stanozolol suspended in oil is no more dangerous than in water. there is no change to the winny's chemical composition. theres just no point to suspend the winstrol in oil-if your a big company. Bacteriostatic water isnt cheap to an UG lab. Plus sterilizing your own water will take more than simply boiling tap water. Bacteria will not culture in oil as easily as it will in water. So basically an oil based suspension just helps insure your customers get a sterile product-until you have the means to create your own sterile water. Also-with an oil based winstrol-the user will have to use a larger gauge needle-which means you wont have to spend the extra money on micronized stanozolol powder. PL water based is micronized-and would be the one to buy. i got 4 in the other day-but i wont be trying any for several weeks. but, ive read tons of posts about the quality and havent heard anything negative(except for a few complaints with the pain of the high dose stuff).
