Thymosin Alpha-1 is Certified Aminos' research listing for a 28-amino-acid peptide derived from prothymosin alpha, studied for its influence on T-cell function and cytokine signaling. Distinct from Thymosin Beta-4 and the TB-500 fragment, which belong to a separate thymosin family. Available in 10mg for laboratory research use only.
HPLC certified
Independent analysis
Highest standard
Full traceability
Each order ships as a Thymosin Alpha-1 research peptide in a 10mg vial, manufactured for laboratory use only.
| Product Name | Thymosin Alpha-1 |
|---|---|
| Sequence Length | 28 amino acids, derived from prothymosin alpha |
| Related Compound Distinction | Thymosin Alpha-1 is unrelated in sequence to Thymosin Beta-4 (a separate 43-amino-acid peptide) or the TB-500 fragment derived from it; the three share only the "thymosin" name |
| CAS Number / Molecular Weight | Not established for this specific listing |
| Purity | Not independently verified — no batch-specific COA is currently published |
| Identity | Not independently confirmed by mass spectrometry or an equivalent method |
| Available Size | 10 mg |
| Intended Use | Laboratory research only (RUO) |
When your order arrives, match the lot number printed on the vial to the lot number on the COA before beginning any work. Until a batch-specific COA is published for this product, treat any purity or identity figure shown elsewhere on this listing as a supplier claim, not an independently verified result.

A 2025 Phase 3 trial of 1,106 sepsis patients found no mortality benefit from Thymosin Alpha-1, overturning earlier signals. What the evidence actually shows.

HCG and LH bind the exact same receptor — yet research shows they send measurably different signals once they do. Here's what's actually established about HCG's structure, mechanism, and the FDA's position on HCG weight-loss claims.

No peer-reviewed human study of IGF-1 LR3 exists — a 2026 literature review placed it in its lowest evidence tier. Here's what the cell and animal research actually shows, and where it stops.
