Thymus polypeptide complex.
Thymalin is a polypeptide extract from bovine thymus developed in the USSR in the 1970s. It belongs to the same Russian peptide-bioregulator research tradition as Khavinson's later work, predating the synthetic short-peptide era. Supplied as research-grade material with 3rd-party HPLC verification and full Certificate of Analysis per lot.

The preparation is described in the literature as modulating T-cell maturation and differentiation. Reported effects include restoration of T-cell populations in thymectomized or immunodeficient animal models and modulation of cytokine profiles in inflammation studies.
Used clinically in Russia and some Eastern European countries for immune modulation. Not FDA-approved. The extract nature of the preparation means lot-to-lot composition variation is an inherent consideration.
The above summarizes published research literature. This is not medical advice, a protocol, or a recommendation for use. This compound is supplied for laboratory research only.
Thymalin is a complex mixture, not a single defined compound.
The full structural data and release specifications are in the Compound Profile section above. Every lot ships with an independently verified Certificate of Analysis.
Each lot is independently verified by a 3rd-party analytical laboratory (STERIS Labs, Alcami Analytical, or equivalent) before release. Release specification is HPLC purity ≥ 99.5% (typical > 99.8%), mass spectrometry identity match within ±0.5 Da, water content < 5.0% Karl Fischer, and endotoxin < 0.25 EU/mL by LAL (USP <85>).

All compounds ship at ambient temperature in discreet, tamper-evident packaging. Lyophilized peptide powder is stable at room temperature for typical transit windows, which is why research-grade vendors ship this way. Tracked; signature not required.
Store unopened lyophilized product at 2–8°C protected from light. Once reconstituted, most peptides are stable at 2–8°C for approximately 28 days (compound-dependent).

All PeptideBros compounds are sold strictly as chemical reference materials for in-vitro laboratory research. They are not for human consumption.
HPLC-verified. Mass-spec confirmed. Ambient-stable transit. The paperwork other vendors hope you never ask for.
