I would run your pct first for a little while, then start your SARMs, and Lr3 IGF-1 , as the sarms will suppress natural testosterone from my understanding, so i would wait until your done your post cycle meds and then start. You can use the IGF-1 lr3 during your pct to help keep your gains and then start the anadarine S4 and Ostarne mk-2866 later, and stay on the igf-1 and up the dosage from what you used it at during pct.
Thats probably what i would do.
