There are many men who buy testosterone supplements on Amazon to see what kind of difference they are able to make. However, there is no clear evidence that testosterone supplements work better than placebo or that they even make a difference in performance. One thing is for sure, there are many people out there who just want to get a lot of testosterone. Unfortunately, they may not understand what they are getting. If you want to make sure your product will help with performance, it is important that you know exactly what you are taking. There are so many products on the market today, and the number of studies that support the effectiveness of these products is dwindling. We have already seen an explosion of these products, which makes it more important than ever that we know what is really working in order to help us improve our performance. For example, there is an article in the Journal of Sports Sciences entitled "Effect of Luteinizing Hormone (LH) Receptor Antagonist (Triclosan) and Adequate Luteinizing Hormone (A) Supplementation on Performance in the Men's 200m Freestyle and 200m Individual Sprint." The article was published in 2013 and states that the following effects were found with luteinizing hormone (LH) receptor antagonists, luteinizing hormone receptor agonists, and an equol group: "The effect of an equol supplement on performance in the 200m freestyle and individual sprint was not significantly different from the placebo group." The article further states that a luteinizing hormone agonist may be beneficial for certain athletes who may have a lower response to testosterone, so this is why it may be beneficial.
