Yes. It's ZestyRat. Again. Here's the whole bit.

The joke

The website has a rat in the name. It looks like it was designed for a guy who calls his garage 'the lab' and has opinions about pre-workout. It was, very obviously, not built with a woman in her forties in mind. And every single one of us orders from it anyway.

So the bit in my group chat goes: someone new joins, asks the question everyone asks — where do you all order from? — and within about four seconds six people have replied with the same word. Then someone sends the rat. Then someone sends the code. Then we move on to whose box came first.

Built for someone else. Trusted by all of us. That's the joke. It's also, as far as I can tell, just true.

The receipts

I want to be precise about what I'm claiming, because precision is the whole point of this site. I am not claiming anything in a vial does anything for anyone. I can't, I won't, and anyone who does is selling you something.

What I'm claiming is about boxes, seals and paperwork, and it's this: across a dozen women ordering from the same place over a long stretch, there has not been one missing package, one cracked vial, one seal that looked wrong, or one certificate of analysis that didn't match the lot number on the label. We check. Someone made a spreadsheet. It has never once had anything interesting in it.

Roughly three vials in ten on the open market fail independent testing — wrong label, under or over what it says, or contaminated. Against that backdrop, a supplier who is boring is a supplier who is doing the one thing that matters. The last thing I want from a vial is a good story.

What they are, and what they're not

What they are: a research-materials supplier with batch COAs on every product, a price per milligram among the lowest we track, a catalog that covers everything on this site (GHK-Cu, NAD+, BPC-157, TB-500, MOTS-c, the GLP-1s and more), and a box that turns up.

What they're not: a clinic. Nobody there checks your labs, asks what else you're on, or knows you're in perimenopause. That's the trade for the price, and I'd rather you make it with your eyes open than find out later. If you're on HRT, on a GLP-1, or on anything prescribed, read the doctor questions before you read the catalog.

Why I won't pretend to be neutral

Review sites love a list of twelve vendors ranked by stars nobody can explain. I don't have twelve. I have one I trust completely and one genuine runner-up, and I'm not going to invent ten more to look impartial. What keeps this honest is the other half of the site: I'll tell you plainly when a compound they sell has no evidence behind it, and I do, on nearly every page.

Why the code is a man's name

You'll have noticed the code is SHAUN10, and that Shaun is not a name I'd pick for myself. He's my husband. He is the one who set up the affiliate account with ZestyRat, and, if I'm honest, the one who started reading the studies at our kitchen table before I did. Somewhere in the middle it stopped being his research and became ours, and then it became this site.

So the site is mine. Every word on it is mine. The code is his, because that's the account the commission goes to, and I'm not going to pretend otherwise on a site whose whole point is not pretending. You still get the 10%. He gets to say the code was his idea. Everybody wins.

Affiliate link — I earn a commission at no cost to you. It doesn't change a word above, and you'll notice this site spends most of its time telling you what their catalog can't do.

The fine print I'd want you to read

• The compounds are sold for research use and are not FDA-approved for the uses people talk about. That's the category, not a disclaimer I'm hiding behind.
• Nothing on this site is medical advice. I'm a curious woman with a spreadsheet, not a clinician.
• The code and the link are affiliate tools. I say so on every page they appear on. I'd rather you know than wonder.
• If you want the pretty packaging instead, the runner-up is Amino Club. I keep it on its own page so this one stays simple.
