Hello ladies, I was wondering if any of you have any experiences with DNP & wether it affected your periods. A girl I know recently did T3/50mcg & DNP 200mg per day 7 days on, 7 off, 7 on again. But she has not had a period since and she's about 5 weeks late. She's done 2 pregnancy tests, both negative. If anyone can shed some light on this it will be greatly appreciated. Cheers.
