Questions about Tribex-500?

I’m getting ready to do a six week cycle of Tribex-500 and M, and I had a few questions.

My first question is, will Tribex or M accellerate hair loss if you are already losing your hair? Does it increase DHT levels? Would it be a good idea to use a product like Nano shampoo during the cycle to help prevent any hair loss.

Thanks,
Joey
