Item 8.01 Other Events – Letter to Shareholders and Interested Parties.

To All Shareholders and Interested Parties:

Primarily due to staleness, on or about March 12, 2024 Therapeutic Solutions International, Inc. (“TSOI” and/or the “Company”) withdrew its corporate action, the dividend distribution of certain shares of its partially owned subsidiary (44.56%), Campbell Neurosciences, Inc. (“CNSI”), that had been originally filed on or about March 27, 2023, and, deeming it in the best interest of the Company and TSOI Shareholders, and with the consent of a majority of the eligible voting shares (55.5%), caused to be filed a new corporate action with FINRA on or about May 3, 2024 to accomplish the desire to provide a loyalty award to TSOI shareholders that elect to accept, in the form of a dividend distribution of CNSI shares the Company beneficially owns. The following resolutions based on shareholder consents and approvals of the boards of both TSOI and CSNI were adopted:

IT IS RESOLVED, that it is in the best interest of the Company and its shareholders to refile the corporate action as soon as practicable to offer a loyalty dividend to TSOI shareholders in the form of up to Ten Million (10,000,000) shares of Campbell Neurosciences, Inc. (“CNSI”) beneficially owned by TSOI by issuing a prorated loyalty dividend to TSOI shareholders in CNSI at a ratio of 0.0022 shares of CNSI stock for each one (1) share owned in TSOI stock (10,000,000/4,458,184,291 = 0.002243065640016) as of April 30, 2024 (the “Dividend Offer”) on the record date of the action of May 15, 2024 (“Dividend Offer Date”), the Dividend Offer to remain open for Ninety (90) days from the Dividend Offer Date (on or about August 14, 2024), the initial corporate action filed on or about 3/27/2023 being withdrawn on or about 3/12/2024 principally due to staleness.

RESOLVED FURTHER, that the officers of the Company are hereby authorized to do and perform any and all such acts, including the filing of a Form 8-K regarding this corporate action, and execution and issuance of any and all documents, as said officers shall deem necessary or advisable, to carry out the purposes of the Company and its corporate action.

A Shareholder’s Rights Agreement may be enclosed or will be provided at the time of issuance of the loyalty dividend in CNSI common stock and any associated transactional documents.

Please do not respond to the information in this Form 8-K until you have heard from either your broker/dealer, the Distribution Agent or the Issuer regarding the dividend.
