 I,  David
          Koos, Chief Executive Officer, certify that:
 
 1. I
          have reviewed this form 10-QSB/A for the quarter ended March 31, 2006 of
          Frezer,
          Inc.;
 
 2. Based
          on my knowledge, this 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 report, fairly present in all material respects the financial
          condition, results of operations and cash flows of the small business issuer
          as
          of, and for, the periods presented in this report;
 
 4.
          I am
          responsible for establishing and maintaining disclosure controls and procedures
          (as defined in Exchange Act Rules 13a-15(e) and 15d-15(c)) for the small
          business issuer and  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 small business issuer, including its
          consolidated subsidiaries, is made known to us by others within this entity,
          particularly during the period in which this report is being
          prepared;
 
 (b) Omitted;
 
 (c)
           Evaluated the effectiveness of the small business issuer’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 quarterly report any change in the small business issuer’s
          internal control over financial reporting that occurred during the small
          business issuer’s most recent fiscal quarter (the small business issuer’s fourth
          fiscal quarter in the case of an annual report) that has materially affected,
          or
          is reasonably likely to materially affect, the small business issuer’s internal
          control over financial reporting; and
 
 5. 
I
          have disclosed, based on my most recent evaluation of internal control
          over
          financial reporting, to the small business issuer’s auditors and the audit
          committee of small business issuer’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 small business issuer’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 small business issuer’s internal
          control over financial reporting.

 *The
          introductory portion of paragraph 4 of the Section 302 certification that
          refers
          to the certifying offices’ responsibility for establishing and maintaining
          internal control over financial reporting for the company, as well as paragraph
          4(b), have been omitted in accordance with Release No. 33-8545 (March 2,
          2005)
          because the compliance period has been extended for small business issuers
          until
          the first fiscal year ending on or after July 15,
          2006.
