I haven't tried it yet, going to after cutting. Well actually my research animals are going to try it
What don't you have access to? Tren=fina thought you were contemplating that?
If that isn't an option we need to know what your goals are exactly, and how you want to get there to help much. Here is a rough estimate though(stolen from the Member store)
t1-pro = clean bulk/cutting with a little water retention
t1 = Bulk with moderate to high water retention
t-4 = Lots of 4-ad
If water retention is a big problem you can solve that with some research materials.
