Subq goes past skin and in your fat and is absorbed that way, Im goes past skin fat and into your muscle therefore you need a longer needle

What lengths really depends on how fat you are because it needs to go through all fat so more fat = longer needle

At your lower bf, 1/2 inch is plenty. I use 1/2 for most things IM except glutes and I am at a higher BF% than you.
Worse case scenario, if the needle is too short just press past the fatty layer. Problem solved on the spot.
That was the end of the thread
