What if a therapy could be designed specifically for your body — targeting the exact genetic sequences driving your illness?
That's the premise behind Supportive Oligonucleotide Therapy, or SOT. Now known as Q-REstrain, it represents one of the most individualized approaches available in integrative medicine today.
Key Takeaways
Supportive Oligonucleotide Therapy — now rebranded as Q-REstrain by its developer, RGCC International — is a precision-based IV therapy that target sillness at the genetic level.
Unlike generalized treatments, SOT is built from scratch for each patient. A blood sample is analyzed to identify the specific gene sequences driving your condition. A custom therapeutic molecule is then created to silence those genes — disrupting the disease's ability to survive and progress.
In short: it's a highly targeted tool designed to work with your body' sown biology.
The process follows three core steps:
1. Gene Identification A small blood sample is sent to the RGCC laboratory, where scientists identify and validate the genetic sequences specific to your condition — whether cancer cells, Lyme bacteria, or a virus.
2. Custom Molecule Creation The lab produces a tailored oligonucleotide — a short segment of DNA or RNA — designed to bind to and block those specific genetic sequences. This is called antisense therapy: the molecule acts as a "key" that fits a precise "lock" within the harmful cell orpathogen, shutting down its critical functions.
3. IV Infusion and Ongoing Action The therapy is delivered via a single IV infusion. Once in the bloodstream, the molecule works continuously — targeting and neutralizing harmful cells or pathogens 24 hours a day for up to six months.
SOT is used as a complementary therapy for:
SOT is offered as a supportive, integrative option — not a replacement for conventional care. Your Indigo provider will determine whether it's appropriate for your situation and health history.
Before treatment: A blood draw is taken and sent to RGCC's laboratory. It typically takes approximately four weeks to prepare your custom therapy.
During the infusion: SOT is administered in a comfortable clinical setting. The infusion generally takes one to a few hours. Pre-medications are given to support tolerance.
After treatment: Some patients experience mild, short-lived fatigue or flu-like symptoms as the therapy begins working. Many of our patients at Indigo have responded well, reporting gradual and meaningful improvement over the following weeks — and we continue to monitor outcomes closely.
Follow-up: Periodic lab testing is scheduled to monitor progress and assess effectiveness.
Most treatments work broadly — affecting healthy cells alongside harmful ones.
SOT is designed to do the opposite: target only the specific genetic material linked to your condition, leaving healthy cells unaffected. Because the therapy is built from your own blood and customized to your unique biology, it cannot be used for anyone else.
That level of personalization is rare in medicine.
SOT has been used in thousands of patients worldwide through RGCC-certified clinics, and RGCC has tracked outcomes across a large international patient database, with positive trends in both tolerability and response. Our own clinical experience at Indigo has been encouraging — manypatients report meaningful improvement in the weeks following treatment.
That said, SOT is an emerging therapy offered as part of a thoughtful, individualized treatment plan.
It is not a standalone cure, and it is not appropriate for every patient or every condition. Our team will conduct a thorough evaluation — including relevant lab work — to determine whether SOT is a suitable and beneficial option for you.
The goal, as always, is precision: the right tool, for the right patient, at the right time.
