Cost Per Dose Calculator
A vial price states what the vial costs. This states what a dose costs — at every vendor Prof. Peptide tracks, after its discount code, from whole doses out of real vials. Enter the dose to price; this page does not suggest one. For capsules, the Capsules option prices a bottle from its price, capsule count and mg per capsule.
Choose a compound and enter the dose to price. This tool does not suggest a dose and has no default: the figures below appear only once one is entered.
How this works
- Whole doses only. A vial yields as many complete doses as it holds; any remainder is reported beside the row rather than counted as if it could be injected.
- Ranked after the code. The figures apply Prof. Peptide’s discount for each vendor. The price pages compare list price to list price instead, which answers a different question and can rank vendors differently.
- Every price is dated. Prices are read from each vendor’s own store on the date shown. Nothing here is live, and a stale price is labelled with its age rather than quietly presented as current.
- Where a better public offer exists, it is named. A vendor whose own public discount is larger than Prof. Peptide’s still appears, with that fact stated in its row. Reporting what is actually paid matters more than flattering the code.
Frequently asked questions
How is cost per dose calculated?
The vial's price with Prof. Peptide's discount applied, divided by the number of whole doses the vial holds. A 10 mg vial at a 3 mg dose holds 3 whole doses and leaves 1 mg, so the cost per dose is the vial price divided by 3 — not the price of 3 mg. Dividing by milligrams instead would understate the cost, because the remainder cannot be bought or used separately.
Why does one vendor show only one vial size?
The table shows each vendor's cheapest cost per dose and names the vial it assumes. Where a vendor lists several sizes, the row links to all of them — the spread inside a single vendor can be very large, so the vial matters as much as the vendor.

This page takes a compound and a dose and returns what one dose costs at each vendor Prof. Peptide tracks prices for, after its discount code, using whole doses from real vial sizes and prices. Each row shows the date that vendor's price was read.
How current are these prices?
Every row carries the date that vendor's price was read from its own store. A price read more than 30 days ago is shown with its age rather than hidden, so its age can be weighed. A vendor whose price or read-date is missing does not appear at all — a missing price is never treated as zero.
Why do some compounds not appear?
A compound appears only when at least 3 tracked vendors have it in stock — the same threshold the price pages use. Below that there is no comparison to make: with two vendors a single unusual listing sets the whole picture.
