I was given a sample of Primeval Labs Mega Pre Black Sour Lemon Candy recently, while purchasing some products from Natural Body Inc. I have tried a few products from Primeval and enjoyed them. I also tried the Mega Pre White which is a similar formula but without stimulans.
This flavor was enjoyable as it tasted like a lemonhead candy. It had a nice sour tangy undertone. It was a bit grittier than I'm accustomed to as some of the ingredients aren't very soluble.
This product hit me like a brick wall and not in a good way. I got very anxious after about 20 minutes. My heart was racing and I couldn't focus. Because of this, I can't comment on the pump or endurance factor as my anxiety took over. Based on these reasons, I can't see myself purchasing a tub in the future.
