Weve gone over ostarine use in pct time and time again when it comes to pct and honestly its getting tiring continually explaining it... Ostarine CAN be mildly suppressive with EXTENDED use... Four weeks usage has shown no suppression unless the dosage was abused... None of us ever recommend anything over 25 mg which is fine for pct... Many of us have used it SEVERAL times with bloodwork... Its how its used... Ive put endless hours of testing and use on this... I think i have a good idea how this works or i wouldnt be recommending it.. I have YEARS of study into this... This is why everyone comes to me on MULTIPLE forums all over the internet for guidance on sarms and it is showing with the constant growth in popularity, use and results... S4 is the suppressive sarm that is not to be ran in pct... Osta is beneficial in pct for a multitude of reasons and as stated before, theres bloodwork EVERYWHERE that shows no suppression after pct... Its excellent for pct and has been a staple in pct for quite a few of us for quite some time now...
