Insulin Potentiation Therapy
( IPT )

Cancer chemotherapy
-- without major side effects.

Gentle cancer treatment
-- without trauma.

Infectious disease treatment:  faster and more effective.  
Could fight drug resistance.

Available to patients today, with no need to wait years for government (FDA) approval.

More than 70 years of  successful use.   

With IPT, regular drugs act like "super" drugs, for treatment of many different diseases.

These are observations that some IPT doctors have reported for many years.

Supported by scientific papers, and reports from many doctors.  However, despite more than 140 years of cumulative reported IPT success, and billions of dollars spent on other medical research, no clinical or laboratory research on IPT has been done or funded... yet.

IPT deserves laboratory studies and clinical trials.

"The second discovery of insulin."

IPT is insulin potentiation therapy, a non-diabetic use of the hormone insulin to dramatically improve effectiveness and delivery of standard medications.  
IPT has an outstanding 135 doctor-year track record (115 years for cancer) over 72 years, and is ready for clinical trials and widespread use.

Donato Perez Garcia MD and IPT patientCancer treatment with IPT is reported to be gentler, safer, more effective, and less expensive, with no surgery, no radiation, and usually no side effects. 

Breakthrough results have also been reported for arthritis, as well as for infectious, respiratory, cardiovascular, neurological, and other diseases.

This slight modification of standard medicine could help many medications act like super drugs, with better results for many millions of patients.  The US National Institutes of Health has expressed interest in clinical trials of IPT for cancer, but has so far provided no funding. 

Donato Perez Garcia MD (1896-1971), discoverer of IPTIPT is 21st century medicine. Donato Perez Garcia y Bellon MD (1930-2000) Discovered in 1926 by Donato Perez Garcia MD, fostered by his son and grandson, with 140+ doctor-years of experience over 72 years, yet still unknown by the world, IPT is just starting a scientific and clinical rebirth.
