well for the price it is the best sostenon out, but compared to the other brands its not as potent......I enjoy shooting 10cc's at once,the pain is not bad either like other sos'........but I think if you have the money just buy the redis, omna, or portuguese ones, hell I like it though, you get nice results, like I said I use it because of the price, 30 bucks for 2500mgs, if you have some just take about 3cc's every other week, that will be cool, you will get some water the first week, then it comes out......havent used any in three weeks, and I notice a bit of puffyness and water retention is down, but I would recommend it for guys who can only afford cheapman's cycles.
