Find a batch from Lobster▸ Vendor trust profile
An independent, evidence-first review of Lobster — wondering if Lobster is legit? Every number below is sourced from 12 third-party lab certificates of analysis, not vendor marketing. The aggregate lab metrics and purity distribution are free; certificate-level records, pricing & stock are TitrateLab Pro.
Evidence through 2026-07-02. The 10 measured purity results averaged 98.1%; 0 were below 90%. In the last 12 months, 0 of 2 dose results were more than 10% under label; 1 were on target and 1 were over.

98.1%mean across 10 measured results
10 of 10 at or above 90% purity
Dose results: measured amount against the printed label
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.
Across 2 dose results and 10 reported identity/purity results, no result was more than 10% under label, no labeled compound went undetected, and no positive purity measurement fell below 90%.
This does not mean every product was tested. Overfills, endotoxin coverage, and missing evidence are reported separately on this page.All time. Compounds with at least 5 dose results; the sample size is shown on every row.
2 more compounds with fewer than 5 dose results (2 results in total) are not ranked: too few results to describe a pattern.
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.
Endotoxin was reported on 2 of 12 counted records (16.7%). No failures were recorded in those 2. Coverage is too limited for a vendor-wide conclusion.

I have now placed two orders with Lobster. He has no presence on this forum but a lot of people are talking about him here, so I figured I would write a short…

TitrateLab does not rank or recommend vendors; it reports what independent labs measured. Lobster shows high measured purity (98.1% mean across 10 positive purity measurements). Dose accuracy is mixed and no recent result was under label: in the last 12 months 1 of 2 dose results were on target, 0 under label and 1 over; all time 1 of 2 on target, 0 under and 1 over. These results describe tested batches, not every product or shipment.
98.1% mean measured purity across 10 positive third-party lab results; 10 were at or above 90% and 0 were below.
12 third-party certificates from 2025-06-17 to 2026-07-02, covering 5 compounds.
Dose accuracy is mixed and no recent result was under label: in the last 12 months 1 of 2 dose results were on target, 0 under label and 1 over; all time 1 of 2 on target, 0 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.
Endotoxin was reported on 2 of 12 counted records (16.7%). No failures were recorded in those 2. Coverage is too limited for a vendor-wide conclusion.
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.
