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 | Preliminary human | Preliminary human |
| 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 thymus-extract peptide preparation from the Russian "bioregulator" tradition, marketed online as an immune-restoring, anti-aging compound. It has more genuine clinical history than most research peptides — including a Soviet-era approval that still stands in Russia — but the human…
Thymosin Alpha-1
Thymosin Alpha-1 (thymalfasin, sold abroad as Zadaxin) is one of the more genuinely studied peptides on the market. That doesn't mean it does what wellness clinics claim it does.
