This isn't exactly the same but I was taking 0.625 mg daily for the best part of 6 months. I'm a receder so the scope for regrowth is small BUT it was a success. My hair improved in terms of thickness, tighter hold and minor regrowth. It definitely was doing the job and I am only on finasteride.
Recently I put it up to 1 mg a day as I am coming up to 6-12 months so want to maximise any possible additional benefits. I highly doubt it will make much difference but trying it out.
interesting...
