I have never used propinate exclusively as a testosterone source but I have used the aratest blend and had no problems with a painful injection-however I am going to be using the short cycle theory over the next 6-8 months with just short actings like fina, d-bol and prop so I am just wondering what brands are the best and worse in terms of pain, was going to lean towards the sciomed due to cost but read here it is very painful. what ways can i minimize the pain? would combinding the trem with it help. Is it ok to use a 25g pin. Thanks alot for the input
