We use medical-grade, hypoallergenic USP-filtered MCT oil (medium-chain triglycerides derived from coconut). MCT oil offers light viscosity, a smooth injection profile, and a low risk of allergic reactions compared to traditional seed oils such as cottonseed or grapeseed.
💡 MCT oil is widely regarded as the premium carrier oil for injectable compounds due to its superior absorption and minimal irritation.
Yes. MCT oil is widely regarded as one of the safest and most tolerable carriers available, even for individuals who have experienced allergic reactions to seed oils. It's hypoallergenic and has an extremely low incidence of adverse reactions.
