It somewhat depends on the powder we're talking about and whether or not you are going to need it to not crash in your body in the case of a long acting ester.
If that is not an issue and its a very short ester then I would say heat that shit up and swirl it around and it will suspend again, load it and shoot it.
Otherwise you would need to add more solvent to the mix, BA or BB in a small amount. If you made it yourself then u know the concentrations u used and can figure out how much to increase it by. Good luck.
Swolja-when something crashes, the juice powder crystalizes and sinks to the bottom. Tren is a bad example cuz it can be made from pellets which depending on filter methods, type of filters .22 or .45, and number of times filtered, u may have settling of binders not necessarily the tren itself.
