IPT Insulin Potentiation Therapy
Cancer Treatment

Also known as IPTLD or Insulin Potentiation Low Dose Therapy is a metabolic supported chemotherapy that includes: fasting, IPT and traditional chemotherapy.

IPT is one of our key therapies in the Functional Oncology Clinic and we are proud to say that Dr. Donato Perez, one of our specialists is the grandson of the IPT creator and the rightful owner of IPTLD therapy.

What is Insulin Potentiation Therapy?

IPT or IPTLD is a treatment that targets a cell by changing the bio-physio-chemical constants and parameters of the blood. This pathway initially attacks the cancerous cell itself through its intra-cellular environment and then by the extra-cellular environment by permeabilizing the cell membrane.

In more simple words, IPT is a chemotherapy delivered at a fraction of the normal dose and it is only directed to the cancerous cells and not the patients entire body, which significantly reduces or eliminates the dangerous side-effects of conventional chemotherapy.


IPT History

Insulin Potentiation Therapy (IPT) was created and developed in 1930 by Donato Perez Garcia, Sr. (1896 – 1971). It has been used with success in cancer patients since 1946. Eighty years and three generations of medical doctors have worked to bring an exceptional treatment for cancer and other degenerative diseases.

Our IPT specialist, Dr. Donato Pérez García has been a practice physician since 1982 and is the recipient of their collective eighty-five years of experience in IPT treatment and is the most experienced IPT medical doctor in the world, he heralds over 46,000 treatments and has been in practice as an IPTLD medical doctor for more than 30 years.

His scientific presentations on the treatment at major national and international scientific conferences have earned him recognition from the National Institutes of Health, National Cancer Institute and the Office of Cancer Complementary and Alternative Medicine (OCCAM).

His treatment programs are based on years of substantiated medical and scientific research conducted by leading cancer treatment pioneers. In addition, he trains physicians from around the world; more than 870 doctors from 32 countries.


The demand for IPT has increased and with that, the certification of M.D.’s. Unfortunately, there are doctors and organizations who have stolen the knowledge on IPT and trained other doctors to make profit.

Not every doctor can be a IPT specialist, it takes time, effort, preparation and a thorough evaluation to certify a doctor as an official I.P.T. Physician, capable and competent to perform this protocol, always keeping the security of the patient at high priority.

Every year Dr. Donato and his team organize IPT conferences and workshops given by our own Dr. Donato, to be officially certified. Patients and people from all over the world have free access to “The List” of Certified I.P.T. Practitioners, trained and endorsed by Donato Perez Garcia, M.D., which is updated on a quarterly basis.


Doctors and/or organizations that are not on this list are not authorized to practice/train in I.P.T. Any disregard to do so, in due time, will have to reported to proper authorities, both in Mexico and the United States of America.
