I've used Newport Test C, Tren Ace, Cialis, and Arimidex. I felt the oils were well dosed, very smooth, no pip that i experienced. Ran 500mg/wk Test C and 50mgs trenA every 2nd day. Arimidex worked well, .5mg every 2nd day. The Cialis could have been stronger in my opinion. Had all the tren sides after about 6 days. night sweats affect me bad. Good strength gains, felt great by week 6... Ran cycle for 12 weeks and gained and held on to 25 lbs. Did Not use Newport for PCT as had HCG and Nolva from other suppliers.
