Dsip Purity: 908 Lab Tests Across 423 Identified Manufacturers
18 studies on Dsip curated from PubMed, ClinicalTrials.gov, and EuropePMC. Updated daily.
Bottom line: TitrateLab currently tracks 908 published third-party lab tests of Dsip across 423 identified manufacturers. Among reports with a positive numeric purity result, the average is 99.24%. Within this published corpus, 2 positive purity results were below 90%, and 67 reports showed measured quantity more than 10% below the label claim. These are batch-level observations, not guarantees of product identity, safety, or vendor quality.
Dsip average prices
As of 2026-09-03, vendor-blind retail asking-price averages for the US delivery market, calculated from the same in-stock exact-strength cells as the Peptide Price Index. Shipping is excluded.
| Strength | Average / vial | Observed range / vial | Average / mg | Coverage |
|---|---|---|---|---|
| 2 mg | $5.50 | $5.50–$5.50 | $2.75 | 1 source · 1 offer |
| 5 mg | $7.50 | $6.50–$8.00 | $1.50 | 4 sources · 4 offers |
| 10 mg | $9.50 | $5.50–$11.50 | $0.95 | 6 sources · 6 offers |
Asking prices are not manufacturing cost and do not establish product equivalence, quality, safety, or legality. The refresh date is the catalog build date; individual source observation dates are not available in this snapshot. View full price methodology →
We tested 908 Dsip batches across 423 identified manufacturers
Independent certificate-of-analysis evidence from third-party labs — the data behind the studies. Updated as new COAs are verified. Read the full grey-market analysis →
Within that total, 173 batches have unresolved manufacturer identity. They remain in corpus-level lab evidence and are excluded from named-manufacturer rankings.
Top 3 vendor evidence profiles for Dsip
Eligible vendors have at least 2 deduplicated tests and 2 classifiable identity observations. Rank uses the 95% lower confidence bound on clean identity results; mean positive purity and test count break ties. Missing measurements are not passes. Exact-zero/not-detected and explicit wrong-compound markers count once per adverse certificate. This describes tested batches, not every product or shipment, and is not an endorsement.
| Rank | Manufacturer | Tests | Avg positive purity | Identity adverse results | |
|---|---|---|---|---|---|
| #1 | 22 | 99.48% | 0 of 18 (0.0%) 0 0% / not detected · 0 wrong compound · 4 unclassified | Reveal with Pro → | |
| #2 | 16 | 99.63% | 0 of 16 (0.0%) 0 0% / not detected · 0 wrong compound | Reveal with Pro → | |
| #3 | 9 | 98.08% | 0 of 9 (0.0%) 0 0% / not detected · 0 wrong compound | Reveal with Pro → |
Manufacturer identities are included with Pro. Batch counts and lab measurements remain visible.
Recent certificates: #100836 (99.18%) · #100204 (99.77%) · #100081 (99.03%) · #99545 (99.43%) · #100287 (99.49%) · #100348 (99.01%)
