I don't personally know of anyone either, but from my research ph's seem to be very harsh on the body. As far as long term effects go its unknown. I am not aware of anyone that has been using them for 30+ years to see the effects on the body. It's a crap shoot as far as I'm concerned and I usually stay away from the harsh Ones. I feel safer with aas because there is far more research available, and actual living examples of long term use. I would tread carefully with them and stick to the milder ones mostly, and limit use of the harsh ones as much as possible. I usually stick to injectables and rarely use orals. I may use orals a total of 12 weeks a year at the beginning of blasts.
