My favorite test is prop by far and am currently about 7 weeks in on a prop cycle. It kicks in very quickly and causes little or no water retention which is what you want. One draw back is the need to shoot frequently but the benefit of the quick kick in out weighs that. (IMO) The clomi/nolva will take good care of you and i think you will be very pleased with prop. Depending on your diet and lifting intensity you can put on some serious lean muscle. Good luck bro
