There is a website devoted specifically to Avage if you google "avage" you will find it. Also, BeautyProductsCompared.com has some info for you. The good news is you have the most powerful product out there IMO for anti-ageing!
Please let us know how this works for you! I am on a baby strength of Retin-A Micro and loving the results so far, even at this low dose! I couldn't tolerate the higher strengths d/t redness, flaking, extreme dryness. I use squalane and hyaluronic acid serum to counteract any irritation I get from my Baby Strength .
