I've read the max recommended amount is roughly 0.5ml if going sub q to prevent redness/swelling/lumps but what about concentration? 0.5ml of 250mg would be 125mg per shot. I know a couple of guys who are on TRT and are injecting much lower dosages, 100-200mg a week compared to someone who's cycling at let's say 500mg so they are averaging 30mg to 66mg per shot sub q.
Would using a higher concentration of test (e or c) cause more pain or bring any trouble with it?
