I agree with the above post. I've used both products and from my experience: I Used revivogen for 6 months consistently, and have also been on and off it longer than that. I was using 25mg RU58841 on the hairline only and revivogen for the rest. I almost lost my crown. If revivogen works at all it wasn't strong enough. I since grew it back using RU and now CB-03-01. I'm still using lipogaine, after trying it for nearly 4 months. But I'll be saving my money and going back on generic minoxidil as I'm not convinced it's any better.
