They can/will supress the HTPA, so NO its not wise..recovery is recovery.. either your on or your not..In between is NOT on, so no its not a sensible thing to do.. supports and PCT may be needed also during/after taking some sarms
Let me add, if the duration between cycles is many months, and the cycle with sarms of a few weeks here and there, long as there is enough time for PCT with FULL recovery, it can be done, but it should be considered "CYCLE".. Its pointless if you ask me!
