Most of what I knew came from Reddit.
Threads, comment sections, people who sounded really sure of themselves. That's how I figured out what to take. I believed most of it.
Finding real information on nootropics or peptides is a pain. You search a compound, open six threads, and piece together an answer from people who are mostly guessing. And some compounds get hyped like they fix everything.
I did that for years. A few things helped, and I wish I'd found them sooner. Some of it was just wrong, and I didn't find that out until I'd been taking it for a while.
"Stop taking methylene blue."
That was the whole text. It came from my aunt, with a link to a study.
I'd been on methylene blue for a couple of months. Online it gets talked about as a focus and energy thing. Nobody in the threads mentioned that it's a strong MAO inhibitor, or that it can interact badly with a prescription I'd been on for years. The study she sent spelled out the risk. I would never have signed up for that on purpose.
Nothing happened to me. I stopped and that was it. But I only knew to stop because my aunt happened to read the right paper.
What the literature says
Methylene blue inhibits monoamine oxidase A. Its interaction risk with serotonergic drugs is well documented, mostly from hospital cases where it was given alongside antidepressants. The papers below go back to 2010.
- Gillman PK. CNS toxicity involving methylene blue: the exemplar for understanding and predicting drug interactions that precipitate serotonin toxicity. J Psychopharmacol. 2011;25(3):429-36. PMID 20142303
- Charbonneau A. Risk of serotonergic toxicity with methylene blue and serotonin reuptake inhibitors. Can J Hosp Pharm. 2013;66(4):241-52. PMID 23950608
- Stanford SC, Stanford BJ, Gillman PK. Risk of severe serotonin toxicity following co-administration of methylene blue and serotonin reuptake inhibitors. J Psychopharmacol. 2010;24(10):1433-8. PMID 19423610
Retatrutide
The second one took me longer to figure out.
Retatrutide is an investigational drug. It isn't approved for anything yet. Online, people talk about it almost entirely in terms of appetite. You want less food, you lose weight, done.
For me it didn't stop at food. I stopped caring about stuff I used to look forward to. There's a word for that, anhedonia, and nobody in any thread I'd read had used it. I pulled away from the people closest to me, and it took me a long time to connect that to what I was taking.
I can't prove it was the drug. I don't think anyone can yet.
I'm not telling anyone to take it or skip it. Everything I read beforehand was upside, and that's not how it went for me.
The gap
My pharmacy knew about my prescription and nothing else I was taking. The forums knew about everything I was taking and not much about how any of it worked. Nobody had the whole picture.
So I built the thing I needed
Compound Cabinet puts all of that in one place. You look something up and see what the research actually says and how good that research is. Every entry is graded, and about a third already name the exact studies, so you can check my work.
Prescriptions are in the library too. I left them out at first because it felt safer. Then I realized I was building a tool that wouldn't have caught the exact thing that started all this. So they went in. You add them yourself, and the app never reads or imports a medication list.
There's also a journal. If I'd been writing down what changed week to week, I think I'd have noticed the retatrutide thing a lot sooner.
Comparing notes
I don't think I'm unusual. A lot of people I know are figuring this stuff out on their own, mostly in group chats where nobody's checking anything.
Next I'm building a way to share stacks and notes inside the app, with the research right there next to them. Stack cards will show names, never amounts. Notes will be labeled as one person's experience, because that's all they are.
Over time I want the notes people share to add up to their own section on each compound's page: what other people noticed when they took it. That's not a trial, and it'll be labeled so nobody treats it like one. It's just a way to see how it went for someone else.
What it won't do
It won't tell you what to take. It won't sign off on anything either. If you check two things and nothing comes back, that means nothing's on record, which isn't the same as safe. The app tells you that.
It's a reference. It isn't medical advice and it isn't your doctor. Talk to a pharmacist. They're good at exactly this, and almost nobody asks them.
I built it because I got lucky once, and I'd rather not count on that again.
