Five calculators, no sign-up

The same five that ship inside PepStock, free to use here. They convert a number you already have — onto a syringe, onto a calendar, or into what it costs. None of them recommends a dose.

They fill themselves in from your own stock

On the website you type the numbers. In PepStock you pick a product and the strength, the price you paid and the water you added are already there — so the vial-cost answer is your real cost, not an estimate, and a blend loads its composition from the compound library.

Both sides get them — yours and your resellers'
