How to inject semaglutide: what TikTok gets right and wrong

What did @thedominiquetay actually say?

In a 284K-view TikTok, someone identifying as "Dr. Taylor" walked viewers through a semaglutide injection using what they called a "1 milligram pin." The steps: dial your dose, alcohol wipe the skin and let it dry, remove both caps to expose the needle, inject straight in, press the button, wait for the click, then discard or recap the needle. That is the basic arc of the tutorial.

The framing is clinical and confident. There is no disclaimer, no mention of prescription requirements, and no acknowledgment that injection technique can vary depending on the specific pen device, dose, or patient circumstance. For nearly 285,000 viewers, this video may be the closest thing they have gotten to formal injection training.

Does the science back this up?

Mostly, yes, but with real gaps. The general sequence, alcohol wipe, needle exposure, perpendicular insertion, button press, audible click confirmation, is consistent with Novo Nordisk's prescribing information for both Ozempic and Wegovy. That is not nothing.

Where it gets shakier is the specifics. Semaglutide pens are not one-size-fits-all. The Ozempic pen comes in 0.25 mg, 0.5 mg, 1 mg, and 2 mg dose options across different pen configurations. Wegovy has its own five-dose escalation schedule. Referring generically to a "1 milligram pin" without clarifying which product, which dose stage, or which patient population collapses important distinctions. A 2022 review by Rubino et al. in JAMA Internal Medicine noted that patient adherence and safety in GLP-1 therapy is significantly tied to structured onboarding, not informal instruction.

What did they get wrong (or right)?

Credit where it is due: letting the alcohol dry before injecting is correct and often skipped in casual tutorials. Injecting wet skin can cause stinging and may marginally affect absorption. The instruction to wait for the click is also accurate. The Ozempic pen has a flow check mechanism and an audible confirmation that the dose delivered. Skipping the wait is a real user error that leads to underdosing.

What is missing is more concerning. The video says to go "straight in" without specifying injection site. Semaglutide is a subcutaneous injection, meaning it goes into the fatty tissue just beneath the skin, not muscle. Approved sites include the abdomen, thigh, and upper arm. Injection into the wrong site or at the wrong angle can affect absorption rates. A 2021 study by Whitmire et al. in Diabetes Technology and Therapeutics found that subcutaneous injection technique errors are among the most common causes of inconsistent drug exposure in GLP-1 users. The video also says to "twist off" the needle and reuse the pen, which is correct, but says nothing about not sharing pens, a non-trivial bloodborne pathogen risk.

What should you actually know?

If you are using semaglutide, the injection process matters more than most people realize. Underdosing due to poor technique is common. So is injecting into scar tissue, which reduces absorption. Rotation of injection sites across the abdomen, thighs, or upper arms is recommended by Novo Nordisk's own guidelines and is not mentioned here at all.

The dose escalation schedule for Wegovy starts at 0.25 mg weekly for four weeks, stepping up gradually to 2.4 mg. Jumping to 1 mg without medical guidance is not appropriate for most new users and can significantly increase gastrointestinal side effects including nausea, vomiting, and in rare cases, pancreatitis. The American Diabetes Association's 2023 Standards of Care recommend that GLP-1 initiation and dose titration happen under clinician supervision, not via TikTok tutorials.

A video like this can be genuinely useful as a visual supplement to a real clinical conversation. As a standalone guide for 285,000 people of unknown health status, it has real limitations worth knowing.
