first attempt at brewing.. tried masteron E at 200/ml and when it cools/stored for more than one day it crashes.. put it in a bath of warm water and it reconstitutes itself fine. no crystals at all.. here's recipe i used.
10g powder
33.5 Grapeseed Oil (GSO)
1.5ml BA (3%)
7.5ml BB (15%)

any suggestions? thank you
