At a Glance
| Dimension | Thymosin Alpha-1 | LL-37 |
|---|---|---|
| Immune System Target | Adaptive immunity (T-cells) | Innate immunity (antimicrobial) |
| Clinical Evidence | Strong (approved in some countries) | Preclinical + limited human |
| Primary Use | Immune modulation, chronic infections | Antimicrobial, wound healing |
Thymosin Alpha-1 Deep Dive
Thymosin Alpha-1 (Zadaxin) is approved in several countries for hepatitis B, hepatitis C, and as an immune modulator. It enhances T-cell function and has been studied in cancer, HIV, and sepsis. It has the strongest clinical evidence of any immune peptide.
How to Choose
Choose Thymosin Alpha-1 if…
- •Adaptive immune modulation is the goal
- •You want the immune peptide with the strongest clinical evidence
- •Chronic viral infections or immune deficiency are concerns
Choose LL-37 if…
- •Antimicrobial effects and innate immunity are the focus
- •Wound healing or biofilm-related infections are concerns
- •You want a peptide with direct antimicrobial activity
Consider Both If…
Thymosin Alpha-1 + LL-37 may be combined for comprehensive immune support addressing both adaptive and innate immunity.

BPC-157 vs TB-500
BPC-157 excels at localized tendon, ligament, and gut healing. TB-500 is better for systemic muscle recovery and widespread inflammation.
Semaglutide vs Tirzepatide
Tirzepatide produces greater average weight loss in clinical trials. Semaglutide has a longer post-market safety record. Both are excellent options.
Ipamorelin vs CJC-1295
Ipamorelin and CJC-1295 work through complementary mechanisms and are almost always used together rather than as alternatives.
Ozempic vs Wegovy
Ozempic and Wegovy both contain Semaglutide. The difference is FDA indication and maximum dose — Wegovy is approved for weight management at higher doses.
Mounjaro vs Zepbound
Mounjaro and Zepbound both contain Tirzepatide. Mounjaro is approved for Type 2 diabetes; Zepbound for obesity. The active ingredient is identical.
Selank vs Semax
Selank is primarily anxiolytic — it reduces anxiety and improves mood. Semax is primarily a cognitive enhancer — it boosts focus, memory, and BDNF. They are frequently combined.
