    Know all by these presents, that the undersigned hereby constitutes and
appoints each of Joshua Cohen, Justin Klee and James Frates, signing
singly, the undersigned's true and lawful attorney-in-fact to:

(1)   execute for and on behalf of the undersigned, in the undersigned's
capacity as an officer and/or director of Amylyx Pharmaceuticals, Inc. (the

assignment of codes to the undersigned to be used in the transmission of
information to the United States Securities and Exchange Commission using the
EDGAR System, and (ii) Forms 3, 4 and 5 and amendments thereto in accordance
with Section 16(a) of the Securities Exchange Act of 1934, as amended, and
the rules thereunder;

(2)   do and perform any and all acts for and on behalf of the undersigned
which may be necessary or desirable to complete and execute any such Form 3,
4 or 5 and amendments thereto and timely file such form with the United

authority; and

(3)   take any other action of any type whatsoever in connection with the
foregoing which, in the opinion of such attorney-in-fact, may be of benefit
to, in the best interest of, or legally required by, the undersigned, it
being understood that the documents executed by such attorney-in-fact on
behalf of the undersigned pursuant to this Power of Attorney shall be in such
form and shall contain such terms and conditions as such attorney-in-fact may
approve in such attorney-in-fact's discretion.

    The undersigned hereby grants to each such attorney-in-fact full power
and authority to do and perform any and every act and thing whatsoever
requisite, necessary, or proper to be done in the exercise of any of the
rights and powers herein granted, as fully to all intents and purposes as the
undersigned might or could do if personally present, with full power of
