Thymalin
thymus polypeptide extract · Thymalinum · polypeptide mixture. The index holds 14 assay reports on this compound across 1 batches from 1 suppliers.
Analytical fingerprint
Hand-authored chemistry. These properties describe the substance and do not change when a record is added.
Thymalin is a thymic peptide extract, not a defined chemical entity, and it has no monoisotopic mass, no retention time and no meaningful purity figure. The index catalogues it so that submissions can be recorded honestly rather than silently discarded, and every thymalin record reports the compositional profile (peptide mass distribution by SEC, total peptide by Lowry or BCA, water, ash) with purity marked NOT APPLICABLE. Suppliers that print a "99 % purity" COA for thymalin are listed on /anomalies/ax-r04/, because a purity claim on an extract is not a measurement.

What the index has observed
Arithmetic over the 14 records the index holds. Aggregates on this page are computed over the records the index holds, which are not a random sample of the material on the market. Lots that get tested are lots someone chose to test. Read every figure here as a description of this dataset rather than as an estimate of a population.
The index holds 14 records for Thymalin, and purity is not a defined quantity for it. That is a gap in the index, not a finding about the compound.
