    Clear strengths

    Every material states its strength on the page, so options compare directly.

    Matched certificate

    The certificate issued with your order belongs to the lot in the vial, not to a representative batch.

    No guidance supplied

    We publish the analytical record and the storage condition, and nothing beyond that.
