using winny for 3 weeks a waste?

[rx123]

I've never used winny before.

I have a bottle of win v 50mg/ml for 20cc.

if i used 100mg eod for 3 weeks what kind of results would be expected? just looking for some more cuts, hardness, vascularity before a vacation

currently 6'3 198 about 7-8% bf.

is this a waste? should i just save it for a later cycle of deca that i have?

thanks
