Most suppliers distill the compound in either propylene glycol or ehthyl alcohol depending on which will hold the solution at a more stable level. Propylene glycol tastes a lot worse than an ethyl alcohol blend. I’ve ordered from probably 10 different suppliers and can guarantee you that choice sells legit sarms. They’re stabilized in liquid solutions because 1) most sarms tend to lose potency in powder form and 2) liquids make it a lot easier to dose. You’re fine, don’t worry 🙂 I like to wash mine down with orange juice or lemonade. Swallow a ml and flush down with cold juice – works like a charm.
After saponification, the lipid extract, called “unsaponifiables”, may contain other lipids besides sterols including hydrocarbons, carotenoids, tocopherols, free fatty acids, and other triterpenes. Many researchers proceed with derivatization and GC analysis without further sample cleanup and do not have problems with interference by these compounds. This is usually acceptable for the unsaponifiables fraction of a refined fat or oil sample. However, in some samples, such as crude oils, it may be necessary to further purify the sterol fraction from polar unsaponifiable lipids. Silica, C18, and aminopropyl SPE cartridges have all been used for this purpose. Phillips and co-workers  used aminopropyl SPE columns to separate sterols and stanols from serum unsaponifiable lipids, using chloroform: isopropanol for elution. Toivo and co-workers  demonstrated that equal yields were obtained using either C18 or silica SPE columns and eluting the sterol fraction from either column with 5% methanol in chloroform or 1% isopropanol in hexane, respectively.
