Optimizing thyroid levels for longer lifespan?

Did you copy this from a link or did you type all this yourself? If there’s a link, I’d be interested in checking it out

These are my thoughts @LukeMV based on a synthesis of reading over the years. You will find many sources related to this discussion. Here are a couple of links I have handy. With a little searching, you will find others even more on point.

Ah ok. That’s cool you tried injecting TRH! Good to hear your symptoms are much better.
That’s a tough call about the free t3 levels and energy.

If you have never tried ADHD medication (or other reuptake inhibitors) it’s something to try one day.
As there are 3 popular reuptake classes (dopamine, noradrenaline, serotonin) so some people stack various products. Some products have 2 in 1 etc.
Usually serotonin paird with dopamine or noradrenline. Some people do all 3.

I don’t believe Wellbutrin is an amphetamine. A lot of online pharmacies carry it.
Some people on this forum use it with good reviews. It appears to be a bit similar modafinil but more of a energy/motivation feel. Kinda like a more narrow focus (intense concentration).

Don’t know if you’ve read about Nandrolone use and it’s effect on neurotransmitters, but there are some interesting articles on animals/rodents. I’ve seen articles saying it can increase or decrease certain chemicals. Not sure what to think on it however.
