See our methodology. Best value is the lowest $/mg among vendors with verifiable published testing; Best tested is the vendor passing the most of our 7 testing checks.
Which size should I buy?
Bigger vials cost less per mL. Right now the cheapest 30 mL option is $0.47/mL, about 69% less per mL than the cheapest 3 mL option at $1.50/mL.
