Here’s a list shared by Gpo last year:
Jing has been upgraded twice since then, including a negentropic version (on Teespring).
Tonic no. 31 (Gumroad)
Induced Mots-C Production
Ambrosia (NFT)
Exalted State (NFT)
Mstate Collection (some of them are anti-aging-related)
etc.
Antioxidants and most of the organ fields labeled as “regeneration, rejuvenation, restoration…” contribute as well.
Edit: remembered this quote by _OM afterward:
Even Plasma Light alone would make a big difference on its own. Still a very powerful one and the base of all the other fields released ever since.
