The semaglutide hate that comes up in these threads makes me really sad lol. And kind of defensive? which I know doesn't make any sense because obviously it's nothing personal, but it's kind of like when a bunch of people shit talk your favorite band or something.
As other people have said, sema is good for stacking if you want to go that route because it's the only single GLP agonist so stacking it will hopefully cause less side effects from over activating a bunch of pathways at the same time, if that makes sense.
Also semaglutide is much cheaper than the rest -- I don't understand why people claim it's not. You can pretty easily find a 30mg kit for less than $120. Each vial would last ~3 months if you did the highest prescribed dose. An equivalent kit (in terms of top dose) of tirze would be 240mg, which doesn't appear to be readily available. So let's compare tirze 60 instead, which a lot of vendors carry. It ranges in price from $150 (usually a sale) to $250 to even more, although I'd say mid 200 seems to be the average. Each vial would only last a month at the highest dose. The price difference is stark.
That difference is actually why, I believe, a lot of vendors don't seem to offer sema as much anymore -- a lot of people have switched to newer offerings, or just never tried it, plus it costs so little that there's not a huge benefit for vendors to stock it. Why would they, when they can only reasonably charge ~$60 for a 10mg kit that would last 40 weeks, vs selling a 60mg kit of tirze that lasts the same amount of time but costs 3-4 times that amount?
