it is shipped 2 you with a cold pack while in pellet form, it must be kept cold to help keep the pellets together (binders and glues) since you probably wont be needing them in pellet form any longer you dont need 2 keep it cold. As far as the baking process goes, I do it every time why take the chance of having dirty fina, all the filtering and whatnot is 2 filter the good from the bad it is in no way a sterilizing process thats what the baking is for... and 2 find out the real mg per ml, each kit is intended 2 yeild 75mg per ml.. 2000mg tren = 1 cart / 2g conversion kit is needed and will convert to 75mg per ml.
