      I have
      reviewed this quarterly report on Form 10-QSB of Lev Pharmaceuticals,
      Inc.





2)
      Based
      on my knowledge, this quarterly report does not contain any untrue statement
      of
      a material fact or omit to state a material fact necessary to make the
      statements made, in light of the circumstances under which such statements
      were
      made, not misleading with respect to the period covered by this quarterly
      report;





3)
      Based
      on my knowledge, the financial statements, and other financial information
      included in this quarterly report, fairly present in all material respects
      the
      financial condition, results of operations and cash flows of the registrant
      as
      of, and for, the periods presented in this quarterly report;





4)
      The
      registrant's other certifying officer and I are responsible for establishing
      and
      maintaining disclosure controls and procedures (as defined in Exchange Act
      Rules
      13a-15(e) and 15d-15(e)) for the registrant and we have:





a)
      Designed such disclosure controls and procedures, or caused such disclosure  controls
      and procedures to be designed under our supervision, to ensure that material
      information relating to the registrant, including its consolidated subsidiary,
      is made known to us by others within those entities, particularly during the
      period in which this quarterly report is being prepared;





*b)* *[Paragraph
      omitted in accordance with SEC transition instructions contained in SEC Release

c)
      Evaluated the effectiveness of the registrant's disclosure controls and
      procedures and presented in this report our conclusions about the effectiveness
      of the disclosure controls and procedures, as of the end of the period covered
      by this report based on such evaluation; and





d)
      Disclosed in this report any change in the registrant's internal control over
      financial reporting that occurred during the registrant's most recent fiscal
      quarter (the registrant's fourth fiscal quarter in the case of an annual report)
      that has materially affected, or is reasonably likely to materially affect,
      the
      registrant's internal control over financial reporting.





5)
      The
      registrant's other certifying officer and I have disclosed, based on our most
      recent evaluation of internal control over financial reporting, to the
      registrant's auditors and the audit committee of the registrant's board of
      directors (or persons performing the equivalent functions);





a)
      All
      significant deficiencies and material weaknesses in the design or operation
      of
      internal control over financial reporting which are reasonably likely to
      adversely affect the registrant's ability to record, process, summarize and
      report financial information; and





b)
      Any
      fraud, whether or not material, that involves management or other employees
      who
      have a significant role in the registrant's internal control over financial
      reporting.
