I get it, but really it not difficult to use the search function. All the answers to your questions are already there.
But i’ll answer your questions anyway.
First off, you really don’t need to use the induced follastatine or the myostatin fields at all. Why? Because Arms shredded and jacked, leg shredder, chest and back all contain the Muscles Beyond Limits field. If you actually read the description of the muscles beyond limits field, you will see
Do you see this? It already stops the production of myostatin in your muscles cells for those specific body parts, so you really don’t need to be wasting time using the follistatin or mystotatin fields. I guess you could potentially have some extra gains, but probably not much. I’d rather save my time for more fields.
For Extreme Muscle Growth YOU NEED TO TREAT IT LIKE YOU ARE TAKING A STEROID, because of the WARNING IT GIVES
Do you see that? That’s why you need to really read the description of these fields! If you abuse this, it could cause balding, excess estrogen which could lead to gynecomastia (man boobs), etc. all the side effects of abusing steroids, the exact same things.
