I find I can do the 100g with a good serving of organic meat or wild fish at lunch and dinner, with a mix of nuts, duck eggs, sheep cheese and yogurt, and lentils throughout the rest of the day.
To go above 100g really seems to need supplementing. Most protein powders are problematic, either with toxins, allergens, or the wrong ratio of aminos, so I've found supplementing aminos my body needs, either through oral capsules or powder is best. There are 3 companies I know of that will customize aminos, and the cost vs doing each separately is comparable.
Regarding the ratios, one common amino acid predominant in most powders is arginine, which is not good with a chronic herpes family viral infection (EBV, CMV, etc.) And many of us need lysine, glycine, cysteine, and tyrosine, which are in short supply in most commercial powders...
It just takes finding what you need and developing habits to get you there...
