SD 50

Looking to increase muscle production? An increased sex drive? More energy? If so, you may like SD 50. According to the makers, it can “double your testosterone level in 60 days naturally with no drugs, no patches, and no injections.” Although this sounds amazing, keep in mind that the majority of testosterone supplements out there do not work (our research has shown that only 5-10% can have a significant impact)

Does SD 50 work? Can it significantly increase testosterone levels? In this review we’ll take you behind our research and analysis of SD 50.

In Depth Look at SD 50’s Ingredients

The manufacturers only disclose 1 ingredient that is in SD 50, 400 milligrams of tongkat ali. Tongkat ali, also known as Eurycoma Longifolia, is found in several testosterone supplements.

Can Tongkat Ali help increase production of testosterone?  Tongkat Ali  is a solid ingredient backed by several clinical studies to help boost testosterone levels:

  • An experiment conducted on mice found that eurycoma longifolia increased sperm count
  • A study conducted in Italy showed that tongkat ali increased the libido of the majority of users.
  • A study was published in the British Journal of Sports Medicine that showed that the lean body mass of the treatment group (taking ali) increased over 2 kilograms and that the increase in strength was 4% higher in the treatment group than the placebo group

Despite these studies, there are some potential drawbacks to tongkat ali. Most studies indicate only a mild effect. To get significant results, tongkat ali must be combined with other effective testosterone ingredients. There also have been rumors circulating the internet of fake tongkat ali.

Is SD 50 safe?

SD 50 is not associated with any serious side effects. Be sure to drink plenty of water in conjunction with the product.

Price and Guarantee Policy

One of the biggest cons about SD 50 is its high price. There are 2 purchase options- a 1 month supply for $105 plus shipping and handling or a 2 month supply for $147 plus shipping and handling. Either way, SD 50 is at least double the price of most testosterone supplements on the market. Considering it only contains 1 ingredient, which is found in many other alternatives, SD 50 is ridiculously expensive.

On the positive side there is a money back guarantee. From the SD 50 website:
We offer a 100% satisfaction, money-back guarantee. Email us within the first 90 days after purchase to claim the refund. This refund guarantee is only good for the first purchase. Refunds will not be issue for repeat purchases by the same customer or household. Refunds will be made back via the method originally used.”

Pretty solid guarantee.


SD 50 is a decent testosterone supplements but there are two big reasons I am wary of recommending it:

  1. It only contains 1 ingredient. Eurycoma longifolia (tongkat ali) is a solid ingredient, but it won’t give you dramatic results by itself. It needs to be combined with other effective ingredients.
  2. SD 50 is ridiculously expensive. SD 50 costs double the price of most of the top rated testosterone supplements.
