One of these is a molecule and the other is a preparation, and that single fact governs what either certificate can say. Thymosin alpha-1 is a defined 28-residue synthetic peptide, N-acetylated, C129H215N33O55 at 3,108.3, CAS 62304-98-7. It has an exact calculated mass, so its certificate reports a measured mass against that figure and a purity as the area percentage of one chromatographic peak. Thymalin is a calf thymus-derived polypeptide preparation, a mixture of low-molecular-weight peptides running from roughly 600 to 6,000 daltons, CAS 63958-90-7, and there is no single molecule in the vial to weigh. Its certificate carries no calculated mass and no single-peak purity; it is read on the profile and the content of the preparation as a whole. A buyer setting one purity figure beside the other is comparing two different measurements, not two grades of the same thing. Thymosin alpha-1 is stocked in three strengths, thymalin in one.

Questions
Which is cheaper per mg, Thymalin or Thymosin Alpha-1?
Thymalin, at $0.924 per mg for its best-priced strength (TY10) against $2.05 per mg for Thymosin Alpha-1 (TA10), 55 percent less. Compare at the vial size you will actually use; the gap changes with strength.
Which comes in more strengths, Thymalin or Thymosin Alpha-1?
Thymosin Alpha-1, with 3 against 1. Every strength is a separate line with its own code, price and stock state.
Can Thymalin and Thymosin Alpha-1 go in one order?
Yes. Any lines can share an order; the minimum is $300 of goods per order, or $100 on a first order, and one sealed box of ten per line. Lines on the shelf ship in 1 to 2 business days; made-to-order lines follow in about two weeks, at no extra freight.
Are Thymalin and Thymosin Alpha-1 tested to the same specification?
Yes: purity not less than 98.0 percent by RP-HPLC, identity by mass, water content, net content within 5 percent of label, and a retest date, with a certificate of analysis per batch. What differs is what each certificate has to look for, which is set by the molecule and described on each compound’s own page.
