CJC-1295, tested by an independent U.S. lab.

Two compounds share the name CJC-1295: one carries an extra chemical group called DAC and one does not. They are priced differently, they behave differently, and they weigh differently. At the point of sale the label is the only thing separating them, which also makes the label the easiest thing to get wrong, deliberately or otherwise. We identify which version is in your vial by its mass and print that on the certificate. Identity, quantity, and purity are included in the base test. Endotoxin testing, sterility testing, and heavy metals testing are available as optional add-ons.

How a sample becomes
a certificate.

Every CJC-1295 sample moves through the same five steps. No shortcuts for rush orders. No unnamed hands in the middle.

Intake.

Your sample arrives. We photograph it, weigh it, log every detail, and assign a tracking number that follows it onto every page.

Prep.

A named analyst prepares the run: dissolutions, dilutions, internal standards. Their initials go in the log.

Run.

HPLC-UV for purity, LC-MS for identity, and quantitative analysis for the amount present, with system-suitability standards bracketing your sample on either side.

Review.

A second analyst reviews the chromatogram independently. Nothing ships with one set of eyes on it.

Sign.

The COA is digitally signed, hashed, and published. Anyone with the link can verify the signature against the raw data.

What we look for

What we look for in CJC-1295

DAC or no DAC.

The modification adds 279.3 daltons, far beyond any measurement uncertainty. We report which version your sample is, whatever the vial says.

The peptide backbone.

Strictly, what the market calls CJC-1295 without DAC is Mod GRF 1-29; the original compound named CJC-1295 is the albumin-binding DAC version. Intact mass confirms the backbone before the modification is even considered.

Purity against the right target.

Percent area by HPLC-UV, measured against the version we identified. Grading a no-DAC sample against DAC expectations produces a meaningless number.

What you receive

Paper you can stake a reputation on.

01

A signed Certificate of Analysis

Identity, quantity, and purity on one document, signed by the director, not a template stamp.

02

Method-level transparency

Column, wavelength, ionization mode, and acceptance criteria are stated, not implied.

03

Public verification

Each COA carries a hash and signature anyone can check at our verify endpoint, on or off our site.

Frequently asked

CJC-1295 testing, answered.

Does ECA test CJC-1295 samples?+
Yes, both versions. You do not need to know which one you have when you submit it. We identify the version by intact mass and report it with the measured quantity and HPLC-UV purity result.
Is CJC-1295 testing performed in the United States?+
Yes. All analysis is performed in-house at our laboratory in Elyria, Ohio. We are an independent U.S. lab. We don't outsource testing or ship samples overseas, and every result is produced and signed by our own analysts.
What does the CJC-1295 Certificate of Analysis include?+
A completed CJC-1295 COA documents identity by intact-mass LC-MS, the measured quantity, HPLC-UV purity as percent area, the method parameters used, and the analyst and director who signed off. It is digitally signed and independently verifiable.
How long does CJC-1295 testing take?+
Typical turnaround is 24-48 hours from the day your sample is received at the lab. You'll get shipping instructions, a packing slip, and labels after checkout.
What methods are used for CJC-1295 identity, quantity, and purity?+
Identity is confirmed by LC-MS intact-mass analysis. Quantity is measured and reported separately from percent-area purity. Purity is measured by reversed-phase HPLC-UV and reported as percent area.
I ordered CJC-1295 with DAC. How do I know that is what arrived?+
Mass. The DAC modification is heavy enough that its presence or absence is unmistakable on an intact-mass measurement. This is one of the most common mismatches we see, and it is invisible on a purity-only certificate, because a no-DAC sample can be perfectly pure and still be the wrong product.
Is this medical or dosing advice?+
No. ECA provides analytical testing for research compounds only. We do not provide medical advice, dosing guidance, treatment claims, or clinical evaluation of any kind.
