Best for my brothers training

[ninesecz]

My brother is 41 and is in great shape! He has been riding semi pro Motocross for 25 years! He has ridden with everybody from Davey Yezek to Todd Dehoop to Ricky Carmichael , Jeff Emig. He is too old now to compete with the younger guys so he is concentrating now on Marathons and Triathalons. He is already very good he takes top 30 in every event and some have over 200 entries,
I was talking to him and he is interested in doing a cycle that will help him with his speed and agility. I all set to do a cycle of Winny (8 weeks @ 50mg ED)
I was figuring to not give him side affects but still get some good gains to run the Winny buy itself. He does not want to get into any type of injectables and will not want to stack anavar with it. What do you guys think?
I know there are a lot of UFC guys that do this and I imagine some other athletes too! he is not looking for a miracle but maybe just taking 10-15sec off of his average mile times in his marathons.
any advice

the problem with winny is that it dries out joints, and for someone his age i don't think that would be desirable, especially during marathon runs

personally i wouldn't use it for him
