What you will notice

First mix: the cake lifts and clears in seconds, and the first injection stings less than you expected. First week: the routine stops needing thought, and your units read the same every day. Weeks two to four: the vial is still clear, still drawing cleanly, and the stopper still seals behind the needle. Longer: you settle on one water volume for each peptide you run, the arithmetic becomes automatic, and the only thing you still check is clarity before every draw.
