Free peptide supply calculators and readers
The calculators and readers that do the work people get wrong most. All six are free and run in your browser. The two calculators and “Which one do I need?” remember your last entry on this device; the finder, the comparison and the translator keep their settings in the page address, so a bookmark or a shared link opens the same view. None of them gives dosing advice; they do sums on numbers you already have, or read specifications the product records already carry.
Which one do I need?
Tap what you are doing (a vial, a pen, travel, storage, disposal) and get the short list of supplies you need, what is worth adding and what to skip.It lists supplies only; it does not choose a peptide or an amount.Reconstitution calculator
How much bac water to add, and where an amount you have already chosen lands on a U-100 syringe. Covers the 0.3, 0.5, 1 mL and half-unit barrels.It does not tell you what the amount should be.Temperature-loss calculator
A vial left out overnight or a parcel in a hot van: enter the state, the temperature and the time, and get a rough estimate of potency left.It cannot measure your vial or say whether a product is fit to use.Amazon listing translator
Paste a listing title like “31G 5/16 inch 0.3cc U-100 Luer Lock 100 Pack” and every number comes back explained, then opens the Finder with those specs set.It reads only what the title says, not whether the seller is honest.Compare products
Two to four products from one category side by side, every recorded specification in its own row, differences marked.Recorded specifications only: no live prices, no review scores.Product Finder
Filter one category by the specifications that change the answer: gauge, barrel size, smallest marking, hours cold.It cannot tell you which category you need; start from your situation for that.Coming next: a nasal-spray press counter. Ask for a tool on the about page and it goes on the list.
