GenF20 HGH Spray Review - Does Retropin Work?

HGH Factor testers reported more energy and mental focus, sounder sleep, and an overall feeling of wellness and youthfulness. Some noticed a decrease in the number of wrinkles on their faces, and overall smoother, tighter skin (perhaps due to shed body fat?). 90% of our testers said they intended to continue using HGH Factor after the end of the trial. HGH Factor was the best formula we tested and we give it a MUST BUY rating.

The Utropin HGH formula proved to be effective. Our testers reported increases in energy and mental acuteness, sounder sleep, and a general feeling of well-being. Utropin HGH was the second most effective formulation we tested and therefore received a tentative buy rating - we recommend (with some reservations) this product if you cannot locate the top-rated product.

With Genf20 HGH, our testers reported a slight increase in energy and mental acuteness. When asked if they felt younger, generally testers said no, but said instead they felt better. Testers also reported sounder sleep. We gave Genf20 HGH a tentative buy rating based on its limited effectiveness.

The Sytropin HGH formula seemed to have absolutely no effect whatsoever on our testers. We're not certain as to the cause - Sytropin HGH has a similar formula to the other HGH sprays we tested. Perhaps the delivery system is flawed. Based on this information, Sytropin received a do not buy recommendation.

Like Sytropin, the Vital HGH formula seemed to have absolutely no effect on most of our testers but about 20% reported mild increases in energy, mental acuteness, and well-being. We aren't certain whether this is due to the Vital HGH formulation working for some people but not for others, or problems with quality control at the manufacturing level, or perhaps a placebo effect. At any rate, Vital HGH received a do not buy recommendation.

GenF20 HGH Spray Comparison

GenF20 HGH is another sublingual spray consisting of amino acids and "real HGH" created by genetically-altered bacteria. Our reviewers were troubled by GenF20's claim to provide "real HGH" – because HGH is FDA-regulated and cannot be sold without a prescription.

Despite our misgivings, GenF20 performed reasonably well for 20% our volunteers. They reported an increase in energy and alertness and general wellbeing. Overall, they reported feeling 5-7 years younger. The remaining 80%, however, reported no change whatsoever.

GenF20 Review

GenF20 performed fairly well – but for only 1/5 of our testers. This great difference might be due to differing body chemistries reacting to the GenF20 formula, or could be due to slipshod quality control during the manufacturing process. Some formulations are so delicate that they break down if left at room temperature, or if exposed to direct sunlight. We aren't sure why GenF20 didn't work for all our testers, so we can only speculate as to reasons.

Because GenF20 only worked for 20% of our testers, it earned a do not buy recommendation.
