Its not the SA that smells, its the changes in your body chemistry from coming off cycle and the SA changes combined, kinda like Goats when they rut odor, lol! It will do that sometimes even when used solo, its also a good indication to decrease your dose or take some time off, being a non-hormonal, theres a limit to what it can do for you and after 5 hours its absorbed and safe to wash, that doesnt mean you wont still have some elevated personal pheromonal activity going on. Its best to cycle it and alot of guys are. Women can use it too. Any libido enhancement is brief and probably placebo ask any one whose used it regularly. Its just my opinion
