How reconstitution works

Add your calculated amount of bacteriostatic water (BAC water) to the lyophilized peptide vial by gently squirting it against the side of the vial — never directly on the powder. Swirl gently until dissolved. The resulting concentration determines how much you draw per dose. Store reconstituted peptides in the refrigerator and use within 4–6 weeks.

Now track your doses

You've reconstituted — now log every injection, track your cycle progress, and never second-guess if you already dosed today.
