Where to buy CJC-1295 No DAC: sizes, price per mg and how to verify the lot

What "cjc-1295 no dac" names, and what it does 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 oxidises, 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: sizes and price 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. 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 catalogue 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.

The certificate a CJC-1295 (no DAC) lot must carry

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 oxidised 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 labelled 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): five checks before you order from anyone

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 Freedom Diagnostics and looked up by accession number; anything that can only be verified on the seller's own page 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.

How listings for CJC-1295 (no DAC) specifically mislead:

• "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 to verify a LabFirst CJC-1295 (no DAC) lot

The CJC-1295 (no DAC) sizes in stock today carry lot LF-2608-07. Lot LF-2608-07 is at Freedom Diagnostics on accession FD-2026-05716 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, at /coa/, and inside the receipt and packing slip for every order of that lot.

Verification runs through the laboratory, not through us. Open the certificate index, find the lot, and use the accession number on the Freedom Diagnostics lookup page; the report you see there is the laboratory's copy, not ours. Each lot also carries a Finnrick verify link, and every receipt and packing slip states that a customer may submit a sealed vial to Finnrick's free testing programme with the order as proof of purchase, so the brand's public record is built from vials we did not choose.

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.

Storage and shipping for CJC-1295 (no DAC)

Mod GRF(1-29) was designed to be the stable member of its family, and lyophilised at 2 to 8 C out of light it is: no methionine to oxidise, 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 of a solution 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. In solution the record belongs to the laboratory: solvent, concentration, date, temperature, and its own stability check, since no label can stand in for it.

Orders ship within the United States, 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.

Regulatory status, and what this page is not

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.
