I went crazy with the BOGO mailer from geo.I have been using their products with great success.I cant say every product is of some High purity but they all have the active ingrediants and are dosed good enough that at the price they are a steal.got meself some prami which worked like a charm last time I used it with a 19nor.The sarms 4 will be my second time using it and the stuff is really unique.The MK-677 I use with my GH.once again I used Geo and got solid effects.its just cheap enough to make it worth it. The Ai's are dosed pretty good .I will report as I use the all the stuff.
