MinoxidilMax now carries topical dutasteride and RU58841 with a report of analysis for RU. There was discussion awhile back on the authenticity of the products at this website. Has it been determined if this company is legit? And is it true that PG is important for absorption of topical solutions? I've been using non-PG products with little improvement so I'm wondering if I need to use products with PG as a carrier instead.
