  • BioPrecise LLCAug 3, 2026 · Krause Analytical
    purity under 99.5%; amount in the vial more than 35% off the label · purity 98.30% · fill +41.0% · Certificate

    purity under 99.5% · purity 98.50% · fill -0.6% · Certificate

Before you buy DSIP: check the certificate

  • Look at the shop's grade for DSIP, not its average. HkRoids has the most DSIP tests (3); a shop with one or two tests has not shown it is consistent.
  • 75% of these vials were sent in anonymously by members of the public; the rest were bought by the independent tester or sent by the shop itself. Results from vials a shop chose to send are the weakest evidence.
  • 2 labs tested them, mostly Krause Analytical and BTLabs. Ask for the certificate for your batch and check it on the lab's own site.
  • Run the vendor checklist before paying, and read how the grades work.

Full grading methodology

Quality is multi-dimensional

Each peptide assessment combines its lab results, evidence confidence and the vendor's reviewed business signals. Lab scoring considers identity, purity, quantity and contamination findings. Unreviewed business signals do not earn a passing grade.

Value has a quality threshold

Best value is the lowest recorded $/mg among the top 25% of active, graded vendors for this peptide, rounded up. Membership is set before checking prices; a missing listing never widens the pool.

Compare like with like

Quality leader is the first vendor in the shared ranking that has a website we can send you to, even without a price. Lowest price is the lowest recorded listing $/mg, independent of grade. Confirm the current price, shipping and tax on the vendor's site. Estimates never qualify as offer picks; grades are not safety, sterility or approval.

Frequently asked

Common questions

Where can I buy DSIP?
172 shops list DSIP here, 2 of them with independent lab tests on record. Compare each shop's grade for DSIP and its current price per mg in the table above, then check the certificate for your batch.
How many vendors sell DSIP?
172 vendors currently list DSIP on Peptide Vendor Reviews. 2 of them have published independent lab results.
What is the cheapest DSIP per mg?
The lowest tracked price is $0.75 / mg per milligram. That figure comes from live vendor catalogs and is re-checked every 24 hours, so the cheapest vendor changes.
Has DSIP been independently tested?
Yes — 4 independent lab tests across 2 vendors. Each result is published in full, including the ones that fail.
How are vendors ranked?
By the shared quality assessment: independent lab results for this peptide, how strong that evidence is, and reviewed business signals. The table opens with the highest-rated vendors first; you can re-sort it by price. 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 recorded from vendor websites. Each row shows its recorded timestamp where available. Prices, stock and discounts may have changed; no refresh schedule is guaranteed.
What's a purity score?
Measured purity is the chromatographic purity reported for tested DSIP samples in the source certificates. A composite grade is not a purity percentage. Neither establishes sterility, safety, efficacy or the contents of an untested vial. We publish records; we do not claim to have commissioned every test.
Are these peptides for human use?
This site does not provide human-use guidance or assess suitability for human consumption or clinical use. Listings and analytical results are not evidence of regulatory approval or lawful sale in any jurisdiction.
Why do some vendors have no test data?
A price listing does not imply laboratory testing. 'Not yet tested' means no independent sample records are on file here; it does not establish that no testing exists elsewhere.
