There are a lot of factors that can go into this. The biggest factors are how many blood vessels the area has, the amount of the drug, the and the materials used to make the drug.

If the amount of drug being injected is small enough, it doesn’t matter which area you inject into, as long as it’s one of the preferable areas, like the butt, shoulder, thigh, etc. If it’s on the bigger side, then it will have to go into the butt, which has the most vessels and has the biggest mass of any muscle. If it’s too big, then it will have to be inject into a vein (IV) instead of a straight injection.

On the other hand, if the drug is meant to be slowly absorbed, then it may be injected into the arm or some other area where the vessels are used slightly less.

And of course, if the materials are dangerous in one area, then another method will be used. For example, if a preservative is dangerous if injected into a muscle, then it will be injected into a vein instead.

Hope this helps!
