through reading up on how to inject, needle size, and where to inject, the only thing i don't understand is the areas you inject. I thought the main areas were the upper glutes, deltoids, and thigh. I find threads siting injections in the chest, biceps, calf's, and traps. are these areas necessary? is it best to alternate with all these sites? or can you do away with just thigh, glute, and deltoid, alternating them?
Ive also found some people saying they inject into the muscle they work out that day, where others say not too, being it could burst. any thoughts
