If someone can tell me how this is an issue based on science, I am all ears. You want it to to in IM and then into your blood and that is what it will do unless there is something I don't know.
I don't understand how you could shoot them individually, both be in your blood stream doing what it is supposed to do but not be OK to mix in a syringe but I am no
I have no idea if mixing semaglutide with b12 could affect it, specifically, but I know how it could if they reacted together in the syringe, as I barely made it through three years of university chemistry before dropping out of the pure sciences.
Generally reaction rates increase with time, temperature, pressure, surface area, and
concentration, etc etc, and it's often logarithmic or more, not linear; depending on the reactants... So if you double the concentration, the reactants react four times quicker, if you ten times the concentration of both reactants, maybe they react a hundred times quicker, or a thousand times quicker, depending on the rate constant.
That's why acetylene burns slowly and smoky in air which is twenty percent oxygen, but if you mix it with pure oxygen, in a balloon, you get a neat explosion. You've five timed just one of the reactants and got
alot more than five times the speed of the chemical reaction. It's not a linear scale.
So, in your blood stream the two substances taken separately are at X concentration, and mixed together before injection, could be X times 100,000 concentration. Basically, two reactants, (the substances) in question could take six months to react when severely diluted in your bloodstream, but take six seconds to bind together when mixed in pure form.
I'm not saying it does bind together on a chemical level when mixed in pure form, (it probably doesn't) I'm saying it
could, scientifically speaking. Personally, considering how expensive semaglutide is, I would just pay the extra few bucks and get some bac water to mix with it.
