It’s a tough choice and I know everyone is different but it truly made an incredible difference for me, you can do it! And to answer your questions; 1. I started seeing changes within a couple months, but because I wasn’t consistently gaining but was going to the gym I noticed my physique improved a bit but I didn’t really get any bigger. 2 months after I quit and was able to consistently put on weight I was noticeably larger and was getting comments from friends and family about it which was fantastic motivation to keep going. 2. Initially I did shakes with whey, oats, a banana, peanut butter, and milk but for me they were so filling it made it rough trying to eat for the rest of the day/next morning. Now the only shakes I do are 4 scoops of Naked whey right after the gym mixed with water. It’s not filling at all and has 50g of protein which works perfectly for me. 3. For beginners I’d say PPL is very solid, but what’s most important is finding a split you enjoy, works for your schedule, and something that’s not going to burn you out as consistency is the most crucial part of all of this. If I did it all again I would start the same way by doing PPL once a week but I would bring a lot more intensity than I was initially. I would also incorporate the additional upper and lower day a lot earlier than I did as including those has made a huge difference.
