Ready to get in your zone with the AndroSeries?

Just fill out the AndroStat, and get linked to the AndroStacker to start building your AndroSeries stack. Your testosterone level will be automatically filled in, or if you already tested you can link back to the androstat from your email.

We've taken the "testosterone equivalent" values of our AndroSeries products and built them into the AndroStacker program. This allows you to build a stack of AndroSeries products and see the benefits, side-effects and "androgen zone" — so you can make sure you are taking the optimal dose for your custom goals with minimal side-effects.

Avoid Carbs and Stimulate Amino Acids Uptake

best post workout mealFebruary 19th. 2010 – You’ve probably heard that eating a high carbohydrate meal after training is better than a low carb meal. However, this may not be the case. Keeping post-exercise carbohydrate consumption low can prolong the nutrient uptake window created from training (via increased insulin sensitivity). (1) This is because training increases the muscle cells demand for nutrients, including amino acids, for repair and sugars to replace muscle glycogen.

The resulting increase in insulin sensitivity after exercise enhances the flow of nutrients to the muscle cells in need, as well as increases the use of fat as an energy source since sugars are not available. As glycogen stores fill up, however, the cells ability to take up amino acids (for growth) and fat (for fuel) will decrease.

The idea behind the high carb theory is that when you exercise, you use up muscle glycogen. The most efficient way to replenish your glycogen stores is through carbohydrate intake. If your training frequency has you exercising several times a day or every few hours, you’ll need too replace your energy stores more quickly to prepare your body for the next workout, and eating more carbs post exercise will help. If, on the other hand, you train once per day or several times a week and are more concerned with body composition, a carbohydrate restricted eating approach may prove more effective.

Insulin Sensitivity Affects Testosterone Levels in the Body

Insulin sensitivity affects testosterone levels in the bodyJanuary 7th, 2010 – Research has shown that people with type II diabetes and metabolic syndrome (i.e. insulin resistance) have significantly lower testosterone levels than regular men. (1,2) Insulin resistance is basically a condition where the insulin created by the body is insufficient to drive nutrients into the muscle and fat cells. This stems from having chronically elevated blood insulin levels.

Under constant stimulation from insulin, cellĂ­s become less sensitive to its effects, requiring more and more insulin to get nutrients into the cells. Therefore, anything which drives up blood sugar – like sugar, rice, pasta, beer, carbs of all kinds – and thus insulin levels can lead to a reduction in insulin sensitivity. Reduced insulin sensitivity equals lower testosterone levels.
