i am on week 5, gonna be 6 weeks. 100 mg a day 4 times a week for the past couple of weeks, before that was doing 75 mg 5 days a week, i think the 1st week i did 50 mg 5 days a week. gained about 5 lbs. so far. tough for me to comment on pros and cons because it's my first time running a hormonal/steroidal compound. most noticeable was the endurance and recovery improvements. i felt that strength went up too, but nothing too dramatic. downside is the back pumps and pressure on my side, and it feels like my liver is working too hard, altho that could be a psychological effect. libido has been great, noticed some mild testicle pain and reduced energy on off days. i impulsively jumped into this w/o serm or proper support, but it seems to be turning out ok. still might grab the serm, idk.
