Why the difference in reviews on Reddit vs. Amazon for MicroMag?

Replying to Happy-Walk3489 · Hey, I saw one of your posts on P21 from 12 years ago when you were taking it. Are you still taking it and what did you notice?

Yeah, we were the first company to ever release P21. It's a really cool peptide. I ever developed entirely new peptides based on what we learned from it, like Adamax. That's my peptide that I created and named. I also made other ones we never released that are even better. No, I…

Replying to P21throwaway · P21?

We were the first to bring out P21. However, I made my own new peptide that I named CEN-1. P21 was what inspired me, though.

Right? Andrographis a really cool one that I take every day. It doesn't get the attention it deserves.

Replying to Chargers95 · CNTF is the growth factor key in the survival of new neurons, correct? Edit: it’d be interesting if you guys could find a natural product that could increase CNTF similarly to P21

Yes, CNTF is a crucial for the growth of astroglia. It's one of the critical neurotrophic factors in the brain. Many people focus on BDNF and NGF, but CNTF and GDNF are both crucial, too.

The peptide P21 does, but I can't think of other natural supplements that do.

That doesn't look like a reliable vendor. There are no 3rd party labs giving them COAs for those products. They are just lying and hoping people won't call them out about it. Ask them for one of the 3rd party COAs, and send it over to me. Peptide 6C is just a shittier version of…

Replying to RX_btw · /u/misteryouaresodumb any experience here? or know of any stories from other people over the years

I have not noticed any hair changes from P21. The people that have had that effect usually see it from Semax, which hits BDNF. However, it is a rare effect from what I have seen.

We created phenylpiracetam hydrazide back in the Ceretropic days. I found the research on piracetam hydrazide, and figured why not add a phenyl group? So we contracted a lab to make it for us. N-acetyl semax and N-acetyl semax amidate were us, too. All the acetylated and amidated…

Ohh man, that's a tough one. Maybe lion's mane, 7,8-DHF, polygala, and surprisingly berberine. Then you are hitting NGF, BDNF, and sigma-1. The other one to target would be CNTF. I'd have to think about what supplement would be best for that. The best synthetic for that is the P2…
