Hands down, the Lock & Key extreme formula tincture has been my favorite go-to whole plant CBD tincture for at least the past 4 years. Suffering with early signs of MS and other autoimmune related issues, it is very difficult to find quality whole plant tinctures on the market that pack so many milligrams (134!) into 1 mL dropper. For optimal sublingual uptake, less liquid is better which works great with this formula. I also think it's a great way to add a CBD to personal care products such as moisturizers or conditioners. Overall, less is more here and this extreme potency tincture delivers every time.
