There is very little user feedback on independent review sites and forums which doesn’t give us much confidence in the product..

Reported Side Effects

There have been unconfirmed reports of nausea and other stomach related issues

Available directly from the official website, also available on – you will pay $59.95 for a months supply..

Cash Back Guarantees

The makers do offer a 90 day cash back guarantee – only applying to one opened bottle – any other bottles would have to be returned intact to receive a refund.  You will not be refunded shipping costs and you may also be charged a small handling fee.

Our Verdict

Testosterone Gels have been the subject of some negative press recently with several reports of lawsuits issued against certain manufacturers relating to serious side effects..  this does not however include Prototype IV 33 AB.

The Manufacturers claims are certainly overhyped… not disclosing ingredient amounts concerns us, as the amounts of certain ingredients often determines the effectiveness of the product.  More worryingly still – they have also included Yohimbe Bark, which has in the past been linked to some serious side effects including possible heart problems.

The ingredients listed (the lack of dosage aside) are largely untested… hardly any of them have clinical backing to confirm their effectiveness in increasing testosterone levels.

Any testosterone boosting product worth taking should include good amounts of D-Aspartic Acid, Fenugreek, Magnesium, Vitamin D and Zinc.

If used in correct quantities a couple of the ingredients could help to increase libido, so for any man looking to boost sex drive it might be a good product to try.

Body Builders Would Probably Not benefit from Prototype IV 33 AB
