Hmmm…
I’m just the opposite on the Test so far.
I have been pinning it in my thighs, but it may be a misnomer, since thighs are still virgin territory for mostly everything.
I did pin in delt once come to think of it, and it didn’t really leave any pip.
SQ has been the tried and true forever with GH and I know there are opinions about IM being better etc., but I think SQ will work.
