I dont know much about this but I saw a PH company adding this to their products.
Carbopol is a time-release agent added to our prohormone compounds in order to release the prohormones over a longer period of time. This sustained release action mimics the body’s own production of hormones, which improves efficacy and absorption. In fact, Carbopol may increase effectiveness of prohormones by up to 100%! This means that prohormones that include Carbopol can be far more effective at building muscle and decreasing body fat.
I found this write up so it looks promising.
