The fastest way to report an arithmetic error, a broken link, or a mistake in the content.

What to write about
The most useful emails are the ones that help make the site more accurate. If a calculation looks wrong, include the numbers you entered — vial amount, water amount, dose, and unit — and the result you expected, so the arithmetic can be checked directly. If a page has a broken link, a typo, or a number that disagrees with another page, include the page address and the sentence involved. If a search term or compound is missing from the site and you think it belongs in the calculator pages, say which one and why people search for it. Every report like that is read, and confirmed errors are corrected.
What this inbox cannot answer
This inbox cannot answer health questions. It cannot say what dose anyone should use, whether a compound is appropriate for anyone, or what a result means for a person’s health. Those are questions for a licensed healthcare professional, and emails asking them will be answered with a referral to one rather than an answer. The same applies to questions about buying peptides or about vendors: this site does not sell anything, does not recommend vendors, and cannot help with purchases. The boundary is stated on every page of the site — pure math only, not medical advice — and the inbox follows the same rule.
Response time
This is a small, independently run site, so replies are not instant. Error reports are prioritised over general questions, and a correction, once confirmed, is usually published with the next site update. If you do not hear back within a reasonable time, the most likely reason is that the message went to the wrong address — double-check the spelling of the email above before writing again.
Before you write
Most questions about the calculator are already answered on the site itself. The homepage explains the four formulas and works through the opening example step by step. The reconstitution page explains what the water amount does. The dosage chart page has worked tables for common example combinations. The BAC water guide answers the most-asked question in the niche — how much water for a given vial — with a formula and a table. And the frequently asked questions at the bottom of each calculator page cover the unit conversions and the syringe warnings. If your question is about the math, the answer is very likely already there.
How to hand-check any result
You do not need to take the calculator’s word for it — every result on this site can be checked by hand with four short formulas. Concentration in mg/mL is the vial amount divided by the water: 5 mg in 2 mL is 2.5 mg/mL. Multiply by 1,000 for mcg/mL: 2,500 mcg/mL. Divide by 100 for mcg per unit: 25 mcg per unit. Volume per dose is the dose divided by the concentration: 500 mcg divided by 2,500 mcg/mL is 0.2 mL. Units are the volume times 100: 0.2 mL is 20 units. Doses per vial are the vial amount divided by the dose: 5,000 mcg divided by 500 mcg is 10 doses. If you email about a result that looks wrong, include these five numbers — vial, water, dose, and the result you got — and the arithmetic can be re-checked directly from your message.
What happens after you report an error
Confirmed arithmetic errors are corrected in the calculator code and in every page that quotes the wrong number, then the site is rebuilt and redeployed. Content errors — a wrong search volume, a mistyped example, a broken link — are fixed the same way. You will usually get a short reply confirming the fix. Suggestions for new compound pages are kept in a list for the next phase of the site, which will add tirzepatide, semaglutide, BPC-157, TB-500, CJC-1295 and ipamorelin, GHK-Cu, PT-141, MOTS-c, Melanotan II, and Epithalon pages, each with the same calculator and its own worked examples.
