vials of one size are on the order, whether that order repeats, and one code. The fourth column prices each route against the 5mg vial.

The first three stack; the codes do not. A volume discount comes off the line, a subscription cadence comes off that same line from shipment 2, and one code comes off what is left. One code per order, never two. A subscription runs a minimum of two shipments and can be cancelled once the second has shipped, and the first shipment always bills at today's eligible price with no cadence discount on it. The lowest this record ever bills is $20.77 per mg: twenty 5mg vials on a monthly subscription, from shipment 2 onward.

Where to get CJC-1295 with DAC, and how to buy CJC-1295 with DAC online
You can buy CJC-1295 with DAC online here with guest checkout; verified in-stock orders placed before 12 PM Pacific are dispatched the same day.
Run these on us too. A supplier who cannot pass them is asking you to take their word for it, and their word is the one thing a certificate exists to replace.
- Check the certificate on the lab’s own site, not ours.
- See whether it was written for the seller.
- Match the lot number on the paper to the one on the vial.
- Look for a method and a date next to every number.
- Make sure identity was tested, not assumed.
Each of those is worked through, with what a failed check actually looks like, on verifying a certificate.
CJC-1295 with DAC guides and documentation
Written to answer the questions that come up around CJC-1295 with DAC specifically — what its paperwork should show, how it is handled, and how to judge a supplier selling it.
The full library, grouped by what you came to answer, is in the laboratory guides.
The CJC-1295 with DAC certificate: lot, purity, identity, and how to verify it
A certificate answers identity, purity and net content as three separate questions, each with the method that produced it and the date it was run — how to read one covers what each field does and does not cover. For CJC-1295 with DAC that means a mass spectrum landing on 3,647.2 g/mol for C165H269N47O46, the figure published against PubChem CID 91971820.
The certificate below belongs to one lot, and its number matches the one printed on the vial you receive. A real report for a different batch is still the wrong report.

Where the FDA stands on CJC-1295 with DAC
The FDA has not approved this compound for anything, and nothing in this catalogue is a medicine. Where a compound stands legally depends on what it is, what form it is in, what it is being used for and which country you are in, and it changes over time, so the status shown here carries the date it was last checked.
Status verified 2026-08-25. Regulatory positions move; check the primary source before relying on any summary, including this one.
It is sold here as laboratory material under the research-use restriction that closes this page, which is not an approval, and not a statement that the compound is safe, effective or right for any purpose.
CJC-1295 with DAC research: what the published studies examine
Status: No FDA-approved application. This compound is sold as laboratory material. Where research on it has been published, it sits at the animal, cell or early-human stage, and this record does not summarise what it found. A supplier is not a neutral judge of evidence about its own catalogue.
This is the molecule the published CJC-1295 literature actually describes, and it is worth being explicit that it is a different product from the no-DAC version also sold on this catalogue. CJC-1295 is a tetrasubstituted form of hGRF(1-29) with an added N-epsilon-3-maleimidopropionamide derivative of lysine at the C-terminus. The four substitutions confer resistance to dipeptidyl peptidase-4; the maleimide is the part that matters most, reacting covalently with the free thiol at Cys34 of serum albumin so the peptide circulates bound to a carrier protein with a multi-day residence.
It binds the GHRH receptor on pituitary somatotrophs, acting upstream of growth hormone rather than supplying it.
| Reported observation | Model | Source |
|---|---|---|
| Identified as the best of three maleimido hGRF(1-29) derivatives, characterised as tetrasubstituted hGRF(1-29) with an added maleimidopropionamide lysine at the C terminus. All three conjugates showed enhanced in vitro stability against dipeptidylpeptidase-IV. Western blot of plasma from injected rats showed the compound on the band corresponding to serum albumin from 15 minutes and remaining beyond 24 hours, with the compound detectable past 72 hours. | in vitro DPP-IV stability, cultured rat anterior pituitary cells, rat pharmacokinetics | Jette and colleagues, Human growth hormone-releasing factor (hGRF)1-29-albumin bioconjugates activate the GRF receptor on the anterior pituitary in rats: identification of CJC-1295 as a long-lasting GRF analog, Endocrinology (2005)Authored at ConjuChem, the developing company. |
| In two randomised placebo-controlled ascending-dose trials, single subcutaneous injections produced dose-dependent increases in mean plasma growth hormone of two- to ten-fold sustained for six days or more, and IGF-1 increases of 1.5- to 3-fold for nine to eleven days, with an estimated half-life of 5.8 to 8.1 days. After multiple doses IGF-1 remained above baseline for up to 28 days. No serious adverse reactions were reported. | randomised, placebo-controlled, double-blind ascending-dose trials in healthy adults aged 21 to 61 | Teichman and colleagues, Prolonged stimulation of growth hormone (GH) and insulin-like growth factor I secretion by CJC-1295, a long-acting analog of GH-releasing hormone, Journal of Clinical Endocrinology and Metabolism (2005) |
| In GHRH knockout mice, once-daily administration maintained normal body weight and length; every 48 or 72 hours produced partial but incomplete normalisation. Total pituitary RNA and growth hormone mRNA rose and immunohistochemistry supported proliferation of somatotroph cells, indicating the effect is not simply release of stored hormone. | GHRH knockout mice, five weeks from one week of age | Alba and colleagues, Once-daily administration of CJC-1295, a long-acting growth hormone-releasing hormone (GHRH) analog, normalizes growth in the GHRH knockout mouse, American Journal of Physiology: Endocrinology and Metabolism (2006)Johns Hopkins, independent of the originating company. |
Open questions. The evidence base here is genuinely better than for most of this catalogue: a defined mechanism, an independent knockout-mouse study, and two randomised human trials with pharmacokinetics. Three things still need saying. Development stopped, so there is no approved product, no pharmacopoeial standard and no long-term safety record — and a compound that reached randomised human trials and went no further has been tested more than most things sold here without producing a licensed medicine.
Sustained elevation of growth hormone and IGF-1 over days to weeks is a real departure from the pulsatile physiological pattern, and whether that is desirable is an open question rather than a selling point. And the somatotroph proliferation reported in knockout mice is a structural change in the pituitary, not merely a secretory one.
Each row above describes an observation in the stated model. None of it describes what CJC-1295 (with DAC) would do in a person or an animal outside that model, and none of it is a recommendation to use it for anything.
