BioLab does not publish batch COAs

On your own website, an analysis certificate is not available for any batch. Whoever orders here gets no proof of what is in the vial he holds in his hand: no purity, no endotoxin load, no heavy metal values.

If measured values are further down on this page, they come from an external blank test and refer to a single sample. They say nothing about the batch that is in the next package. This is exactly what batch COAs would be for.

What BioLab Strong power

    Where BioLab Weakness

    • Severe single finding in the entire test field: 619,114 EU/Vary endotoxins in BPC-157. For comparison, the best value in the same test is below 1. Test report 195790
    • For retatrutide, 150.5% of the label, i.e. half more than declared, plus 75.743 EU/Vary endotoxins. Overcrowding is not an advantage, it makes the dosage incalculable
    • No certificates of analysis, no laboratory named, no batch transparency on the page (verified 31.07.2026)
    • No imprint, no legal entity, no address found
    • Payment types are not shown on the page
    • No Trustpilot profile, so no independent evaluation source can be verified

    Score breakdown

    How the overall score of 32/100 composed. Below each bar is where the value is based.

    Laboratory testing (25%)18 / 100

    The own laboratory site describes a test system for dietary supplements containing heavy metals, pesticides and microbiology, does not mention a laboratory and does not mention endotoxin. A customer reports on gutefrage.net, some not found laboratory reports and some not scanned. The external measurement matches: 619,114 EU/Vary Endotoxin for BPC-157, by far the highest value in the field, and 150.5 percent label fidelity for retatrutide.

    Legal Entity & Traceability (25%)30 / 100

    As a contact, only a British mobile number is visible, an imprint was not found. The search under different addresses is still pending.

    Delivery & Purchase Processing (20%)60 / 100

    German-language shop with delivery page, shipping conditions in detail not yet collected.

    Product Framework (30%)25 / 100

    BPC-157 is sold as a 60-piece capsule and as a nasal spray. Both are formats for intake by people, in addition, the shop leads vitamins and nutritional supplements according to health goals.

    Externally audited

    These values do not BioLab commissioned. The samples were collected from third parties in Yesnoshik Analytical Submitted and measured in the blind test, the manufacturer knew nothing about it. We have neither given nor paid for the order. Each value bears its test number, and where there is a key, the link to the original leads to the laboratory.

    In the same order, further samples were measured, which do not appear here because the manufacturer is not named on the test sheet or cannot be clearly assigned to a shop. A test report evaluates a batch, not a company. A good value does not mean that every delivery looks like this, a bad one does not mean that it is worked poorly throughout.

    Check your own batch — what such an analysis costs, how it works and what two ways there are.

    Lab Test Status: No Public COAs

    BioLab does not publish batch-related analysis certificates on its own website. Thus, there is no independent evidence of purity, endotoxin load or heavy metal levels before purchase.

    Without a publicly available batch COA, there is no basis for a reliable quality assessment. Until that changes: Recommendation against buying from this vendor.

    vendors with published COAs can be seen at the Supplier overview — sorted by score.
