“Now what I'm doing right now is the sema […] so far I'm at .25 and I have not, I'll probably have to do an update video, but um didn't notice a whole lot today yet, but it is early still”

Context: Own use, in 2021. Just before, he explains that the newly approved weight-loss pen is 2.4 mg a week and that Ozempic for diabetes is dosed from 0.25; he does not repeat the unit after “.25”.
Lower doses
Dose
“even at like 0.5 to 1 milligrams so even as low as 0.25”
Also said
“some people don't even need to titrate higher than that”
“The one that's just been FDA approved of the 2.4 milligram dose, which works well even at like 0.5 to 1 milligrams, so even as low as 0.25 some people don't even need to titrate higher than that”

Splitting the weekly dose
Dose
“even if your weekly dose is 2.4 milligrams”
How often
“on a every three day cadence, every two day cadence, or ideally on like an everyday cadence”
Also said
“if you wanted to attenuate some of these side effects”
“[…] So you cannot actually, even if your weekly dose is 2.4 milligrams, it would be more ideal probably to administer on a every three day cadence, every two day cadence, or ideally on like an everyday cadence potentially, if you wanted to attenuate some of these side effects”

Own use: slow weekly increases
Dose
“0.25 mg”
How often
“once a week”
How long
“gradually increasing the dose every 4 weeks up to a maximum of 2.4 mg”
How taken
“injected subcutaneously”
“The only thing I will note is that beyond a weekly dose of 0.3 mg, I don’t experience additional side effects but I start feeling woozy. You’ll definitely have to experiment with the dosage to see what’s best for you. HOW I USE SEMAGLUTIDE: 0.25 mg injected subcutaneously once a week (preferably on a day you are eating and training on), gradually increasing the dose every 4 weeks up to a maximum of 2.4 mg or until you see the appetite-suppressing effects you want.”

Dose
not stated
How often
“maybe three times weekly, Monday, Wednesday, Friday”
Also said
“at a low and effective dose, just enough to blunt your appetite”
“It's probably safer to microdose retatrutide or the other GLP-1 receptor agonists, maybe three times weekly, Monday, Wednesday, Friday, at a low and effective dose, just enough to blunt your appetite, promote satiation, and take away the food noise when you're undergoing a cutting phase”

Context: Said in a video about retatrutide and applied by him to “the other GLP-1 receptor agonists”; he does not give a semaglutide-specific dose. Clip published on VigorousClips; the same passage is in his full video of 31 Mar 2025.
What experts say about safety
4 statements from 2 people about risks and how strong the evidence is.
“And if you respond poorly, like, you're going to be in for a rough week, so obviously this is where titration from the lowest effective dose makes sense”

Resting heart rate
“[…] that is cranking up resting heart rate, like, I don't really know, but it is uh concerning and should at least be noted and considered before you just jump on this […]”

Side effects
“First, I’m really honest about the fact that side effects with GLP-1 medications are common. And I explain what the most common side effects are: nausea, vomiting, diarrhea, and constipation […]. Symptoms are usually mild to moderate. For most patients, they improve over time as their bodies adjust to the medication.”

Muscle loss
“In other words, adding exercise cut the lean mass loss in half. This is why adding resistance training (and getting adequate protein) are strongly recommended when undertaking any weight-loss program.”

What the research used
Context, not a dosing guide. These are the regimens used in large randomised trials under medical supervision. They describe what was tested, not a recommendation.
Fewer major cardiovascular events vs placebo; more retinopathy complications
What we don’t know yet
Trials studied people with obesity, overweight or diabetes, not lean people.
Weight is largely regained after stopping in follow-up studies.
Split or ‘microdosed’ schedules described by experts have not been tested in trials.
Compounded or grey-market semaglutide is not the same as the approved product.
Common questions
Is semaglutide approved?
Yes. It is approved in the EU, UK and US for type 2 diabetes (Ozempic, Rybelsus) and weight management (Wegovy).
Have split or more frequent dosing schedules been tested?
Not in the approval trials, which used once-weekly injections. The experts quoted above present them as their own views.
What side effects are common?
Gastrointestinal effects are the most common in the trials. See the quotes from Dr Stanfield and Derek above.
Why does the protocol section only contain quotes?
We do not give dosing advice. Your prescriber and the product information decide dosing.
