Thymalin vs Thymosin Alpha-1
Both are immune peptide compounds. Here's how they line up on the evidence — graded the same way.
| Thymalin | Thymosin Alpha-1 | |
|---|---|---|
| Evidence | 5/10 | 8/10 |
| Class | Immune peptide | Immune peptide |
| Summary | A Russian thymus-extract peptide preparation studied for immune modulation; the human data is real but thin, small, mostly non-blinded, from one research lineage, and unreplicated outside Russia. | A thymus-derived immune-modulating peptide with real but mixed human trial data: helpful in hepatitis B, but negative in the largest sepsis trial. |

Thymalin
Thymalin is a peptide preparation made from thymus tissue, and it comes out of an old Russian "bioregulator" research tradition. Online, it's sold as something that restores your immune system and slows aging. It actually has more real clinical history than most research peptides — including a…
Thymosin Alpha-1
Thymosin Alpha-1 (also called thymalfasin, and sold overseas as Zadaxin) is one of the more genuinely studied peptides you'll find for sale. But being well-studied doesn't mean it does everything wellness clinics say it does.
