I have been able to extract a very small amount of THCV from my plants so far. To date I have lost 36 pounds in 2.5 months. That is not all THCV, I am also doing keto, it is really just a helper to get me thru any rough spots to keep me on track. For that use, it is effective, no doubt.
I find that even in small quantities it immediately energizes, and removes all appetite. It burns off fast, and only is good for about 45-60 minutes. And I get that "overcaffeinated" feeling at about 5 minutes that lasts for 5 minutes. It does not intoxicate (me) in small quantities on its own.
If I am successful in producing in qty, I think a transdermal application is what I intend for dosing. We use DMSO and a silicone band-aid for that.
I have 2 extended family members with diabetes. Once I get this all nailed down, I will be working with them on an extremely small scale clinical trial to see what is real and not about these THCV claims. Based on what I have read and experienced, I am very encouraged.
