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 mg. Right now the cheapest 70 mg option is $2.04/mg, about 97% less per mg than the cheapest 2.5 mg option at $64/mg.
The saving only counts if you can use the vial within its storage window. Check the handling section of the guide before choosing a larger vial. See handling and storage.

What's the cheapest Retatrutide?
The cheapest Retatrutide right now is $2.04/mg at RetaOne Labs for the 70 mg option, after code peptidepub.
How is Retatrutide price per mg calculated?

How often are prices updated?
The catalog is refreshed daily from vendor data sweeps, and the page reflects the current catalog values at build time. When vendor pricing or codes change, the comparison and cheapest-offer answer update from the same source data.
