Not a source, but here’s the cheat sheet info for Thymulin (which some call Thymalin, essentially animal derived vs synthetic).
Thymalin/Thimogen Longevity, Immune system • Treatment of immune disorders
• An anti-aging agent
• Improves respiratory and cardiovascular health
• Enhanced anti-inflammatory properties
• Potential anti-tumor activity Treatment length: no longer if 10 days if taken daily, no longer than 10 weeks if taken weekly. Preferably no more than 100 mg in a cycle. Can do two cycles a year.
Note: Thymalin is an extract of Thymogen. 10 mg of Thymalin = 100 mcg of Thymogen.
30 min before Thymalin take 30 mg of zinc
IM (some do SQ):
• For treating immune disorders: 5-20 mg daily for 3-10 days (manufacturer’s instructions)
• For anti-aging effects: 2-5 mg daily (World of Peptides)
• For anti-aging effects: 5-10 mg daily (manufacturer’s instructions, Jay Campbell)
• For anti-aging effects:10 mg once or twice a week (Reddit)
Thymalin is often stacked with Epithalon:
IM (some do SQ):
• 5 mg thymalin and 5 mg epithalamin daily for 20 days, repeating every 6 months (Jay Campbell) Epitalon (Epithalon, Epithalamin) LINK
• Thymalin is an extract of Thymogen and is more concentrated, so need to take 100 mcg of Thymogen instead of 10 mg Thymalin
• Similar to Epithalamin vs Epitalon
