I want to post my personnel experience as a long time androgenic anabolic steroids user but most important of all I want to point out my convinction that testosterone is the best choice to try. Why do I have this idea? Personally I have been thinking that testosterone is the best hormone to use if you want to add mass, strenght, vascularity and to loose fat because is the most natural hormone we are used to handle. When we talk of chemical substance or hormone treatment therapy keep in mind that mimic nature is the best choice. Testosterone is produced by our body since we were born and it raise stably till we grow up to adulthood then it declines slowly. It is known for its anabolic effects but is less known for its important neurological activity http://www.sciencedaily.com/releases/2013/07/130726191522.htm
This neurological activity is produced by dihydrotestosterone, which is made by the action of the enzyme 5-alpha reductase (5-AR) that converts testosterone in DHT. In this case testosterone acts as a pro-hormone. Unfortunately Dihydrotestosterone has a bad reputation but most of it is a myth. I enclose this link to learn more about DHT: http://www.bodybuilding.com/fun/reform8.htm
Testosterone is also converted to estradiol, which produces an important function in our body, by aromatase enzyme in the fat cells. See this link: http://www.nih.gov/researchmatters/september2013/09232013testosterone.htm
Testosterone is more than just fuel for a sex machine. Low testosterone levels can also cause:
•Decreases in bone density, which can lead to osteoporosis
•Diminishing ability to concentrate, as well as irritability and depression
•Increases in body fat, particularly in the midsection where the buildup puts them at heightened risk for type 2 diabetes, heart disease, and certain cancers.
So testosterone is a fundamental hormone in our body and above all most of its role and function is made by its convertion in estradiol and DHT. When aas were produced in laboratory, scientists tried to alter chemical structure of testosterone to minimize convertion in estradiol and DHT and to maximize its anabolic role. But doing so we have lost most of its beneficial effects that are due to convertion in E and DHT since it acts as a pro-hormone.
After a bit of scientific studies let's talk about practise. I have been using aas for 20years by now. I used every substance sold on the market and year by year I have been convincing myself that testosterone is the best substance to use. Why? Because when i use testsosterone I feel stamina, strenght, energy, well being, sex appetite and other symptoms that no other substance produces and besides testosterone makes me feel stronger than ever. Moreover I noticed in all these years that when I use testosterone my body fat declines faster than I use aas. In fact as testosterone converts to DHT it stimulates nervous system and I think stimulates fat cells through its effects on nervous system that allows to get rid of fat quicker. Many aas converts to weak DHT, as Boldenone does, or do not convert at all.

"This is not a scientific statement and I am not a scientist but it is only my idea and conviction after many years of usage"

So I challenge all of you to make this experiment. Substitute your aas quote with testosterone and see what happens. Try to figure sensations, effects and results. For istance who uses 500mg of testosterone and 500mg of aas (deca, boldenone, primobolan etc) a week could substitute aas quote with further 500mg of testosterone and see its effects. In this case one should inject 1 gr of testossterone a week and see positive effects and side-effects.
Let me know your feedback and experience...thanks

P.S.. I used 1gr a week as an EXAMPLE...please do not take my challenge as a bible. To me it is your feedback important whatever dosage you have used. Let me know if,according to you, testosterone alone works better than testosterone mixed with aas. That's all
