Because of the prohormone ban of 2009, testosterone boosters have had to come to rely on all-natural extracts like tribulus terrestris or longjack to get the job done. These plant extracts have shown great benefits but they still may not be as radically effective as the prohormones of yesteryear. Hoping to regain some of that forgone effectiveness, Primovar 100 has been formulated to exclude natural extracts and instead uses prohormone-like substances to deliver the anabolic results we’d like to see from a truly effective testosterone booster. Can it really be as effective as prohomones once were.

Ingredients

There are just two main ingredients in this formula. One is an amino acid variant called Acetyl-L-carnitine. This compound is L-carnitine bound to certain acids that make it more absorbable by the body and more effective. This ingredient is safe and has been shown to facilitate additional fatty acid utilization in the mitochondria. This in turn raises energy levels, burns fat, and helps muscle function. In all, Acetyl-L-carnitine is a great addition to a muscle building formula but it does nothing to actually raise testosterone.

The chief ingredient in this product is 1-Androstene-3b-ol, 17-one. Marketers would have you believe that it is similar to 1-androstenediol or 1-AD. Supposedly, it converts into testosterone in only a few quick steps. There has been little research conducted by experts to discover the effectiveness of this ingredient but from what we have been able to discover it has actually made it on to a few banned substances lists among certain sports circles. This might show that it is relatively effective but it could also mean that it causes side effects. In fact, we have seen some documentation claiming that it might be the cause of some cases of hair loss, lethargy, and an enlarged prostate.

Conclusion

With limited evidence to support this product and with the cloud of side effects hanging over its formula, we cannot recommend Primovar 100. Instead, try sticking with all-natural testosterone supplements. There are some that have been proven very effective and have plenty of clinical evidence to back them up.
