Instant male enhancement including erection size, confidence, and stamina – this is the Sinrex promise. Like others before it, Sinrex claims to be the most effective male enhancement pill ever made. But is Sinrex really as good as advertised? Here’s what we think:

Claims and Components

Taken once or twice per day, Sinrex boasts of being a male enhancer and volume enhancer in one easy-to-use pill, promising to deliver stronger, larger, and harder erections, improved sexual stamina, increased semen volume, and intensified orgasms.

Sinrex’s dual action formula features 100% natural ingredients known to have male enhancement properties, namely Tribulus Terrestris, L-arginine, Siberian Ginseng, Cuscuta Seed, Epunendum Sagitum, Gingko Biloba, Hawthorn Berries, Inosine, Maca, and Saw Palmetto. These male enhancers work together to increase the flow of blood to your penis, stimulate libido, and help boost testosterone levels.

Other Sinrex ingredients include antioxidants – Green Tea Extract and Vitamin E – and other supplements, particularly Copper Chelate, Inosine, Omega-3 Fats, and Soy Protein. The antioxidants help remove disease-causing free radicals to help boost sperm production and support prostate health.

While these ingredients are not unique to Sinrex, the product claims to be backed by a “clinical study” conducted by a certain “Dr. Milkias.” However, the doctor’s credentials and the full transcript of the study are nowhere to be found…

The Good

  • Male enhancement formula helps increase both penis size and semen volume
  • Claims to be backed by a clinical study
  • Provides actual testimonials

The Bad

  • Does not include Yohimbe and Horny Goat Weed, which “dilutes” the formula
  • Does not include Zinc or Oyster Extract, which are known to increase sperm count
  • Incomplete data on clinical study and no doctor’s credentials
  • Inconsistencies in the Sinrex website

The Verdict

Sinrex has the makings of a quality male enhancement supplement but falls short in several aspects. Though it contains some ingredients that are not usually found in a typical male enhancement supplement, certain key ingredients that should have been included are missing. We appreciate the clinical study but we know that you’ll want to see the doctor’s credentials.
