Longer pieces on cost, side effects, sourcing and the state of the research. Every one names its sources and dates its last review.

Compounded or brand name: what actually differs
Sourcing, dose flexibility, oversight, and what happens when supply tightens.
Why nausea peaks a few days after a dose increase
Gastric emptying slows before appetite signalling settles.
What a year on tirzepatide costs, route by route
Priced with the escalations included, not just the starting dose.
Retatrutide: where the trials are, and what isn't known
The reported results, the endpoints, and why you cannot get it yet.
Storing, drawing and travelling with an injectable
Refrigeration windows, syringe sizing, and airport security.
Semaglutide or tirzepatide
What the head-to-head data supports, and where the choice is made on other grounds.
What "research use only" actually means

GLP-1 medications for weight loss: how they work and who they suit
What the class actually does, which drugs are approved, what the trials found, and where the real risks sit.
Semaglutide for weight loss: what treatment involves
The full picture on the most studied weight-management drug available, in one place.
How does semaglutide work for weight loss?
The hormone it copies, the four things it does at the receptor, and why the appetite effect outlasts the nausea.
Semaglutide weight loss results: what to expect and when
The trial averages, the spread around them, and what the curve actually looks like over two years.
How long does semaglutide take to work?
Appetite changes within days. Weight change takes longer, and the dose you have reached matters more than the weeks that have passed.
Semaglutide side effects: what's common and what's serious
What is common and manageable, what needs a phone call, and what the evidence says about the risks people worry about most.
Semaglutide dosage for weight loss: the five-step schedule
The standard schedule, why the intervals are what they are, and the dosing mistakes that actually cause harm.
Foods to avoid on semaglutide, and why they matter
No trial has tested specific foods. Here is what the physiology actually predicts, and what clinicians consistently advise.
What to eat on semaglutide when you're not hungry
When appetite drops this far, the problem stops being restraint and starts being getting enough of what matters.
How much does semaglutide cost? Prices by route
Five routes, five very different numbers, and the one variable that matters more than all the others.
