What are the most common mistakes with Thymalin?
The most common Thymalin mistakes are confusing Thymalin with Thymosin Alpha-1, different molecules, different evidence base; running continuously instead of pulse protocols; expecting Western RCT-grade evidence, this is a Russian clinical peptide with limited English-language trial data. Most issues people run into come down to protocol and expectations, not the compound itself. Going in informed matters here because human evidence for Thymalin is limited.
Common Thymalin mistakes
- Confusing Thymalin with Thymosin Alpha-1, different molecules, different evidence base
- Running continuously instead of pulse protocols
- Expecting Western RCT-grade evidence, this is a Russian clinical peptide with limited English-language trial data
Bloodwork worth tracking
- CBC if running multi-quarter cycles
- CD4 / CD8 ratio if you have access
