They both do the same thing in theory, reduce SHBG, but blueup doesn't have a AI in it, JW has the ATD variant in it. So wont blue up cause probloms estrogen wise? I was on JW for 20 days it was amazing, i started getting wierd heart palpuations and **** so i stoped it, pretty sure it wasn't related to JW, its been about a month i started jw again today, so i got 10 days, should i go back on JW or get the 15.99 BU, i would love to play that great price for BU but there is no estrogen protection right? Also can i just skip to BAM or should i go through JW again?
