Microdose vs standard dose: the honest comparison

A standard dose is the labeled maintenance dose with trial evidence behind it; a microdose is a below-maintenance dose with no weight-loss outcome evidence. The honest framing isn't 'which works better' — it's 'one is proven and one is unproven, at a lower price and usually with fewer side effects.'
The full picture
Standard dosing is what STEP and SURMOUNT studied. A microdose is a commercial choice to use less drug. The appeal is real — lower cost, gentler side effects — and for some people, guided by a clinician, a lower dose is a reasonable individualized decision.
What it is not is evidence-equivalent. Assuming a microdose delivers standard-dose results at a discount is an extrapolation the data don't support. The price is verifiable; the efficacy is not.
So the decision rule is: treat a microdose as a lower-cost, lower-dose, unproven strategy, and make it with a clinician who knows your history — not as a proven treatment you found cheaper.

Frequently asked questions
Is a microdose as effective as a standard dose?
Unproven. Standard doses have trial evidence; microdoses don't.
Why choose a microdose?
Usually cost or side-effect tolerance, as an individualized clinician-guided choice.
