V·Y·T·A·L — Valine, Tyrosine, Threonine, Alanine, Leucine. A five-residue sequence, and a standard we hold ourselves to: everything we ship is exactly what it says it is.
We source lyophilized compounds from established synthesis labs and hold every incoming batch until independent testing clears it.
Identity and purity are confirmed by third-party laboratories using HPLC and mass spectrometry. Certificates are published, not available on request.
The catalog, the certificates, and checkout are open to browse. No account required to see what we sell or what's in it.
