Andro Review - Andro Stack 850 Review and AST 4-Diol-250 Reviews

With so many brands and types of prohormones, what should you choose? If you already know what you want (need), then that's great! But if you're unsure of what you should be using, read on. You may find this review helpful. We're going to review two of the more popular prohormone products on the market right now: Andro Stack 850 from Optimum Nutrition, and AST's 4-Diol-250. Let's start with the Andro Stack 850 Review.

Andro Stack 850 Review

In short, Androstenedione (Andro) is a direct precursor to testosterone, and this is the basis for Andro Stack 850. It's called a "Stack" for a reason. Let's just take a quick peak see what's in Andro Stack 850:

Each Capsule Contains:
Androstenedione: 100mg
DHEA: 100mg
Tribulus Terrestris: 650mg

Ah, so you see, it contains 3 main ingredients. The first ingredient is Androstenedione. Other 2 ingredients are DHEA and Tribulus. With this in mind, Andro Stack 850 is built on the popular DHEA-Andro-Tribulus stack. Let's take a look each.

Androstenedione: Not much needs to be said here. I already have full article on Andro. In short, it 'helps' increase your testosterone levels. However, we don't care too much for Androstenedione. Find out why in our new Androstenedione research update article.

DHEA: Unlike Androstenedione and -diol, DHEA is two steps away from testosterone. It converts into either Androstenedione, or Androstenediol. DHEA is the most prevalent hormone produced by the adrenal glands. DHEA has been shown to help weight loss, and increase the level of testosterone.

Tribulus Terrestris: Tribulus is naturally extracted form the rhizomes and roots of the plant Tribulus terrestris. Tribulus is a "testosterone enhancer". It's completely different from DHEA and Androstenedione - it works by increasing the production of LH (luteinizing hormone), which helps natural production of testosterone. Tribulus Terrestris details here.

The combination of this stack has worked nicely for many people. Instead of buying DHEA, Tribulus, and Andro separately, Optimum Nutrition put them all together in Andro Stack 850. This can save you a lot of hassle dealing with just 1 supplement instead of 3, and at the same time you can save some money. Many users have had positive gains with Andro Stack 850.

AST 4-Diol-250 Review

Another popular prohormone is AST's 4-Diol-250. Simply, it's just 4-Androstenediol (also know as 4-AD) and the 250 means there's 250mg in each tablet. Simplicity matters. ;-) Most agree that 4-Androstenediol would be the best prohormone available. Simply because 4-diol is the most anabolic of the prohormones. Compared to Androstenedione, Androstenediol has a conversion rate of over 15%, almost triple that of -dione.

AST 4-Diol-250 is just that, 250mg of 4-Androstenediol in each tablet. Simple, yet effective.

Now, both products are user proven products that drives results. Which you choose is completely up to you; however, what has worked for others may NOT necessarily work for you. Before you elect to use these prohormones, you should fully understand what you're using and fully understand the possible side effects of using Andro.
