I want to mix up my own version of an energy drink containing:

BCAAs - flavored
Piracetam
Tyrosine / N-Acetyl-Tyrosine
A little Theanine


I think all these things would be fine to sit in water for a couple days if I mixed a couple days worth up, but am looking for confirmation..thx.

Yeah, watch out though...the taste is, shall we say, powerful.

Imagine wee mixed with battery acid...worse than that.

I have to cap it.

Indeed it is quite repulsive although there are worse things, in fact you can make horrible tasting mixes like piracetam+b50 powder, piracetam+sulbutiamine, but there is a good thing about piracetam the taste does not last, once you have downed it the taste is gone, other racetams like anir or expecially nefir are the oposite, the taste refuses to go away.
But it can be partly masked, orange juice masks it quite a bit, nac too, and orange juice+nac even if the experience is less than pleasurable makes it tolerable.

The taste is under control...atleast to a reasonable measure...

16oz water
3g Piracetam
1g Tyrosine
3/4 scoop of Lemon Xtend
1/2 scoop Mango Excell

I drink 1/4 of the bottle a few times during the day at work...been about 10 days since Im back on Piracetam after not using it for months and months and starting to feel a little more dialed in again.
