I have been using Manetabolism for 5 months consistently. I just ordered another 6 month supply. Unfortunately, I did not take a before pic, but I did a lot of trimming the first 3 months because of previous heat damage (posted earlier in this thread).
I still got significant growth even with the trims, so I am a huge believer in this product from my personal experience. My hair has never looked healthier, and other people keep commenting on it as well.
The attached pic is the difference from June 7(tank top/first pic) to Aug 16, so a little over 2 months of growth. The pics are not the best, but not to be vulgar you can really tell the difference in reference to my chest area...sorry :/.
