More research isn't a bad thing, but this really isn't news. If you're a nerd who's into lifting you'd already know that soy protein is a top tier source of all the important amino acids for muscle gain. And it's cheaper than whey.
It's also not very popular because the manosphere tells men that consuming it will feminize them. Yes, really. They took the "soy boy" thing very literally and ran with it off the deep end.
People continue parroting this soy estrogen myth even years after it's been debunked too, it's annoying as hell. The phytoestrogen in question is more of an anti-estrogen and may be protective against excess estrogen.
If soy actually caused boob growth, the supplement industry would be all over that.
bigger issue with these powders and shit (least in the US) is that damn near non-existent food/drug safety oversight means that your probably getting dosed with a bunch of lead or some other contaminate...
I remember about a decade ago talking about tofu recipes with a colleague who lifted and ate a protein heavy diet.
An older colleague heard us and warned us that eating tofu would cause you to have a surplus of estrogen and make you more feminine.
He was telling this to a guy built like a brick shithouse who had eaten tons of soy protein for the better part of a decade.
It's that same old thing, something different comes along and some people just have to parrot anything that goes against that thing, even if it's complete and utter horseshit
As a human survival trait we need to find a way to shut down misinformation. Knowledge is our path to survival as an animal. Like ants have teamwork and building, wildebeest have speed, plants photosynthesise, humans learn.
By creating and spreading misinformation you're chipping away at pretty much the only thing that keeps us in existence.
Bit of a broad-strokes extreme takeaway from your comment there, but it got to me.
That's fine.
I'm a 40 year-old man and I'll still post up next to a group of these Gen-Z pansies and put up 300 pounds on the bench with my gnarled, old man physique.
Oh my god, everyone look at how tough this tough guy is!
How to tell someone you're jealous without saying it out loud. Cheers, friend.
Jealous of what exactly? Lol. Edit: Hahaha, holy fuck guys, read this guy's bio if you want a good laugh.
My bad dude, I thought you were serious. Poes law in action.
Oh I know right bro, right? Bro?
I recently decided to restart my routine after 8+ years of dickin' around and this is blowing my mind right now. What else has changed? Is creatine and NO2 still a thing?
Creatine is still very much a thing, but I think everyone actually knows what it is and what it does and it's not treated as a magic bullet any more.
Mainly what seems to have changed is that steroids and TRT have exploded in popularity, and a scary number of under 18s are doing it.
Apart from that I couldn't tell you, it's all happening on Insta and TikTok now and I don't participate.
I'm a nerd and into lifting, but I took a pause for oh very many years, so I'm currently still emptying my 2.something kilogram tub of Optimum Nutrition whey protein, which tastes decent enough. Do you have a recommendation on decent tasting soy protein, especially something available in Europe?
I pretty much look like a bear so it's going to be very difficult to feminize me lol
Meat and dairy contains hormones that increase estrogen and reduce testosterone, not plants.
That may be, I was just saying I'm not particularly concerned about it anyway.
Yeah I know, that's why T levels in the USA has dropped by 20% in the last 20 years and obesity is rapidly increasing.
Pretty sure obesity is increasing because people are sedentary and eat like shit.
Testosterone is known to go down in obese people so I think you have your cause and effect reversed there.
It does have some protoestrogens but to me that is a positive because I want to look fem. Most men have low estrogen and it makes them uglier and psychotic. The only time estrogen really feminizes you beyond giving you a better body shape and slightly healthier skin and stuff, is when you are taking a high amount of it.
Most men have too low of estrogen and this causes mental issues, depression, it gives them a lot of fat around their stomach while being lanky everywhere else. It causes all kinds of weird little issues.
Perhaps you mean phytoestrogen? Another commenter suggested that the applicable phytoestrogen found in soy may actually be protective against excess estrogen.
Last time I checked what's available on my grocery store shelf, the whey protein was still the cheapest by unit.
Where I live grocery stores are a terrible example, all the plant proteins are jacked up in price with marketing about how it's organic and vegan and will cure cancer yada yada. And then the wheys they sell are blends with low actual protein content and/or poor aminos.
I buy my protein from a bulk supplements supplier, and soy is 75% of the cost of the cheapest whey, gram for gram of actual protein content.
