Which size should I buy?
Bigger vials cost less per mg. Right now the cheapest 10 mg option is $3.82/mg, about 52% less per mg than the cheapest 5 mg option at $7.92/mg.
The saving only counts if you can use the vial within its storage window. This peptide's guide lists a reconstituted use-within window of up to 28 days only when the product-specific instructions support that window. See handling and storage.
Smaller vials cost more per mg but waste less if a vial sits open past its window. Filter to 5 mg and Filter to 10 mg.
