Caffeine increases progesterone, pregnenolone, T, DHT, allopreg, 5AR in brain

[TubZy]

Hi,

I would like to share a pretty cool study with you regarding caffeine, 5AR, DHT, T, allopreg, progesterone and pregnenolone all in the brain.

Caffeine-induced increases in the brain and plasma concentrations of neuroactive steroids in the rat. - PubMed - NCBI


From the full study:

"...The injection of caffeine (25 to 100 mg/kg IP) resulted in dose-dependent increases in the cerebral cortical concentrations of pregnenolone, progesterone, and allopregnanolone that were apparent after 30 min (Fig. 1). The effects of caffeine on the cortical concentrations of these three steroids were already significant (72, 90, and 47%, respectively) at the dose of 25 mg/kg, with the greatest observed effects (188, 388, and 71%, respectively) apparent at the dose of 100 mg/kg."

So, at the highest dose, which translates to about 1,200mg of caffeine for a human (single/bolus dose), levels of pregnenolone almost tripled, levels of progesterone almost quadrupled, and allopregnanolone almost doubled.

The dose is big but you can work your way up higher or even to lower and use things like GABA agonists like niacinamide and herbs or even aspirin to counteract any of the stress response from the caffeine along with being properly fueled. I originally came across this because I was using topical caffeine on my head and face for hair and skin benefits but I also felt much better after applying it even mentally.

I didn't even know there was such a thing as topical caffeine

There isn't. I make my own with niacinamide and aspirin in a water and alcohol solution (or a product called solban, but I make mine much more potent). Makes my skin and hair very nice.

I want you to learn and not take my word for it

Why thank you.....that's nice of you....lol.

But I learn simply by listening to the things people say. If it doesn't make sense to me, then I will go and seek out research material. But for every single thing, it's not necessary.

I know you're a smart dude. So when you post something, I learn just by reading the post, depending upon what it is and if it's not something that I already know.

If we were to get into some type of debate, then I could see where it may be helpful, but for every day run of the mill convo, there is no need my friend. Most of the time I don't need back up references.

I'm a quick study. If I hear something that makes sense to me, intuitively I know that it's true, or correct, or I can see how it would work in my head.

Do you tend to take caffeine pills or drink coffee to get so much caffeine?

This comes as no surprise to me. I always feel my best after taking down my coffee and this was always the case during my whole recovery. I DO NOT miss my coffee, EVER.

Same. Even though it doesn't feel great on my gut

Yeah I normally hit the shitter after my morning coffee, but hey, it's a great feeling. I've noticed that if I take my coffee right after taking hormones on cycle, it's almost a euphoric feeling, very similar to dosing coffee with herbs.
