Vitamin B12 vendor prices

Compare research-peptide vendor listings, package sizes, prices, and linked laboratory evidence.

"from" means the vendor lists a price range for that item (bundle/quantity variants) and only the low end is shown here — click through to the vendor for exact pricing. $/mg is only calculated when the vendor states an exact size for that price. Not medical advice. All listed products are sold by vendors as research chemicals, not for human consumption.
