^^ Please refrain from giving advice even if you preface it with how you don’t know much. You include a caffeine based pre-workout even though it really corresponds to none of the OP’s goals. You then follow it up by saying BCAA’s are negligible even though most on this site would put them at the top of the list.
To the OP, your focus should be on whole foods. Outside of protein, I would say creatine, BCAA’s, fish oil, and a multi vitamin/mineral support (dependent on how your diet looks) would all be wise choices if you’re looking for size and performance improvements. As far as a libido boost, you can look at simple products such as Tribulus, Maca or Horny Goat Weed or a product that combines several ingredients such as Alpha Male that is sold on this site. Best of luck in your goals.

i recommended normal coffee/caffeine supplement because at the end of the day it gives you the boost required to have a better workout especially if he is caffeine sensitive and coffee is cheap … and if you read he states what would help in ‘muscle mass’ and ‘performance’ so caffeine is actually a valid recommendation… i never put down the good effect of bcaa’s i clearly stated that just adding so many supplement in at once wouldnt give you a clear indication of which supplements are working for you and he already is supplementing on glutamine … and besides that if he is following your advice of eating whole food he would get a substantial amount of bcaas from whey and other quality proteins just like DoubleDuce stated
