I have been reading about 1test and 1-AD. I know that they are close to being the same. I'm not clear on the difference if there is any. I was wondering if anyone has had better gains with a topical over an oral. Or if anyone has found a certain company that makes a product that they feel is better than others. I'm either going to try the 1AD made by Ergopharm or else the Dermocypional TD by Global Nutraceuticals. If anyone has any information that will help I would appreciate it thanks.
