Okay there is alot to answer here so hold on tight this will be long winded lol...
Okay firstly, UB bovine source is from US cattle, BB bovine source is from Argentina or New Zealand cattle, that one always confused me as to which one it was lol. Some people think BB is safer than UB, it has been debated some quite a bit, but also UB customer service is better than BB. BB isn't that secure, they had a lady steal customer's credit card information! I took UB and I feel fine with that decision, really ANYTHING you take no matter where it's from is a risk. Unless you see how each capsule is made first hand, you will NEVER know it's 100% risk free. This includes BB, UB, herbs, vitamins, etc. etc. etc. So really to me I went with UB. And you can use a bank card with the medplex UB site, I used my debit card when ordering. I don't own a credit card. Me and hubby built our credit with loans and other things.
Now as far as NB. It only made my previously saggy boobs firmer and more perky, it NEVER made them saggier, nor did they become any weird cone shape you are speaking of. They are very round now, in a bikini I get asked if I have implants! As far as nipples. I have big areolas already before NB because I had a kid and I breastfed. I didn't cover my nipples while pumping and I never noticed an increase in their size, nor any other abnormalities with them. I also only used padding with the XL's for the first few months of using them, when I used the mediums and larges, I didn't use any padding. After a few months on the XL's I stopped using padding, I was using campers tape. I haven't used padding since and have NEVER had a problem with indentations. As long as you don't over pump, watch what you are doing, keep an eye on it, you will be fine. If you are unlucky and start getting indents there are plenty of padding methods you can use. I personally didn't like the soft cup rings, I ordered them when I first ordered NB with the medium domes. They didn't agree with my sensitive skin, lets just say that lol.
Okay as far as protein, protein is very important in NBE, the scientific reason as to why, I have no clue. But I can tell you when I was taking UB, I would get 80-90g of protein everyday in my diet and with protein shakes to supplement and I noticed when I got that amount, I got the most growth, more growing signs, etc. When I slacked on the protein, I didn't grow as much, didn't feel the growing signs, etc. As far as protein brands, I recommend the NOW brand non-flavored protein isolate. You can mix it in ANYTHING. I use to bake brownies with it, mixed it in smoothies, mixed it in chocolate or strawberry milk, etc. etc. etc. I even put it in soups! It's very versatile.
Okay now for dome sizes, I was a 32B when I started NB, so the equivalent of a 34A, so same size as you, I went with the medium domes. I used the mediums a good 2 months before needing the L's. I personally do use the airlocks as I do the pump and hold technique and find them very useful to me, but do what is best for you.
I hope I answered everything, if I missed anything let me know lol.
