Detalhes da empresa

  1. Serviço de Informações

Escrito pela empresa

Fat Scientist is a free online resource built for people using GLP-1 medications like tirzepatide (Mounjaro, Zepbound) and semaglutide (Ozempic, Wegovy). We specialize in tools and educational content for users of compounded versions of these medications, which come in multi-dose vials and require precise dosage calculations. Our suite of calculators helps users convert prescribed milligram doses into exact syringe units based on their specific vial concentration, calculate split doses for improved tolerability, estimate medication costs, and plan their treatment timelines. Every calculator is free, requires no account, and works on any device. We built Fat Scientist because compounded GLP-1 medications present a unique challenge. Unlike brand-name auto-injectors with pre-measured doses, compounded vials require users to do math that directly impacts their safety. A wrong calculation means injecting too much or too little medication. We believe nobody should have to guess when it comes to their health, and the tools to get it right should be accessible to everyone. Beyond calculators, Fat Scientist provides guides on topics like reading vial labels, understanding concentration values, proper injection technique, and navigating the differences between brand-name and compounded medications. Our FAQ library addresses the most common questions we see in GLP-1 communities, written in plain language without medical jargon. Fat Scientist is operated by Productist LLC. We are not a pharmacy, we do not sell medications, and we are not a substitute for medical advice. Our mission is purely informational — giving GLP-1 users the tools and knowledge to use their medications safely and confidently. We are funded by voluntary donations from our users, not advertising or affiliate deals, so our recommendations are never influenced by commercial interests. Whether you are just starting your GLP-1 journey or adjusting an existing regimen, Fat Scientist is here to help you get the numbers right.

Super helpful tool!

When I switched to compounded meds, I didn't understand the difference between volume, concentration, dose or about how to figure out my dose. Some knowledgable users directed me toward Fat Scientist and it was exactly what I needed. The user guides are really helpful and I still use it every week to calculate my dose. It’s incredibly helpful when I’m finishing up one vial and need to get the rest of my dose from a second vial. I could never figure that out without this tool.

User Friendly, Tons of Digestible Info For Beginners

This ingenious calculator

This ingenious calculator was smart enough to tell me, "wait are you sure you put in the correct numbers? Because that's unusual." I double checked and sure enough I did. Such a great tool! Thank you for creating it!

Essential for the new GPL1/GIP user

Site is a collection of dose calculators useful to GLP1/GLP-GIP users.

Site is intuitive with several options that fit with many, if not most dosing regimes. Calculations made with the site are accurate (the math maths).

Essential for the newer user who may be struggling with changing suppliers who provide different medication strengths. Allows users to make sure that the provider instructions are correct.

I always check Fat Scientist

Since I switched to compounded tirzepatide (from name brand single-use vials), I always check Fat Scientist for my dose when I change doses or pharmacy/concentration. So glad to have found this through Reddit.

Absolutely crucial tool for anyone injecting GLP-1s with a syringe and not a pre-loaded pen

This is indispensable if you want to avoid dosing errors. Whether you're new to compounded GLP-1s or are switching doses or concentrations of medication, you're always going to want to double-check here to make sure you're doing it right.

Resposta da Fat Scientist

Thanks Mike! Syringe dosing leaves a lot more room for error than a pre-loaded pen, so having a reliable double-check in your corner really does matter. Really glad Fat Scientist can be that for you.
