Where to buy CJC-1295 No DAC: reading the listing and the lot record

What is CJC-1295 no DAC, and what is it not?

"CJC-1295 no DAC" is a market name for a molecule the literature calls Mod GRF(1-29) or tetrasubstituted GHRH(1-29): the first 29 residues of growth-hormone-releasing hormone with four changes, D-alanine at position 2, glutamine at 8, alanine at 15 and leucine at 27, and an amidated C-terminus. The name is a hand-me-down. CJC-1295 proper, described in the papers cited at the foot of this page, is that same peptide with a "drug affinity complex" attached, a lysine carrying a maleimidopropionyl group that binds to albumin. Take the complex off and what remains is Mod GRF(1-29). The words "no DAC" say what the vial does not contain; "Mod GRF(1-29)" says what it does.

The masses settle the naming. Mod GRF(1-29) has the formula C152H252N44O42 and an average mass of 3,367.9 Da. CJC-1295 with DAC is 3,647.3 Da, about 280 Da heavier for the linker. And sermorelin, the unmodified GHRH(1-29) amide, is 3,357.9 Da, ten daltons lighter than Mod GRF because of the four substitutions. Three closely related peptides, three masses, and listings that use all three names for whichever one is in stock. A certificate that prints the observed mass tells you which; a certificate that prints "CJC-1295" and a percentage does not.

The substitutions were chosen for stability: glutamine at 8 replaces an asparagine that deamidates, alanine at 15 replaces a glycine that lets the chain be cleaved, leucine at 27 replaces a methionine that oxidizes, and D-alanine at 2 resists the enzyme that clips the native hormone. That is chemistry a buyer can use, because it means the certificate for a real Mod GRF lot should not show the oxidation and deamidation peaks that a sermorelin lot often does. The research record is thin and this page describes the material, not any use.

PubChem has no record for CJC-1295 no DAC under any of its names as of September 5, 2026, so the reference figures come from the developer literature: molecular formula C152H252N44O42, average mass 3367.9 Da. Certificates commonly print 3367.9 Da average; check the value against the sequence on the certificate, not against CJC-1295 with DAC (3647.3 Da).

In plain terms: A man-made 29-building-block copy of GHRH, also sold under the name Mod GRF(1-29). No approved product. The with-DAC and no-DAC versions are chemically different molecules with different handling needs and must not be treated as the same thing. This record is about the no-DAC form.

CJC-1295 no DAC for sale: what do the sizes cost per mg?

LabFirst lists CJC-1295 no DAC in 2 sizes (5mg, 10mg) from $34 to $85, priced per vial with the per-mg figure beside it so sizes can be compared without arithmetic. Per mg, the 5mg vial is the cheapest today at $6.80 and the 10mg the dearest at $8.50, which is the reverse of the usual shape; the table below is the arithmetic, and the per-mg column, not the vial price, is the one to compare.

The volume tiers are per size, not per basket: ten vials of one size take 10% off that line and twenty take 15%, and mixed sizes do not combine. Ground Advantage shipping is a flat $15 on orders under $200 and free from $200, within the United States only, with same-day dispatch on orders placed before 12 PM Pacific on a business day. The cost per mg tool runs the same comparison across any two listings, ours or anyone else's.

A 29-residue synthesis with one D-amino acid is mid-priced work, more than a tripeptide, far less than a lipidated 39-mer, and Mod GRF sits in the middle of the catalog per milligram. The size table on this page has an odd shape today: the 5 mg vial is cheaper per milligram than the 10 mg vial, the reverse of the usual pattern, which reflects the two lots' costs rather than any rule, and the per-milligram column rather than the vial price is what to compare. A laboratory qualifying a lot buys one 5 mg vial and checks it against its certificate before anything larger.

The price signal to read across sellers is the gap between the three names. Sermorelin, Mod GRF(1-29) and CJC-1295 with DAC cost different amounts to make, the DAC version most because of the linker chemistry. A seller pricing all three the same per milligram is selling one peptide under three names, and the certificate's observed mass will say which one. The only discounts on this page are the volume tiers, per size and the same every month.

What should a CJC-1295 no DAC certificate show?

Three tests answer three different questions, and a certificate of analysis for CJC-1295 no DAC is only complete when it carries all three for the exact lot on the vial. Identity is settled by mass spectrometry against the published mass for CJC-1295 no DAC (3367.9 Da average). The certificate should print the theoretical value beside the observed one; a tick in a box is not an identity result.

Purity is a separate question, answered by HPLC: how much of what came off the column was the compound. The figure is only interpretable with its method beside it (column, gradient, detection wavelength) and a date, which is what ICH Q2(R2) means when it asks that an analytical procedure be shown fit for its purpose. A percentage with no method and no date is a number somebody typed, and a certificate that carries every test but for a different lot number than the vial is the most common failure of all and the easiest to catch. Net content is the third test and the one most often missing: the milligrams of CJC-1295 no DAC actually in the vial, measured, against the size printed on the label.

Identity is the observed mass against 3,367.9 Da average (the monoisotopic value is about 3,365.9 Da), and the certificate should say which it reports. The electrospray spectrum shows charge states from roughly 3+ to 6+ (m/z 1,124, 843, 675 and so on) that deconvolute to one value. Two neighbours must be excluded: 3,357.9 Da is sermorelin, ten daltons away and only distinguishable by a laboratory that reports to the dalton; 3,647.3 Da is CJC-1295 with DAC, the linker still on. A rounded "3.4 kDa" on a certificate could be any of the three, and a listing that gives no mass at all is asking you to trust its word on which peptide it bought.

Purity by HPLC on a 29-residue peptide is a resolution problem in the usual places: deletion sequences, a leftover protecting group, and oxidized or deamidated forms that a properly substituted Mod GRF should lack. The chromatogram, with its column, gradient and wavelength, is the evidence. Net content is the third line and here it is the one that pays: the peptide is often supplied as trifluoroacetate from purification, which is heavier than acetate and drags the peptide content of a labeled milligram down. A laboratory that reports net peptide content by quantitative HPLC or amino acid analysis has told you what the milligrams are made of.

Where to buy CJC-1295 no DAC: which five checks come first?

Every seller of cjc-1295 no dac says "third-party tested". The phrase costs nothing. These five checks take about four minutes per listing and separate a tested lot from a tested-sounding one.

1. The lot on the vial is the lot on the certificate. Read the printed lot number, then open the certificate and match it. A certificate for "CJC-1295 no DAC" with no lot, or a lot that does not match, describes some other vial.
2. The laboratory is named and has its own lookup. The report should come from a laboratory the seller does not own, with a search code you can enter on the laboratory's own site. LabFirst lots are tested by an independent laboratory and the laboratory's report is published for each lot; anything that exists only as the seller's own summary has not been verified.
3. The theoretical mass is printed, and it is the right one. For CJC-1295 no DAC the figure should match the published formula C152H252N44O42.
4. Purity has a method and a date. An HPLC percentage should name the method and the run date. A figure that reads "99%+" with neither, or one date reused across every product a seller lists, is decoration.
5. Net content is stated in milligrams. The label size is a claim; the certificate's net content is the measurement. If the certificate has no net content line, the purity figure describes the powder, not the vial, and the price per mg you calculated is fiction.

Which red flags show up on CJC-1295 no DAC listings?

The ways listings for this compound go wrong:

• "CJC-1295" with no mention of DAC and no mass. The name properly belongs to the albumin-binding version at 3,647 Da; a vial at 3,368 Da is Mod GRF(1-29) and should be sold as that.
• Sermorelin sold as CJC-1295 no DAC, or the reverse. They are ten daltons apart (3,357.9 against 3,367.9 Da) and only a certificate that reports to the dalton tells them apart.
• "99% purity" from a chromatogram with no method or date. Deletion sequences and a leftover protecting group run near the main peak; a number without the trace cannot show they were resolved.
• A 10 mg label with no counter-ion and no net content. Trifluoroacetate salts carry less peptide per milligram of powder than acetate salts; without the content line the milligrams are unknown.

How do I verify a LabFirst CJC-1295 no DAC lot?

The CJC-1295 no DAC sizes in stock today carry lot LF-07A-2609. Lot LF-07A-2609 is at the laboratory for identity, purity and net content. Until the report is attached the product page says "pending verification" against that lot and makes no purity claim; the price stands and the report goes live the day it arrives, on the page and at /coa/.

Verification runs through the laboratory, not through us. Open the certificate index, find the lot, and read the laboratory's report; it is the laboratory's own document, not ours, and the laboratory will confirm it against its records.

The product page reads the live stock feed on load (stock, lot and certificate state for every size), so what you see when you order is what ships. The lot is printed on the label and encoded in the QR patch on its right-hand side; scanning it opens that lot's record.

How should CJC-1295 no DAC be stored, and how does it ship?

Mod GRF(1-29) was designed to be the stable member of its family, and lyophilized at 2 to 8 C out of light it is: no methionine to oxidize, the deamidation-prone asparagine replaced, the labile glycine gone. That does not make it immortal. It is a 29-residue peptide with a tryptophan, so light exposure matters, and it is supplied as a salt that takes on water from humid air, so the sealed cake is opened once, for its purpose, and never re-sealed for storage.

Orders ship within the United States, Ground Advantage at a flat $15 under $200 and free above it, same day when placed before 12 PM Pacific on a business day, and the shipping page states the cutoff, the carriers and what is and is not promised.

The record a laboratory keeps on arrival is what makes the certificate usable later, and it is short:

• the lot number as printed on the vial, and the certificate's accession or search code beside it;
• the date received and the condition of the seal;
• the storage location and temperature it went into;
• the number of vials, and later the date each one was opened and by whom.

A CJC-1295 no DAC vial with that record behind it can be traced from the bench to the laboratory report in one step; without it, the certificate is a document about a vial that can no longer be identified.

What is the regulatory status of CJC-1295 no DAC?

No approved medicine contains Mod GRF(1-29) or CJC-1295, and no USP or Ph. Eur. monograph defines an acceptable lot of either. In September 2023 the FDA placed "CJC-1295" in Category 2 of its interim list of bulk drug substances nominated for compounding under section 503A, the category for substances it has identified as raising significant safety risks, without distinguishing the DAC and no-DAC forms; licensed pharmacies may not compound with it. That listing is about pharmacies, not laboratory material. It is quoted because "pharmaceutical grade CJC-1295" appears in listings, and a substance on Category 2 with no monograph is not a grade of anything.

FOR LABORATORY AND IN-VITRO RESEARCH USE ONLY. NOT FOR HUMAN OR ANIMAL CONSUMPTION. LabFirst sells CJC-1295 no DAC to laboratories and researchers as material for in-vitro work, gives no guidance on use, and ships only against that understanding. Nothing on this page or on the product page describes preparing or administering anything.

Bottom line

CJC-1295 no DAC is Mod GRF(1-29), 3,367.9 Da, and it shares its market with two near neighbors: sermorelin at 3,357.9 Da and CJC-1295 with DAC at 3,647.3 Da. Only the observed mass on a certificate says which one is in the vial. Buy against a certificate for the printed lot, with purity by HPLC beside its method and date and net content in milligrams. Today the 5mg vial is the cheapest per mg at LabFirst.
