I used to think that if you went into Glutes, you need a longer needle. But after reading on this site for a while, there are men and doctors who inject Test subcutaneously. So my assumption that Test has to be intra-muscular has been proven false. Both appear to work just fine.
So really - pick your needle size of choice and go for the site where it's easiest, most comfortable, etc.
I'm fairly lean except on my abs, so when I go to glutes or delts - it's in the muscle. If I were to go to glutes with a 1/2" needle, it'd probably be very shallow IM.
But rotating between glutes and delts gives me 4 sites, they are all easy to reach and see, all are painless with a 27g, and a 1/2" needle goes into the muscle - so that's my preference.
Have fun! ��
That is exactly what I was thinking. IM or sub, if both versions work, than everywhere on and in your body.
I do not feel anything on my delts, especially with this little bitty tiny needles when I am use to 23 ga.
