Sorry to hear that you have gotten this side effect. I did some digging and found some interesting tidbits.
Pharmacokinetics of huperzine A following oral administration to human volunteers
- Huperzine A acts as a reversible inhibitor of AChE and antagonist of the NMDA receptor.
- It is also involved in regulation of oxidative stress and enhances level of antioxidants in the peripheral organs and central nervous system
It seems that Huperzine A has a rapid onset in plasma of about 5-10 minutes and a half time of 12 hours.
This is my 4th day report regarding Huperzine A and I must say that I am kind impressed by a few things with regards to it.
- First, I must say that it has had a positive mood effect on me in almost an antidepressant way.
- Second, it feels as my mind is clearer, less brain fog.
- Third, I do find my mind having clearer images of the past when thinking about it.
- Fourth, vivid dreams, I mean really vivid dreams. I would have to go back to childhood to find as vivid dreams as I have now. They are also mostly pleasant.
- Fifth, in regards to tinnitus I would say that it is in many ways less intrusive. I wouldn't say that the tinnitus itself is much lower but it feels thinner.
In regards to placebo I would say that I have tried so many different solutions to the tinnitus problem that my placebo reaction is mostly non existent. There is one uncontrolled thing here and that is that I do use Lenire from time to time since I find it does give me some calm after a few days of use. I stopped that a week before starting with Huperzine A and it could have some kind of effect.
I will try the combo of Lenire + Huperzine A to see if it makes a difference in anything in the near future.
On top of this I will cycle off Huperzine A after 20 days and stay off for two weeks to see if a change is noticeable.
Also as a side note, I finally got to visit my mom since she got the final Pfizer jab three weeks ago. I slept in the room where I spent 8 months with tinnitus and hyperacusis hell and it is incredible to feel the different state I am in now compared to then. How much less tinnitus I have and how my hyperacusis tolerance has gone from 42 dB to 75 dB.
