What is Colossal?

A decent product that is relying on flashy advertising and marketing gimmicks to over-hype the product produced by this Scottsdale, Arizona based company.  In fact, one thing that is very disturbing in their ads is an endorsement from a Dr. G Johnson MD. Why isn’t the doctor’s name given? Why isn't his area of specialty (i.e. urology) cited?  This endorsement with a doctor not fully identified seems odd. Many surveys commented on how peculiar this seemed. Putting this issue aside let’s look at the formula itself. Delivered in a capsule form, it is a nice mixture of herbs and ingredients that can help you improve your erection size, energy and vitality.  It’s a 1398mg per two capsules serving of 21 ingredients including Long Jack, L-Arginine and Maca Extract. Long Jack has been a compound that has really gained favor in the last few years due to some new findings. It has been shown to provide male enhancement benefits for some users. The company makes some pretty strong claims but the surveys we have received have indicated that increases were not quite at the 25% level, but improvements were noted. Colossal is a sound formula that can produce results better than average. GRADE D

What ingredients are in Colossal?

Colossal contains tribulus terresteris, yohimbe extract, niacin, epimedium sagitatum, avena sativa, maca root, potency wood, ginkgo biloba, saw palmetto, oat straw, ginseng, catuaba, nettle leaf, orchic substance, oyster shell, cayenne and pumpkin seed.

Do the ingredients in Colossal Work?

Yes they can for some, but not very effectively. Tribulus terresteris, a flower extract, failed to affect libido levels in males in numerous studies, including one study reported in the International Journal of Sport Nutrition and Exercise Metabolism. All of its "reported" effects come from claims made by Jeffrey Petermann, a "strongman" who claimed it boosted libido levels in the 1970's.

Is Colossal safe?

Not entirely. Maca root consumption can increase a person's risk for goiters, especially if combined with a low iodine diet. Although rare, tribulus terresteris may also cause gynecomastia, or an abnormal growth of breast tissue in males.


Colossal contains a couple of ingredients that may provide some natural male enhancement, with limited evidence showing gingko biloba may improve male enhancement. There simply isn't enough evidence proving it effectively provides male enhancement, however. We recommend using more effective male enhancement supplements instead, such as Longinexx or Zyrexin.
