You are correct. Semaglutide is the least expensive because the required dose is lower. From overseas sources, all of them are about $1/mg. However, the max dose of clinically approved sema is 2.4mg, while tirz is 15mg and reta is 12mg.
My buddies are experimenting with Reta, Tirz, and Sema, but I'm unsure what the correct starting dosages are. Also, what's the weekly increase, and is it safe to combine them?
Good point about mixing. I've been thinking about what happens if the power goes out. I have some peptides that are supposed to stay cold. What do you do if the electricity is out for days?
