I've never tried that supplement but looking at it, it seems like a grift. There's no ingredients or amounts listed which is usually a bad sign for any supplement. Paying $90 for zinc, vitamin C, and rosehip which grows everywehere where I am seems rediculous. Lock n load is a gorilla mind product that clearly labels the ingredients and dosages on the website and bottle. The owner also has a few videos describing the recent formula changes. It is expensive, and I haven't tried it, but the other gorilla mind products I've tried were great.
Personally I think you'd be fine with 1-2g sunflower lecithin, 25mg zinc (I use citrate because it's well absorbed, widely available and cheap), drinking lots of water, and pineapple for taste if that's your bag. You can get into pygeum but personally it did nothing for me, and I had to order it online since nobody stocked it locally. Don't take the zinc if you already have a high zinc diet, and take it separate from copper since zinc blocks copper absorbtion. With a good enough diet you probably wont have to take any supplements. Don't spend dollars just to step over them to pick up pennies.
