A Solid Four-Star Product

Posted by HawaiianViking on Dec 27, 2012

I like Universal Nutrition's products in general and N1-T, Natural Testosterone Supplement is no exception. The formula seems thoughtfully designed, though I'm suspicious that the average user can expect "to nearly double testosterone", as the manufacturer claims. Tribulus (protodioscin) does mimic Luteinizing hormone (LH), which in turn stimulates Leydig cell production of testosterone in the testes. However, indipendent clinical trials of Tribulus and its effects on human testosterone have shown mixed results. Other (probably) effective ingredients include avena (avenacosides A & B) and "patented longjack (Eurypeptides)", though it's beyond me what "patented" longjack means. While I like this product, I give it four stars and not five because, to me, the price is a bit too high, and I'd also like to see a few other ingredients added to this formula, like Maca or Mucuna pruriens.

Less Fatigue

Posted by SoulFisher on Apr 08, 2016

I am new to testosterone supplements. I am on my third day of the bottle and I already noticed increased focus and less muscle fatigue in the gym.. maybe due to quicker recovery. My appetite has decreased except for back day and leg day I devour what's in front of me. If the affect keeps going this way I will definitely cycle it again through the year.
