Cheapest SS-31 price FAQ
What's the cheapest SS-31?
The cheapest SS-31 right now is $2.38/mg at Double R Labs for the 50 mg option, after code PEPTIDEPUB.
How is SS-31 price per mg calculated?
PeptidePub normalizes each vial by dividing the effective checkout price by the listed size in mg. That lets different vial sizes sit in one cheapest-first comparison.
Are discount codes included in these prices?
Yes. When a vendor has a confirmed code percent in the catalog, PeptidePub applies that discount before calculating effective price and effective price per unit. Codes without a confirmed percent are shown, but they are not used to lower the calculated price.
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.
