This is taken from AnabolicReview:
"Another way to avoid the liver and consequent de-struction of the substance is to grind up the Primobolan tablets in a mortar and consume them together with heated vitamin E oil. The Primobolan/vitamin E mixture reaches the blood similar to Andriol that is the absorption occurs through the lymph system and the solution does not reach the liver through the portal vessel. "
Other than consuming grapefruit juice 15-20min. before taking it, I doubt you will find much else.
Why not just get the injectable, it is 100% bioavailable.
