Four residues and 390 daltons — the smallest compound we test. At this size, net peptide content is not a secondary figure. It is the whole question.

Order this testA tetrapeptide, alanine-glutamate-aspartate-glycine, derived from work on a pineal gland extract conducted in the Soviet Union. Trivially cheap to synthesise by modern standards.
A trifluoroacetate counterion weighs 114 daltons. Against a peptide of 390, that single counterion is nearly a quarter of the combined mass before you account for residual water.
A vial can be entirely genuine, high purity, and still deliver far less peptide than the milligram figure on the label implies. Purity does not detect this. Net peptide content does, and it is reported separately for exactly this reason.
There is little incentive to substitute something else for a peptide this inexpensive. There is considerable incentive to put less of it in the vial, because nobody without an analytical balance and a mass spectrometer can tell.
Epitalon has no approved form, no monograph, and no regulatory specification in Canada. Every claim made about a vial originates with whoever sold it.
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.
