  • Preworkout Toxicology Study

  • the_gainz   •   Sun, Feb 10th, '19 05:56   •   15 replies, 271 views

Apparently an amino acid called l-norvaline (suppresses argininase which shuts off nitric oxide production - supposed to increase blood flow and pumps) can be toxic to cells. Not sure exactly how the study was conducted. I’m sure if you dump enough of anything on cells, it’s toxic. I know there’s none of this in my black coffee I drink pre-workout. Just wanted to post and see what everyone’s thoughts were. Scary headline to get attention or legitimate study?

A lot of people like to drink some coffee or get a little caffeine in them some how before working out. I have bad anxiety to the point where I can't even drink a cup of coffee of take any caffeine. I can't take any kind of stimulant pwo and it really sucks! Years ago, I used to take a pwo with caffeine and it really did help a lot. I wish I could just drink a cup of coffee or something.

I like pre workouts. I love them actually. I work crazy hours and I need it. Interesting post, thank you for the share.

I don’t care about pre workouts, much rather prefer nice cup of coffee as my pre workout ritual.

Hate to admit it but there was a time when I thought I just had to have a pwo drink to w/o. Since I joined eroids though I've dropped that crap like the bad habit it is and haven't looked back. All I take pwo now is black coffee, protein with bcaa, and a nice homemade carb shake with oats, bananas, blueberries, two cups fat free/lactose free milk. Change out the fruit sometimes depending on price/availability.

If I'm doing anything pwo besides that it'll be aqua.

Yeah man, just a natural cup of coffee is all I ever need. That being said who knows what the hell is in most of these anabolics we use or the materials they’re made from...

Most PWO supps. are just high dosed caffeine with whatever the newest thing out that they can put in their propriety blend. And true with supp. companies you never know what is really in it.
Companies have put stimulant drugs in their PWO to make them work better and get the word out that this is the newest and best PWO.

I stick with the good old ECA stack. Which i purchase at the store individually so i know exactly what i'm taking.
I've yet to develop a tolerance and it still works. With PWO people are always talking about changing brands every couple of months because they get use to it.

I never bought into the whole pre work out craziness. Your black coffee is full proof and so is some caffeine and arginine tabs and cost about 1/4 as much as these goofy powders
