You buy a pre-workout, try it, and it feels no different to the last tub you just finished. Nothing gives you that rush you so desperately crave anymore. Introducing BioTechUSA’s Black Blood CAF+.

In this review, we are going to examine the ingredient profile of Black Blood CAF+ as well as give you our thoughts.

Black Blood CAF+ is a powerful pre-workout that surprised even us. It has quite the repertoire of ingredients designed to provide an intense surge of energy along with potent vasodilation.

Black Blood CAF+ Ingredient Profile:


Caffeine is a staple in most pre-workouts because of its incredible ability to increase metabolic energy levels, reduce fatigue, and enhance cognitive focus. Caffeine reduces the absorption of adenosine by blocking the receptors, thereby reducing the effects of fatigue. Caffeine also stimulates the Central Nervous System (CNS) to increase metabolic activity, as well as enhance cognitive focus.


Beta-alanine reduces muscle fatigue thanks to its ability to buffer the build-up of lactic acid in muscle tissue. When we train, the body uses resources and produces waste material. One such material is lactic acid, which builds up and causes fiery pains, as well as tightening of the muscle tissue. Beta-alanine increases carnosine levels in the muscle tissue allowing you to train harder for longer, delaying the effects of lactic acid.


L-Citrulline is a vasodilator, meaning that it dilates the blood vessels within the body. This widening of blood vessels results in more blood, and by extension, water and other nutrients being carried to muscle tissue. Increased blood being pushed into the muscle tissue reduces the risk of muscle injury and assists in creating microscopic tears in the tissue, increasing the potential for muscle growth. Lastly, it gives you an incredible pump, making you look massive while you train.

L-Arginine Alpha Ketoglutarate:

L-Arginine is also a vasodilator but breaks down into citrulline. Arginine is a great way to get the raw profile of citrulline, further increasing the vasodilation effects of citrulline. L-Arginine provides the same benefits as L-Citrulline, but it is a cheaper method to obtain citrulline, as it is a rawer form. However, it is still an incredible addition and you can feel the difference between the two.

Our thoughts:

Black Blood CAF+ Formula = 8/10

The ingredient profile is excellent, with scientific research supporting all of these compounds. It is also simple, and often the simplest compounds are the most effective. This profile is a good combination of varying ingredients as they all work in synergy. We would have liked to see more citrulline/arginine but this is still an incredible pump-inducing compound with good, clean energy.

Black Blood CAF+ Taste = 9/10

The flavours of Black Blood are absolutely superb. There is currently Blueberry and Cola available, and the Blueberry has that slight hint of saltiness to it, exactly like a blueberry. The Cola variant is amazing, it isn’t too sweet so that you get sick of it, and tastes similar to Kola tonic with water, excellent for those with a sweet-tooth.

Black Blood CAF+ Price = 7/10

It is imported so you can expect it to be a little more expensive. Black Blood is extremely good value for money though, as you are getting 30 powerful servings of pre-workout, and you could even this 2-3 times a week to prevent the body from becoming too used to it, giving you roughly two months of pre-workout. And that taste, oh wow, it really makes up for the price.

Overall Rating = 8.5/10

Black Blood CAF+ is an incredible pre-workout with a balanced formula and an incredible taste. We would like to see a higher concentration of citrulline/arginine but you can always add your own.
