Barlowe's Herbal Elixirs proudly offers TK-40 Cissus Quadrangularis Extract, containing 20% 3-Ketosterone and 40% total Ketosterones. Cissus Quadrangularis has been a staple of Indian Ayurvedic Medicine for millenia. It is now available to athletes, bodybuilders and anyone else who wants to support joint and bone health. Cissus supports healthy muscles, bones and helps deliver nutrients to tendons. The Cissus Quadrangularis Certificate of Analysis (COA) for this particular batch is shown above. Its name in India, "asthisamharaka", translates as "that which prevents the destruction of bones". Cissus Quadrangularis has also been found to be quite useful in weight loss programs as it helps control appetite and normalizes the metabolism. It has strong analgesic and anti-inflammatory properties, and it helps protect the lining of the stomach. ***These vegetable-derived capsules (Vegan, Kosher and Halal certified) are filled on slow speed equipment and only pure, unadulterated herbal extract is contained in the capsules. There are no magnesium stearates, fillers, gelatin, silicates, gluten, corn, wheat, rice, yeast, starch, titanium dioxide, artificial colors, artificial flavors or preservatives. Capsules produced with high speed equipment in herbal and dietary supplement "factories" generally contain several other ingredients, including powdered lubricants called STEARATES (which can greatly diminish an herb or supplement's absorption into the body). Check their labels! Barlowe also still bottles his products in glass as he believes chemical vapors can vent from plastic containers and contaminate the contents and that glass is better for the environment.
