prop kicks in in a few days...
NOT all prop is the same... that is absurd... different pharmacies get different powders in different grades... all pharmacutical grade prop is essentially the same, but then im sure there are several different carrier agents used throughout the industry... UGL's may source their powders from china and there is no way without CMCG testing to verify the exact purity... over the years several sources have had 'bunk' gear come from brewing with 'weak' powders/raws...
from my experience, testolic is good to go...
