Prob hormone ??? You would never use a pro hormone in PCT or ever in my opinion. If you don’t trust the source then yes don’t take it. There are a lot of people that will tell you even the simplest of PCT is ok but that’s debateable between person to person. At the very least you should run chlomid, Nolva and a test booster like Post CT if this is your first PCT you are most likely going to struggle and you want all the help you can get to get yourself back on track
