I have ad supertest 500 that wasnt pleasent, but neither of which are as bad as test suspension. again a lil sterile oil and being warmed a bit help. Id say just grit your teeth and take it like a man lol, but then again i teared a while back when i did site injections of test suspension in my calves. lasted through 2 shots and decided that since i probably wasnt going to get any more that localized swelling (that was confirmed from a post on here) id pass.
