Currently using Massmax XT + Prime right now. Looking to add a little more Rhaponticum to the mix but does anyone know of a good source that has been HPLC tested? Thought about bumping my massmax dose up to 6 a day if I can't find any straight rhaponticum to add. The only other good source I have heard of was mass pro synthagen x2. I was looking at primeval labs super rhanderol and asked about sourcing/HPLC but haven't heard anything back so I am assuming that was a big no. Thanks for the help!
