i've mentioned this before, but i would recommend that if you're new to the game, you hold off on giving them a try. use a lab that you've got solid references on, that you've heard from experienced people is dosed properly, etc.
try to find reviews for the SPECIFIC compounds you are wanting to use if you can. quality of compounds can often vary even within the same lab. there are many reasons for this (quality of powders, quality of the different chemists they are using, their choice to underdose more expensive compounds, etc. etc. etc.)
if you don't have something to compare it to or someone you know that has experience that can compare it to other things, i'd wait and do a cycle or 2 of someone trusted and try biogen out when you'll actually be able to know its quality just by taking it.
if you are going to try it anyway, get your bloods down mid cycle and post cycle in addition to pre-cycle and you can use those figures to give you a general idea.
