A brief comment on Who is Who in Insulin Potentiation Therapy (IPT or IPTLD)

The Discoverer of Insulin Potentiation Therapy was the late Donato Perez Garcia, MD (1896-1971).
Forty-eight years after his death, I am proud to represent the legacy of my grandfather and my father after him, since becoming licensed as a physician in 1983. This legacy is a unique one, with father passing along to son the gifts, wisdom, and knowledge gained only through many years of invention, triumphs, and struggle in the practice of medicine.
I seek to pass along the same hard fought wisdom, knowledge, and gifts through our Insulin Potentiation Therapy training and certification program, offered in concert with the European Academy for IPT (EAIPT). Certified IPT Practitioners who have successfully completed and maintained their education in the practice of the therapy are listed on the Academy for IPT Directory website, at: 

A Statement on Competing Organizations

Dr. Donato Perez Garcia was a founding member of an organization, which has subsequently positioned itself as a competing organization in respect to the offering of education and training in the technique known as Insulin Potentiation Therapy or IPT for profit. Dr. Donato resigned from this organization, and requested that all materials and references to insulin potentiation therapy, IPT or IPTLD not to be used in the promotion of this organization’s operations. As of 2019, this organization, which has positioned itself as a competing organization does not have an agreement or mutually agreed upon contract which legally and ethically grants training in Insulin Potentiation Therapy (IPT), as discovered by the late Donato Perez Garcia, MD., and developed through my work, and that of my colleague Steven G. Ayre MD. The educational endorsement of training in IPT by this competing organization has been misappropriated without written permission, and without legal or ethical right.
Dr. Donato Perez Garcia (3rd generation of MD’s) recognizes that there are some fine doctors who publicly identify as members of the competing group, however several have not been properly trained or renewed their IPT Certificate. Dr. Donato has vigorously invited these doctors to renew or take the IPT training workshop.
Dr. Donato does not wish to censure any individual physician colleague or disseminate defamatory material on the competing organization. His motives – aligned with those of the European Academy for IPT (EAIPT) - are to promote an effective and standardized method of education and training on the techniques, and to ensure the best possible outcome for patients seeking this treatment alternative.
The organization which has positioned itself to compete with Donato Perez Garcia MD on the education of Insulin Potentiation Therapy does not have the authority to issue IPT Certificates or list trained doctors on IPT the medical treatment, as discovered by the late Donato Perez Garcia, MD and contemporarily promoted by his grandson of the same name. The organized efforts of any competing organization in seeking profit from the dissemination and education of the technique known as Insulin Potentiation Therapy (IPT) are in violation of the respectful acknowledgement of copyright law and medical ethics.

Who is Who in Insulin Potentiation Therapy IPT or IPTLD

What are the requirments to be a Certified IPT / IPTLD Doctor.

Safety is the highest priority when performing any procedure on a patient. Donato Perez Garcia, MD., recognizes that there is variability in the types and numbers of procedures performed by IPT trained medical doctors in practice. Medical Doctors who perform any procedure including IPT, must obtain the appropriate training to safely and competently perform that procedure. It is also expected that the medical doctor be thoroughly evaluated and credentialed as competent in performing a procedure before he or she can perform a procedure unsupervised.

Certification of competence of a medical doctor in Insulin Potentiation Therapy (IPT or IPTLD®). So Who Can “Certify” on Insulin Potentiation Therapy or IPT / IPTLD®?
As of this date the only person who can give someone these credentials is the person who has the most experience on the IPT technique, owns the copyrights of the procedure and this is Donato Perez Garcia,MD. This process needs to be re-examined and re-certified annually to insure that your IPT/IPTLD® skills are current.

"Certificating" is a term used to denote the issuance of a document attesting that the holder has met requirements of codes, standards or specifications. Certificating may be accepted as proof that the holder has met the published requirements. Certification is the written testimony of qualification or the procedures leading to that written testimony. This also means that if you move you may have to recertify all over again.

All professional groups are very clear that your instructor cannot certify you.

Donato Perez Garcia,MD and the Scientific Board of The European Academy for IPT requires documentation that candidates for certification of medical competence in insulin potentiation therapy or IPT, are competent in: (1) patient care and procedural skills, (2) medical knowledge, (3) practice-based learning and improvement, (4) interpersonal and communication skills, (5) professionalism and (6) systems-based practice.

For Certification in insulin potentiation therapy or IPT, Donato Perez Garcia,MD and the Scientific Board of The European Academy for IPT has identified a limited set of procedures for which it expects all candidates to be competent with regard to their knowledge and understanding. This includes (1) demonstration of competence in medical knowledge relevant to insulin potentiation therapy or IPT/IPTLD® through the candidate's ability to explain indications, contraindications, patient preparation methods, chemotherapy and non chemotherapy drug indications and side effects, pain management, proper techniques for handling specimens and fluids obtained, and test results (2) ability to recognize and manage complications and (3) ability to clearly explain to a patient all facets of the procedure necessary to obtain informed consent.  
When it comes to Insulin Potentiation Therapy or IPT or IPTLD® the medical technique was invented by my grandfather, continued and improved by my father and myself. When it comes to the teaching of the technique, the materials, the copyright and intellectual property, those are held by myself / the legacy of the family.

When you were trained in the IPT technique, you were required to follow guidelines. No one should take off with information and then use it the way they see best, disregarding the recommendations which were taught.

I welcome your comments, ideas, and thoughts. I ask this from every physician. However I do not ask that everyone claims IPT to be their own. That was never the intention of any member of the Donato legacy. Our intention is to move forward with the betterment as a whole and I only ask a listening ear and respect during the process.

Of course a doctor can continue to use the letters IPT. However, if they claim to use the trademarked protocol, use the papers and the information available in magazines and books, it must be understand that there are administration rules to follow as Dr Donato Perez teaches and practices. If guidelines are not followed, where is the support for the technique being used? Yes, I hold the legal rights, copyright and manual to IPT / IPTLD®. This is not to say I hold nor want to claim the right to all future advancements.

The IPT technique has been in use since 1930.  Many substances and delivery methods have been tested since that date, some did not produce the expected, or better, results and today what we must do is adhere to a standard protocol. Then we can give information about what substances are best combined, in what time frame; what is best to use and best not to use.

If someone chooses to open their own school about IPT, I ask that they do not use my name, my family name and/or references to the name.  Many long hours and hard work is behind this work; this requires respect and honor.

I thank and support those physicians who choose excellence in the care of protocols and standards.
