Relentless Improvement

Hi! I am looking into trying the galantamine/choline combo and did my usual price scanning and came across Relentless Improvement who is selling 90 4mg tablets (galantamine) for $20. They sell Alpha GPC as well. This is incredibly lower than the usual 50+ prices I see when I come across Galantamind and other products. Can someone tell me if you have used the galantamine from Relentless Improvement and seen results? Or if you know it is legitimate? It seems as though $20 is too good to be true. Thanks!
