AOD-9604 carries two cysteines that are supposed to be joined. Whether they actually are is a two-dalton question, and two daltons is the difference between the compound and something that merely contains its parts.

Order this testThe 176–191 fragment of human growth hormone with a tyrosine added at the N-terminus. The two cysteine residues form a disulfide bridge that closes a loop within the molecule.
Closing a disulfide bond removes two hydrogen atoms. Correctly folded AOD-9604 is therefore two daltons lighter than the same chain with its cysteines still free.
Two daltons in 1815 is roughly one part in a thousand. It is also the difference between the intended three-dimensional structure and a floppy chain with the right composition.
AOD-9604 is sixteen residues of a 191-residue hormone. It is sometimes marketed with language borrowed from growth hormone itself, which is a claim about a different molecule roughly twelve times the size.
As with TB-500, suppliers do not always use identical fragment boundaries, and the added N-terminal tyrosine is sometimes omitted. Each variation shifts the mass in a way that identification by name cannot capture.

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.
