Frequently asked
Common questions
How many vendors sell Thymalin?
14 vendors currently list Thymalin on Peptide Vendor Reviews. None of them have published independent lab results yet.
What is the cheapest Thymalin per mg?
The lowest tracked price is $1.29 / mg per milligram. That figure comes from live vendor catalogs and is re-checked every 24 hours, so the cheapest vendor changes.
Has Thymalin been independently tested?
Not yet. Thymalin is tracked for pricing, but no third-party results are on file. Read our sample-testing information or contact the review desk with a source certificate.
How are vendors ranked?
Vendors are ranked by independent third-party HPLC and Mass Spec testing. The default sort surfaces the lowest price per milligram first; you can toggle to sort by purity score or test volume. Peptide Vendor Reviews does not accept payment to influence rankings.
What does $/mg mean?
$/mg is the price per milligram of peptide, calculated from the listed product price and the vial size. It's the most accurate way to compare costs across vendors that sell different vial sizes.
How often are prices updated?
Prices are scraped from vendor websites continuously and refreshed every 24 hours. Each row shows when its price was last verified.
What's a purity score?
A purity score is the average HPLC purity percentage from all independent lab tests we've run on samples from a given vendor's Thymalin. A score of 10/10 means 100% purity. Most reputable research peptides score 8.5–9.5.
Are these peptides for human use?
No. All peptides listed are sold for laboratory research purposes only and are not intended for human consumption or clinical use. Always consult your jurisdiction's regulations before purchasing.
Why do some vendors have no test data?
When a vendor has scraped pricing but no lab tests on file yet, they're flagged as 'Not yet tested.' We're constantly expanding test coverage; vendors can submit samples or wait for our next sweep.
