A seller on ebay offers a 99% Mucuna Pruriens extract. That stuff would be considerably cheaper than buying NOW's 15% Dopa Mucuna. Dosage recommendation on ebay was 3*100mg. Do you think all the positive effects from Dopa Mucuna like prolactin reduction and so on would also be delivered by the 99% extract or is this too concentrated? A certificate of analysis is also delivered. What do you think guys?
