Easy.
1. I've used all three and I feel recovered in days with torem on the harshest of oral cycles. Two weeks with Clomid and about the same with Nolva.
2. Look at the medical studies: torem vs Clomid and torem vs Nolva. Torem is just as effective as Clomid in restarting hpta and just as effective as Nolva in preventing gyno. Easy to find Google it.
3. So it does the job of both. Clomid will not effectively prevent gyno and Nolva is all but discounted medically as a protocol to restart hpta. Nolva will restart you but that's not its primary function.
4. No sides with torem. I feel great on it.
