Protein intake and carb: protein ratio for maximal muscle gain?

[GreekDemiGod]

I’ve been reading recently from bioenergetic sources and accounts on how protein is anti-thyroid, anti-metabolic (especially cysteine, methionine) and will lower the metabolism. Also how Broda Barnes noticed that protein “consumes” more thyroid hormone.

I do resistance training 3-4 times per week. I am 82 kg (180 lbs) and average around 100g of protein per day, but my recovery and strength suffers. I thought that was from being hypothyroid, but whenever I bump my protein intake to 130-150g, I gain more strength, recover better in the gym. What gives?
They say that 1.6g of protein per kg of bodyweight will maximise muscle gain.

Would it be bad to bump up my protein intake regularly to 130-150g, considering I eat 300-450g of carbs/ day, so I get a carb: protein ratio of at least 2:1?
I want to mitigate the negative effects of high-ish protein intake.

Is 130-150g of protein that much, harmful?

@GreekDemiGod Jay Feldman and Mike fave recommend a good amount of protein for clients around .6 to .8 grams per pound with a good source of glycine. It’s reasonable to me
