How to Use Thymulin
Complete guide to Thymulin dosing, administration, timing, and protocol recommendations.
Quick Overview
Thymulin is a tiny nine-amino-acid hormone made by the epithelial cells of the thymus, first described in the 1970s as facteur thymique serique (FTS). It only works when bound to one zinc atom, which makes it an oddly neat marker of zinc status. It plays a part in training T cells, and animal work suggests anti-inflammatory and pain-reducing effects. It is sold online for immune support and hair loss, but there are no modern human trials of giving it, and the hair claims rest on lab dishes and a sponsor-linked cosmetic study.
Dosing Guidelines
Common Dose
No established dose
Frequency
Unknown
Dose Range
Unknown
Note: There is no human trial dose for thymulin as a treatment, and we are not going to invent one. Anything sold with a dosing chart is guesswork. Thymulin needs zinc to work, so low zinc status is the more obvious thing to check and correct.
Administration Method
Sold for subcutaneous injection or topical use; neither route has been tested in controlled human trials
Best Time to Take
No evidence-based timing
No human pharmacokinetic or dosing studies exist, so there is no basis for a preferred time of day.
Protocol Duration
Unknown; no human trials to guide duration
Possible Side Effects
Not everyone experiences these. Individual responses vary.
- •No human safety data for administered thymulin
- •Injection site reactions (expected with any injected peptide)
- •Theoretical immune effects in people with autoimmune disease
- •Unknown purity and contamination risk in unregulated products
- •Topical products: possible scalp irritation
