What you get, what you may do with it, and who to write to.
Last updated 21 October 2026
A PDF. One file, delivered as a download, listed on its own product page with its page count and the date of the edition. There is no physical object, no subscription, no membership and nothing that renews.
Immediately. The download link appears on screen as soon as the payment goes through, and the same link is emailed to you by Gumroad at the address you entered. Nothing is shipped and nothing is queued for later. If the link does not arrive, check the spam folder first, then write to awheytoexplain@gmail.com and it will be re-sent.
The same licence is printed inside every book, and this is it.
Your copy is licensed to one reader. You may read it on as many of your own devices as you like, print it, mark it up, and take it to your doctor or your coach.
You may not resell it, redistribute it, give away copies, upload it to a file host, a forum, a course, a group chat or a training site, or reproduce any part of it commercially, without written permission. Quoting a short passage with the book named as the source is fine and always will be.
The text, the layout and the artwork stay the property of A Whey to Explain. Buying the book buys you the right to read it, not the rights to it.
Gumroad is the merchant of record for every sale here, which means Gumroad takes the payment and Gumroad handles refunds, chargebacks and disputes. The refund window on these books is seven days.
Ask for it through Gumroad, from the receipt email or at gumroad.com/help. No reason has to be given. You keep the file, because taking a PDF back is not technically possible and pretending otherwise would be theatre.
This page describes how that works, it does not add conditions to it. Nothing here limits any right you have against Gumroad as the seller, or any right you have under the consumer law where you live.
They are educational. They are not medical advice. Nothing in them diagnoses, treats, cures or prevents anything, and nothing in them is a recommendation to use or to avoid any substance. They carry no dose, no route as an instruction, no protocol, no cycle and no source.
Every status and every figure describes the published record at the time the edition was written. Evidence moves and regulators change their minds, so each book prints its edition date. If you find an error, say so and it will be checked, and corrected in the next edition if you are right.
None of this replaces a conversation with your doctor or your pharmacist, and that goes double if you take prescription medication.
No brand paid for a mention, no entry is sponsored, no product is named as good, and there is not one affiliate link in any book or anywhere on this store. If that ever changes it will be written at the top of this page in plain language, not buried.
awheytoexplain@gmail.com. One person reads it. Corrections, download problems and licence questions all go to the same place.
