if you run rad 12 weeks, then you need to a mini pct first before you start anything else and you need 2-3 weeks off after your mini.. you cant just stay on them all year, alternating or not... the ONLY one you can run continuously for a year without cycling off is mk677.... here is a link to the best quality mk677 you can find... https://www.sarmsx.com/nutrobal-mk-677
Since you need to run a pct after each run, it makes sense to run a sarms stack to get the best results, then run your mini pct, take 2-3 weeks off, then start another stack. Because if the suppression you can't just keep staying on sarms. You still need to pct and recover
