Don't use Letro on that small of a cycle. I would stick with Nolvadex myself. Everyone is different though. Some get no sides with 1500mg per week and then you have people like me who get it from 500 mg per week. Nolvadex has worked wonders for me. I take it at 10 mg per day until it is gone and then run it for about 2-4 more weeks after that. Some would say this is wrong, but as I said different things work for different people. Nobody knows 100% about AAS. the sides, proper PCT, etc. It's a trial and error process from what I've learned over the years. Good luck. Sorry I never responded to your question, I just haven't been on here for about a year.
