As a former chemist, I have a journal tracking most things. However, after reading this thread, I realize that I could have tracked more
What I track:
For inventory: vials purchased, purchase date, supplier, COAs, price, vials remaining
For stockpile/future purchase: total quantity in hand, target quantity, next purchase quantity, entire/due quantity
Reconstitution: supplies inventory, reconstitution calculations, label information
Pinning: date, dosage(mg), units, peptide
General notes: price tracking, weight tracking, protocol notes, and other random thoughts.
What I am missing, I now realize, is tying pins back to lot numbers and injection site information. Time to tweak my journal.
