A lot of those tren mixes like super tren or tri/tren have test prop mixed in with it. Not all but a lot of them do. Either way, I've found that most UG mixes of anything will typically hurt a lot more then just plain old regular gear. These mixes are pure garbage IMO.
Div is right, a massage and soaking in Epsom salt should help, but I've had some knots so bad in the past that no massage was going to work it out...in those cases waiting it out is all you can do.
Last thing, Div is also right about the soreness being part of the game, but in my opinion it should never be so bad that it causes you problems. If it does, find some different gear.
