watsup guys. i have a quick question. in the summer i used crystaline dnp each cap containing 250mg. well i have 30 caps left and i want to do a quick 8 day cycle this week before a trip to cancun. the thing is i tried in the winter and afetr 3 days i saw no side effects associated with dnp such as sweating or yellow sperm. Can dnp have lost its effect meaning the caps are useless now? because in the sumemr it worked great and i saved the remaining caps that i have in my bottle. its been sitting on my counter since august. how can i test to see if its still potent? should i put on 2 pair sof ruibber gloves and open one cap up in the backyard and see if the rgass turns yellow upon contact?
