Dose distribution

247 batches dose-tested

Purity tells you how clean the peptide is. Dose tells you how much you actually got — tested milligrams vs the labeled amount. A vial can be 99% pure and still badly underfilled, which never shows on the purity chart. On-target means within ±10% of label; anything outside (under or over) is off-target.

Frequently asked

purity & lab evidence

Is Wuhan Wansheng Biotechnology legit?

TitrateLab tracks 247 third-party lab certificates of analysis for Wuhan Wansheng Biotechnology, averaging 97.4% tested purity across 247 assayed batches, with 80% of those batches in spec on both purity (≥90%) and labeled dose (filled to within 10% of the labeled amount); 44 assayed batches were significantly underdosed (worst -100% vs the labeled amount) (tests dated 2025-08-04 to 2026-07-17). These are purity analytics from independent certificates, not vendor marketing — TitrateLab does not rank or endorse vendors, and this is research-use-only information, not a recommendation to purchase or use any product.

What share of Wuhan Wansheng Biotechnology's tested batches are in spec on purity and dose?

80% of the 247 assayed batches TitrateLab tracks for Wuhan Wansheng Biotechnology (197 of 247) were in spec on BOTH tested purity (at or above 90%) and labeled dose (filled to within 10% of the labeled amount). 44 assayed batches were significantly underdosed against the label (worst -100%), so they are counted as out of spec even where tested purity was high. This reflects only the batches that were tested and is analytic information for research use, not a quality guarantee for any order.

How this is sourced. TitrateLab tracks certificates of analysis posted by the community and verified against the issuing lab. Purity, test dates, and compound names shown here are the same facts published on each public certificate page — aggregated, never edited. The in-spec rate counts a batch only when it clears both purity (≥90%) and labeled dose (filled to within 10% of label, where dose data exists); it reflects the batches that were tested and is not a guarantee of every order. Scores come only from lab data — no vendor pays for placement, and customer orders or Pro never move a grade. Browse the COA corpus →
