He's already started so why dog him? and the next person that gives him shit is getting banned. You can say what you wanna say without being rude.
Though, I do have to agree bro, I wish you would have waited to use juice. Your BF in the before pic was definitely lower than now. Keep eating big, increase your calories a lot more an eat more protein. At such a low weight for your height, you should be able to gain tons more weight, and keep most of it when you finish PCT.
Make this cycle really count, and make even more gains lifting harder and eating more.
