The batch-by-batch distribution is a Pro feature
See every one of Felix Chemical Supply's 172 assayed batches plotted by purity around the 99.5% average — the real per-batch readings behind the headline stats.
Go Pro — $9/mo or $33 lifetimeDose distribution
154 batches dose-testedPurity 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 evidenceIs Felix Chemical Supply legit?
TitrateLab tracks 375 third-party lab certificates of analysis for Felix Chemical Supply, averaging 99.5% tested purity across 172 assayed batches, with 95% of those batches in spec on both purity (≥90%) and labeled dose (filled to within 10% of the labeled amount); 8 assayed batches were significantly underdosed (worst -60% vs the labeled amount) (tests dated 2025-10-01 to 2026-06-30). 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 Felix Chemical Supply's average tested purity?
Across the 172 assayed batches TitrateLab tracks for Felix Chemical Supply, the mean third-party-tested purity is 99.5%. 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 Felix Chemical Supply?
TitrateLab tracks 375 published third-party certificates of analysis for Felix Chemical Supply spanning 62 distinct compounds. Each certificate links to its own public page with the purity, test method, issuing lab, and test date.
What share of Felix Chemical Supply's tested batches are in spec on purity and dose?
95% of the 172 assayed batches TitrateLab tracks for Felix Chemical Supply (164 of 172) were in spec on BOTH tested purity (at or above 90%) and labeled dose (filled to within 10% of the labeled amount). 8 assayed batches were significantly underdosed against the label (worst -60%), 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 →
