[educational] An alpha-thymosin (immune-specific), distinct from the beta-thymosins (TB-500/TB4) which drive cellular structure/repair — both originate from the thymus but act very differently. — TB500 deep dive

Anecdotes
[anecdote] Regarded as the best immune-modulator — dial down autoimmune overactivity (lupus, RA, celiac, type-1 diabetes) or dial up a lagging immune system (long COVID). — Koniver 01:41
[anecdote] Thymic-family hormone (≥21 aa) — ‘jet fuel for T-cells’ (development + proper pathogen targeting). FDA-approved historically as Zadaxin (thymus-deficient children); abroad an adjuvant for hepatitis B/C and some cancers (Goldstein-lab ‘fraction 5’). — Bakri 01:35–01:36
[educational] Ranked #3 longevity — counters immunosenescence (dendritic TLR activation + IDO immune-tolerance). 11,000+ patients, approved in 35+ countries; severe-COVID mortality 30%→11%; NSCLC −45% death risk. Gap: evidence is in the immunocompromised, not healthy-aging prevention. Consider when CD4:CD8 <1 (common past 60). — Longevity Top-5
Physician protocols
[protocol] ~5,000 mcg/day, sometimes IV. [note] Removed by FDA. — Koniver 01:42
[protocol] Bakri uses ~2.5 mg twice weekly as a travel/ward prophylactic (reports staying well across a hospital season — anecdote). — Bakri 01:37
