Semaglutide mechanism of action: hypothalamic GLP-1R binding and satiety

Previously posted:

Weeks 1-4 (0.25mg): This is your "get used to it" phase. Honestly, at this dose most people feel very little.

This is so helpful, thank you!! Quick question — does it matter what time of day you inject? My doctor said once a week but didn't specify morning vs evening. I've seen some people say evening is better for managing nausea because you sleep through the worst of it?

I do mine Saturday mornings so if I feel crappy I have the weekend to deal with it. Some people swear by evening injections so you sleep through the initial nausea wave. Honestly, semaglutide has a half-life of about 168 hours (a full week), so the drug levels stay pretty stable — the nausea isn't really about peak levels, it's more of an initial GI adjustment thing.

Just pick a day and time that works for you and stay consistent. The most important thing is not missing doses.

ngl I was expecting way worse based on TikTok horror stories. My first month on 0.25 I had literally zero side effects. Like nothing. I actually called my pharmacy to make sure I got the real stuff lmao

It wasn't until 1.0 that I really felt it kick in. So don't panic if the first month feels like nothing is happening.

Since we're talking expectations, here's a rough timeline of what the STEP trials showed for average weight loss at each phase. Keep in mind these are AVERAGES — individual results vary wildly:

So for the OP at 224lbs, a "typical" STEP-1-like result would be roughly 33lbs over 68 weeks. But there's huge variance — about a third of participants lost >20% body weight.[1]

You guys are amazing. I feel so much more prepared now. I'm going to do my first injection Saturday morning, have ginger candies ready, fiber supplements on order, and a big water bottle charged up.

I'll report back next week with how it goes. Wish me luck! 🤞
