Has anyone used Trilastin-Sr for stretch marks?

Im 5 months pregnant and i've been using Bio-oil to help reduce stretch marks and it doesn't seem to have helped much at all. I cant even tell im using anything. Recently i've heard about Trilastin and I was wondering if anyone has anything to say about this product. Good or bad. If anyone has any other suggestions about a good product i would really appreciate it. Right now I don't think obsessive weight gain is an issue. I've only gained 5.5 pounds, i use bio-oil and cocoa er, taking vitamins, drinking plenty of water and OJ (i heard b/c of the high levels of Vitamin C its good for stretch marks) but so far nothing is working =[ Am i just doomed to have horrible ugly stretch marks no matter what i do?
