I have been using about 50 grams a day of 1 Fast 400 BCAA's and have been having huge sleep problems. Only able to sleep about a half hour at a time if that. Has anyone else ever had the same problems. I don't know if this is true or not but a friend told me that caffine is mixed with BCAA's at times to .

I seriously doubt it has anything to do with the BCAA's. I would look at the rest of your diet and supplements for a possible cause.

Ive been taking bulk bcaas for a while now and have never had sleep problems...there is nothing in it that should keep you up

Thanks for the responses. Just trying to eliminate things.

slow down on the bcaa's too much can cause a dopamine imbalance, could be the source of your problems.

Holy fuck, 50 grams a day???? Are you more than 250lbs? Wouldn't see the need to consume more than 25g/day. At 190lbs I stick around 15-20 g / day at most. If I take too much at once I feel dogged down.

I do about 40g a day. 20pre and 20 post. But I can't imagine it would effect your sleep

I weigh 285 lbs. When I upped the dose to 50g I feel great all day.

Per 5 grams: 2.5g L-Leucine
1.25g L-Isoleucine
1.25g L-Valine
