Alphex: Independent Lab Review (9 COAs Tracked)
Lab-verified evidenceAn independent, evidence-first review of Alphex — wondering if Alphex is legit? Every number below is sourced from 9 third-party lab certificates of analysis, not vendor marketing.

What the evidence says
Evidence window 2025-09-18 to 2026-08-03Evidence through 2026-08-03. The 8 measured purity results averaged 97.7%; 1 was below 90%. In the last 12 months, 1 of 8 dose results were more than 10% under label; 6 were on target and 1 were over.

How these figures were calculated
A dose result is a certificate that reports a measured amount against the amount printed on the label. Under means more than 10% below the label, over means more than 10% above it, and on target is everything in between, inclusive. Positive purity measurements form the purity mean. When the labeled compound was not detected, that result is reported as an identity failure instead of 0% purity. Finnrick results are excluded from dose figures because that lab measures against the vendor's batch claim rather than the label; their purity and identity results still count. Missing values are never counted as passes.
- 1 of 9 counted certificates lack a usable purity result.
- 1 of 9 counted certificates lack a dose result (a measured amount against the printed label).
- 9 of 9 counted certificates lack a usable endotoxin result.
Underfills on record
Dose results more than 10% under the printed label, worst first. Dated historical evidence, not current performance.

Expected compound not detected
The lab did not identify the compound named on the label. This is an identity failure, not a 0% purity measurement.
No identity failure among 8 reported identity/purity results.
Low purity results
Positive purity measurements below 90%, lowest first. Identity failures are reported separately above.
All 1 low-purity result is shown above. 1 of 8 positive purity results fell below 90%.
Dose results by compound
All time. Compounds with at least 5 dose results; the sample size is shown on every row.
| Compound | Results | Under | On target | Over |
|---|---|---|---|---|
| Retatrutide | 6 | 1 (16.7%) | 5 (83.3%) | 0 (0.0%) |
2 more compounds with fewer than 5 dose results (2 results in total) are not ranked: too few results to describe a pattern.
Endotoxin
Reported separately from purity and dose. Only classifiable results count: a result the lab reported as pass, borderline or fail. Silence is not a pass.
No classifiable endotoxin result is on file for any of the 9 counted records.

Frequently asked
purity & lab evidenceIs Alphex legit?
TitrateLab does not rank or recommend vendors; it reports what independent labs measured. Alphex shows mixed measured purity (97.7% mean across 8 positive purity measurements). Dose accuracy is mostly on target: in the last 12 months 6 of 8 dose results were on target, 1 under label and 1 over; all time 6 of 8 on target, 1 under and 1 over. These results describe tested batches, not every product or shipment.
What is Alphex's average purity?
97.7% mean measured purity across 8 positive third-party lab results; 7 were at or above 90% and 1 was below.
How many Alphex lab certificates has TitrateLab tracked?
9 third-party certificates from 2025-09-18 to 2026-08-03, covering 3 compounds.
How accurate are Alphex's doses?
Dose accuracy is mostly on target: in the last 12 months 6 of 8 dose results were on target, 1 under label and 1 over; all time 6 of 8 on target, 1 under and 1 over. A dose result compares the measured amount with the amount printed on the label: under is more than 10% below, over is more than 10% above, on target is everything in between. Finnrick results are excluded because that lab measures against the vendor's batch claim. Missing values are never counted as passes.
Has Alphex failed an endotoxin test?
No classifiable endotoxin result is on file for any of the 9 counted records.
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. Dose results compare the measured amount with the printed label and are reported as under, on target or over; Finnrick results are excluded from dose figures. Results reflect the batches that were tested and are 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.
