High dose GABA during the day as well

[jp_x_type]

Am playing around with gaba at the moment. Have used it on an off for years but usually in high pre bed doses, which led to ridiculously deep sleep (and im one who sleeps for no more than 4 hours usually, as im hyper) and good recomp/definition.

Its 3pm and i just took a gram of gaba powder. I need to point out i eat once daily, at around 9-10:30pm (yeah i love taking my time eating 3k and over at once). So this was done on an empty stomach as it should be.

Well this stuff taken now has stimulated me more thAn 200mg caffeine. Wtf? I even have some jitters lol

Any expereinces with high dose gaba taken during the day? Results of doing this? Aims? Maybe taken pre workout?

Also, what do you guys like combining gaba with?

I plan to take an extra 3g before bed tonight and will continue doing so , but what i did today when i took it during the day seems to have made me wonder whether its the same gaba i remember!

3-5g GABA 30 min pre-workout has shown to increase Growth Hormone by 400% during training and 200% after training (think those were the numbers but it was a significant increase).

Been a bit curios about GABA my self but some says it lowers prolactin and raise GH other says it increase prolactin and lowers test.
Anyone know the latest research on GABA?

I'm not all that impressed...

There are a number of GH isoforms (100 or so), and GABA has been shown to increase (in vivo after oral administration) immunoreactive growth hormone (irGH) and immunofunctional growth hormone (ifGH) respectively.

The combination of GABA with physical activity did reduce the maximum time to spike (30min vs 75min at rest) and higher peak values. However, it is unclear whether irGH and ifGH have any of the same benefits of the most common form of GH we are accustomed to speaking about.

My guess is that neither have much implication on muscle growth or fat reduction. Additionally, even if they did, the duration of the spike is too short lived to have any lasting effects.

Just my 2 cents playing devils advocate. Keep us appraised of your experiment OP.
