BTG Oxandrin comes in 2.5mg and 10mg tabs. The 2.5mg's are white, oval-shaped, the 10's are capsule or bar-shaped. If it's from a compounding pharmacy though, it could theoretically be made to any dosage, color, and shape. I believe BTG is the only brand-name of oxandrolone though, so if you have Oxandrin, it should be either 2.5 or 10mg... what brand do you have?
