Depends the dosage. As mentioned previously in thread, the best results in the trial were 7.5% twice a day. At 1ml each time, that’s very expensive so most people are skimping on the dosage, and it’s too weak of an anti androgen to do that. Duterino said in one post that the trial has 3ml per administration but I haven’t seen anyone else say that. If that’s true, 6ml/day of 7.5% would be extremely expensive.
A little is better than nothing, but I think it’s about $2,400/year for 2ml/day 7.5%. That’s why a lot of people use RU. CB has a better safety profile though. I’ll consider switching to CB once I see that Corona isn’t disrupting reliability of shipment of quality product.
