The Tool · Free, no account

The per-mg calculator that already knows the vendors.

We tracked down the prices so you don’t have to start from scratch. Open it, see what 18 vetted vendors charge per milligram right now, then add your own sources alongside. Your research, your numbers, one honest comparison.

Starts loaded.

PPL’s vetted vendor list is already in there — current prices, per-mg math done. You’re not building a spreadsheet from zero.

Add what we don’t have.

Found a vendor we haven’t scored yet? Add a row. Your compounding pharmacy, your clinic’s supplier, whatever you’re actually comparing. It lives next to ours.

Just the math.

No rankings paid for by vendors. No affiliate pressure. The number that matters is price per milligram, and this tool does that calculation out loud, every time.

Open it and start comparing.

No account required. We don’t sell the list. If we ever use affiliate codes, it’s disclosed on the page.
