Frequently asked
purity & lab evidenceIs Optitropin EU legit?
TitrateLab tracks 60 third-party lab certificates of analysis for Optitropin EU, averaging 99.6% tested purity across 11 assayed batches, with 91% of those batches in spec on both purity (≥90%) and labeled dose (filled to within 10% of the labeled amount); 1 assayed batch was significantly underdosed (worst -11% vs the labeled amount) (tests dated 2022-08-12 to 2025-12-31). 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 is Optitropin EU's average tested purity?
Across the 11 assayed batches TitrateLab tracks for Optitropin EU, the mean third-party-tested purity is 99.6%. Purity is measured on the specific batches that were submitted for analysis and is not a guarantee for any other lot.
How many lab certificates does TitrateLab track for Optitropin EU?
TitrateLab tracks 60 published third-party certificates of analysis for Optitropin EU spanning 31 distinct compounds. Each certificate links to its own public page with the purity, test method, issuing lab, and test date.
What share of Optitropin EU's tested batches are in spec on purity and dose?
91% of the 11 assayed batches TitrateLab tracks for Optitropin EU (10 of 11) were in spec on BOTH tested purity (at or above 90%) and labeled dose (filled to within 10% of the labeled amount). 1 assayed batch was significantly underdosed against the label (worst -11%), 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.
Answers are derived from the third-party lab certificates TitrateLab tracks for this vendor and describe tested purity only. This is research-use-only information, not medical advice and not a recommendation to purchase or use any product.
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 →
