I must be lucky but I have never had noticable side effects from
clomid or nolva. In terms of pin gauge, if you are injecting into glutes, a 21 will do the job. When you use finer gauges, you will spend an extended amount of time just trying to force the contents in. Not easy if you are injecting into your glute. A mate of mine has even used insulin needles on oil based compounds. I asked how many hours he spend trying to draw and inject.. He just laughed..
I inject in the glutes and generally dont have any pain problems. Except when I use
cyp. My body just doesnt agree with that stuff.
If you havent already, have a squiz at
