There are many ways to get protein from veg diet..
soy protein? lol, it'll fuck your hormone profile beyond any reasons, soya chunks used to be pig fodder before suddenly corpos thought of projecting it as a 'vejj protein source'
even whey protein things aren't just cutting it as protein itself is a group of things and milk/whey stuff barely makes half of that group of essential proteins
besides, meat based diet isn't favoured for strength and all jus for being a source of le

rotein, it also contains lots of essential minerals and amino acids in single package, some of them only available through that kind of diets - things like l-carnitine, l-arginine etc which boosts muscle performance are outcome of these essential amino acids when consumed
lastly, you can enhance t and dht levels via diet planning and strength training, cardio etc exercising but benefitting from it all itself is another thing
you may have best of diets including red meat and all; but if you don't have proper androgen receptor profiles (in terms of intensity and density both) in your body, you wouldn't be able to benefit much from available testosterone and dihydrotestosterone at all; so it's also partially genes
