What B12 costs right now

Across the 2 B12 vial sizes in stock for US delivery, the average price per vial runs $5.00, and individual in-stock offers span $5.00 to $5.00 per vial. That spread is the honest one: a domestic lane normally prices above an international one for the same vial.

The lowest cost per milligram sits at the 10 mg vial: $0.50 per mg, off an average of $5.00 per vial across 1 in-stock offer. Larger vials almost always lower the per-mg cost, so compare $/mg before you compare sticker price.

Deepest supply on any single size is 1 distinct source with stock in the US lane, seen on a pricelist within the last 30 days. No domestic US warehouse lane is currently stocking it.

How this index is calculated

Deliberately vendor-blind. Every price is an aggregate across the in-stock suppliers we track — no vendor names, no per-vendor breakdowns. The hero price is the mean per vial across every in-stock offer in the standard kit; kits vary in size, so per-kit totals aren't comparable and bulk/trial tiers are held out of the mean.

The market range shows the honest spread — domestic lanes typically price above international ones. Blends and oils don't show a $/mg (two compounds, or a per-ml concentration). Prices are for the product only and exclude shipping; your exact kit, lane, and delivered total are quoted at order time. Research use only.

Source counts. Each card's source count is the number of distinct suppliers with that product in stock for your selected delivery lane — counted across the full supplier pricelists we track, not just the ones behind the displayed average. A supplier only counts if its pricelist passed validation and the offer was seen within the last 30 days, so a frozen or quarantined listing never inflates the number. For the few products we can't match in the supply feed, the count falls back to the suppliers currently priced in the catalog.

Want to know which supplier sits behind each price and how its batches tested? That's the vendor trust records and the COA database — third-party lab certificates, graded independently. Go Pro to unlock the source behind every row.

B12 pricing, answered

How much does B12 cost?

For US delivery, the average in-stock price runs $5.00 per vial, built from 2 live offers across 2 vial sizes. Individual offers run $5.00 to $5.00 per vial. Prices are for the product only and exclude shipping.

What is a good price per mg for B12?

The median across the mg-dosed sizes in stock is $0.50 per mg, and the cheapest size on that basis is the 10 mg vial at $0.50 per mg. Anything meaningfully below the bottom of the range on this page usually means an international lane with longer shipping rather than a better deal.

Is B12 in stock?

Yes, as of the last refresh (2026-08-01). Every row on this page is a live in-stock offer in the US delivery lane, and the deepest size carries 1 distinct supplier seen on a pricelist within the last 30 days. A compound with nothing in stock does not get a page here at all.

Why don't you show which vendor has each B12 price?

This page is deliberately vendor-blind so it stays an honest market reference, not an ad. The supplier behind each row, its trust record, and the batch lab certificates are unlocked with Pro.
