Will taking the supplement glycerol hydromax (glycerol, silica) interact with 1mg of finasteride? i'm taking fin for hair loss. thanks

No: The supplement you are taking is an overpriced placebo. Creatine and aerobic training will do you much more good. The finasteride is your business. If you're a supplementing bodybuilder, consider simply embracing your genetic heritage. Nothing looks better than a 31 year old man who's strong, trim, with some nice well-trimmed facial hair, probably some great body hair, and some macho balding.
