Provita IMO u need to forget gaining LBM and dropping bf% if u are at 10%bf.. period.. at 10%bf it is hard enuff to lose fat and not lose muscle, let alone gain it! IMO it would be damn near impossible. u may be able to make some lean gains where u maintain bf% but IMO this too will prove to be nearly impossible. with the right compounds and diet maybe but at 10% bf ur window for error is pretty small IMO.
if u want to make gains i suggest u try to come up with a lean bulking routine.. if u want to drop bf% i suggest u come up with a method of cutting where u do it slow and preserve most of ur LBM..
quit trying to do both because IMO its not gonna happen. on a side note in the event u do figure out how to gain LBM and drop bf% at a 10%bf starting point i expect im not alone in saying please share this info!

(tren may be an option but im speculating as ive never run tren or any AAS cycle)..
