If ya wanna play with suction, get a Lansinoh Affinity Pro Double Electric Breast Pump from ebay. If you search long enough, you can get one for 15 bucks. There is a rhythm to it, one that helps the cologine expand better.. problem is, most recommendations say use these pumps 10 to 12 hrs a day at a low pressure..
But here's the thing, all the results from studies show no evidence on the majority, and some that did show growth are those who actually were doing during their puberty.. it's fun to inflate the breasts, giving them a great feel, but they will deflate in a couple hrs..
Now, there are the techniques that cause lactation, check those out.. without meds and alot of patience, you can start lactating! This will cause oxytocin to be released into your system, better than euphoria! But along with this, you will increase your milk glands making your breasts look bigger for a few days as long as you don't stop the routine.. once you stop, it takes weeks sometimes to start back up.. this actually works, but you breast will look funny because they are gland increased but no fat to round them out..
There was a show on the science channel I believe about the ways to increase your breasts, it was rather informative.. it was about cis women, but only difference is they already went through puberty so hrt is out for them.. in their case it's either a breast augmentation or bra stuffing!
Have fun with your suction toys, but they are just that unfortunately.. alot of studies have been done through the years in multiple countries, all say the same sadly.. just please don't apply too much vaccum to where you burst vessels and cause scaring you may regret once you may want hrt.. you can if you apply a vacuum alot, stretch the skin. With no fat behind it, you just end up with saggy boobs if you ever achieve.. without hrt, fat will never deposit behind the breast, so how do you really expect them to grow?
Here is one last thought:) these studies were done on older cis females.. but what if you applied suction to expand the skin so the fat can develope back there easier when on hrt? Just think that on hrt, we feel pressure because of fat buildup and tight skin on the front? Here is something you should look into:) I would love to see the results on that one.. maybe you can prove that to be true and help tgs grow better breasts?
I have the mentioned pump and others, and different size breast molds for doing this.. I just never see it viable todo.. I do like doing lactation and my meds help start that process.. for me, it's the oxytocin release I enjoy..
Ok, hope this helps.. feel free to prove me wrong, but please exhibit studies to do so.. I love science and statistics and would love to be wrong.. if I knew the above idea would work, I'd be pumping away!
Oh, if you do try the milk thing, you will get what looks like you art for a few days.. but after a while it comes out as a sweet smelling liquid.. to me it's like almond milk w cream in it.. yea some of you are disgusted by now, but there was a couple, one was tg who shared breastfeeding responsibilities with their newborn.. look it up, some may be repulsed, but it's only natural for females, last I checked, our breasts are the same as a cis female after our female puberty... laters;)
