Summary
A Reddit user whose gut was much helped by the peptide KPV on a very low 50 mcg dose, though higher doses brought joint pain flares, so they stopped it and kept on with other peptides. Thymosin alpha-1 at 0.15 mg twice daily eased their autoimmune arthritis joint pain and left them feeling mentally clearer, at a dose limited by what they could afford.

Their words about each treatment
- KPV · Worse
It did wonders for my gut, but I think it has worse side effects compared to other peptides. ... it really really helped reflux
In context ↗ - bpc · Not said
Gonna stop it and continue with bpc and ghk
In context ↗ - TA1 · Helped
TA1 daily (0.15mg 2x daily) has been helping my autoimmune arthritis (AS) symptoms, and has lifted something (mentally) to where I feel clearer and more confident.
In context ↗ - Allevia (allegra) (fexofenadine) · Worse
Allevia (allegra) (fexofenadine) was most potent for me, but reliably gave me horrible reflux and weird feelings. I wish I could tolerate it.
In context ↗ - Ceterizine · Helped
Ceterizine isnt doing the job enough
