Big vial worries?

40-50mg vials work over 2-3 months if stored correctly. Core protocol: reconstitute in BAC water, refrigerate immediately, date the vial. Some people split into smaller aliquots at reconstitution to limit draws from the main vial - each draw is a contamination risk.
 
A 50mg vial at 2.5mg weekly is about 5 months of supply - lyophilized powder holds for 12+ months unopened. The actual limit is post-mix shelf life (28-30 days), so reconstituting small batches rather than the whole vial is the right approach.
