The people getting the most out of retatrutide have one thing in common: they actually track it. Not just "did I inject," but the full picture, so eight weeks in they can answer whether it's working.
Everyone starts in a spreadsheet or the Notes app. It works for about two weeks. Then you add a second compound, you start wanting to note how you slept, your bloodwork comes back, and suddenly you've got numbers in four places that don't talk to each other. The whole point of tracking is to connect cause and effect, and scattered notes can't do that.
Good tracking is boring and consistent. Here's the stuff worth capturing:
Each injection: what, when, and where (site). If you rotate sites, track the rotation across your whole stack, not per compound, so you can see the pattern.
The headline number, but don't stop at weight. Waist and other measurements tell you about composition, which the scale hides.
This is the part people skip and later regret. Energy, sleep, appetite, mood, GI stuff, anything you notice. Log it daily-ish next to the protocol, and over weeks the patterns surface. Symptoms with no dates attached are just vibes.
A lot of the reta community now does "bloodwork journeys," reviewing markers like metabolic, liver, thyroid, and lipid panels with their clinician over a cycle. Whatever you and your professional decide to watch, the key is holding those results next to your protocol and your symptoms, in one place, so you can line them up instead of squinting at PDFs in your email.
Before or right as you start, capture where you're beginning: weight, measurements, how you feel, and any labs you have. "Better" is meaningless without a starting point. The baseline turns a pile of logs into an actual before-and-after.
The tracker you'll still use in month three is the one that takes ten seconds a day. Make logging fast, keep everything in one view, and set a baseline on day one. If it takes effort, you'll quit, and a tracker you quit is worse than no plan because you'll think you have data and you won't.
If you're also taking supplements alongside the peptide, track those in the same place. The interactions and timing only make sense when you see the whole stack together, not peptides in one app and supps in another.
Disclosure: we build StackSense, so factor that in. We made it because tracking a stack across a spreadsheet, a notes app, and a camera roll full of lab screenshots is exactly the mess described above. StackSense puts the whole stack (supplements and peptides, 420+ compounds), your symptoms, and your bloodwork in one timeline, with a baseline so progress is measured instead of guessed. It runs as a web app, so you add it to your homescreen on any phone, no app store needed.
It's a tracking tool, full stop. It doesn't tell you what to take or how much, and it isn't a medical device. It just keeps your data honest so you and your clinician can see what's going on.
One timeline for your whole stack, symptoms, and labs.
Track your stack with StackSenseAt minimum: each injection (what, when, site), bodyweight and measurements, how you feel day to day, and any bloodwork you review with your clinician, all against a starting baseline. The symptoms and the baseline are the parts people skip and later wish they hadn't.
Yes, and you should keep them in one place. A stack only makes sense when you can see everything on one timeline. Apps that only do peptides force you into a second tool for your supplements.
No. This is about organizing your own data. Anything involving what to take or how much belongs with a qualified professional.
This is a tracking and organization guide only. It is not medical, dosing, or treatment advice, and StackSense is not a medical device. Work with a qualified healthcare professional on anything you put in your body.
