    High-Test FECO – Ultra-Potent Full Extract Cannabis Oil

    High-Test FECO is King Harvest’s most concentrated THC oil, delivering uncompromising potency with minimal plant material. Designed for late-stage cancer, tumor application, severe pain, or budget-conscious long-term use, this is THC in its purest, most medicinal form.

    Potency: Ultra-High THC (90%+) Type: Solvent-Free Full Extract Cannabis Oil (Flower-Only, Lab-Tested) Best For: RSO-style cancer therapy, severe pain, suppository use, budget-conscious care

    Originally developed for severe pain and inflammation, High-Test FECO was created for patients seeking the absolute strongest THC content available—without the chlorophyll, waxes, or chemical residues common in traditional RSO. This flower-only extract is ideal for advanced-stage illness and large-dose protocols, delivering a clean, lab-tested experience trusted by patients and caregivers alike.

    Why Patients Choose High-Test FECO

    • Maximum THC: 90%+ THC concentration for uncompromising potency
    • Cleaner Than RSO: Solvent-free extraction with reduced plant matter and zero additives
    • Flexible Use: Suitable for ingestion, suppositories, topicals, or capsules
    • Most Economical: High strength allows patients to stretch their medicine further

    Best For These Applications

    • Direct tumor application (e.g., skin cancer)
    • Suppository use (high-dose without psychoactivity)
    • Late-stage cancer protocols for RSO-style patients
    • Chronic pain and PTSD relief (especially for veterans)

    How It Works

    High-Test FECO is focused on ultra-potent THC delivery, removing excess chlorophyll and plant compounds to leave behind a purified full extract. By isolating the therapeutic compounds from cannabis flower, it offers consistent dosing and maximum absorption for patients who require aggressive cannabinoid intervention—often at 2–4 grams per day.

    Flower-Only. Lab-Tested. Backed by Patient Care.

    Made exclusively from premium cannabis flowers, High-Test FECO is third-party lab tested and completely solvent-free. Our care team supports each patient with a customized dosing strategy, ensuring comfort, efficacy, and long-term results.

    1:3 FECO is wonderful for autoimmune and inflammatory illness, early stage critical illness, and for use with preventative wellness. 

    Our 1:3 CBD-dominant FECO is excellent for the treatment of mild or moderate pain and unwanted symptoms. 1:3 FECO is perfect for daytime use and is an excellent option for patients looking for relief from moderate to mild pain management. Patients who still need to work find this 1:3 ratio of THC to CBD particularly effective in helping them remain productive and continue working throughout the day. 

    Due to the dominant ratio of CBD, our 1:3 FECO tends to be less narcotic than our other FECO blends. 1:3 FECO addresses inflammation in a powerful, meaningful way without the high psychoactive effects common with full THC or even 1:1 cannabis oil.

    King Harvest CBD FECO is a flower-only full extract derived from the “ACDC” strain. Additional strains this product uses include Girl Scout Cookies, Cotton Candy, GrandDaddy Purple, RuthlessOG & others. Learn more about other CBD ratios!
