Sermorelin and the compound sold as CJC-1295 without DAC are separated by about ten daltons in more than three thousand. This is the closest pair we test, and the hardest to call without weighing the molecule properly.

Order this testThe first 29 residues of growth hormone-releasing hormone, unmodified. It is the parent structure from which several of the more heavily marketed compounds in this category are derived.
Modified GRF(1-29) — sold as CJC-1295 without DAC — is sermorelin with four amino acid substitutions designed to resist degradation. Those four changes shift the mass by roughly ten daltons out of 3358.
That is three parts in a thousand. Nothing about the two compounds looks different, they behave almost identically on a column, and the price gap between them is real.
Sermorelin is a fragment; tesamorelin is the full 44-residue chain with an added acyl group. They are nearly 1800 daltons apart and routinely marketed as interchangeable.
3357.9 vs 3367.9
Sermorelin against modified GRF(1-29) — about 10 daltons apart, roughly 0.3%
Three parts in a thousand is the analytical equivalent of telling apart two people of the same height by weighing them to the gram. It is entirely doable, and only with an instrument that measures mass rather than timing. How that works.
One unopened vial. Detailed posting instructions arrive with your order confirmation, immediately after you pay.
No. Lyophilised peptides travel safely at room temperature, which is how nearly all samples reach us.
An independent Ontario laboratory. Every certificate we issue names the facility that ran it — we are a testing service, not a laboratory, and we would rather say so than let you find out from the report.
You get the result. We do not soften findings, and we do not charge differently depending on what the analysis shows.
Yes. Every certificate carries an identifier that anyone can check against our records, including the vendor you bought from.
