im currently using p-slin and would have to say its probably the best supp ive ever had. im dropping weight (also due to OEP) and keep smashing PB's with the weights.
for the price you cant go wrong, will be a huge letdown if it is being discontinued.
EDIT: just checked out nutraplanet and my current box. i ordered it a few weeks ago when it was listed as pure supplements with the same picture etc, and recieved it with USP packaging.
its quite confusing but i dont think its about to disapear
