Does anyone know how to prevent or minimize soreness in your quads after a tren injection? The tren is 100mg/ml made from a universalkits conversion. I don't get the soreness in the glutes when I do the injection there. I am adding 1cc of B12 to the injection. I need to know something since I have to rotate injection sites due to eod injections. The quads will be coming back around on the rotation next Tuesday. I am currently rotating between both glutes and quads.
