The ultra green maeng da capsules I purchased the 60 count and the onset was about an hour but when it began to work I was full of energy and pain free I suffer from degenerative disk disease and subluxations and arthritis and all my pain was gone with a blast of energy, bravo bravo. I would like to sample some other strains that yall carry if I'm as impressed with the other strains as the maeng da I will make a large bulk purchase.
