Andro Side Effects (Androstenedione, Androstenediol)

Side Effects of Andro - Should You Worry? (2002)

We all know now that Andro is a precursor to testosterone and help you build muscle and strength. If you didn't already know, then you probably didn't read our articles on Prohormones. As effective it maybe, Androstenedione (Andro) has its many adverse side effects, and before you go out and buy some, you should fully understand what side effects of Andro you might experience.

Because Andro is a relatively new prohormone - on the market since only 1997 - it lacks thorough clinical studies that shows short term and long term Andro side effects. Nonetheless, following are some side effects of Androstenedione.

Andro Side Effects - Prohormone Lacks Thorough Studies

To date, no studies have show Androstenedione to have side effects on human subjects - this does not mean that Andro has no side effects. Some side effects of andro include:

  • Androstenedione supplementation may lead to elevated plasma estrogen concentration, which can lead to breast development in men, breast cancer, and pancreatic cancer
  • Using Androstenedione may lead to kidney and liver damage
  • You may also experience acne problems and oily skin - acne is associated with testosterone
  • It can lead to premature baldness in men
  • Taking Androstenedione can enlarge prostates, reduce sperm production and increase aggression
  • Can also lead to testicles shrinkage, infertility, loss of libido, and even impotence. **
  • Androstenedione can disrupt female menstrual cycles
  • Deepens voice and increase facial hair growth, and can also cause enlarged clitoris
  • Can lower HDL cholesterol (the good kind

** You may wonder why your this could happen. When the need for testosterone is satisfied, signal is sent to the hypothalamus and secretion is stopped. When you add prohormones in to your system, a similar effect takes place. So instead, your body doesn't get the chance to take its natural course of action.

This can be dealt with through cycling. Most information you read recommends 6 weeks on and 2 weeks off. However, it's in your best interest to take a equally long off period, or even longer off period. This gives your natural systems a chance to recover. I know a lot of people won't agree with me on this, but hey, it's just my 2 cents! In the end, it's still your choice. ;-)

Side note: It's not recommended for teenagers to use Andro, since alterations in hormone balance at a young age has adverse effects. If you're under 18, you should not use Androstenedione prohormones. Besides, at such a young age, you're full of raging hormones. ;-) I recommend you using creatine with whey protein - it works wonders. Read our articles on creatine and protein powder comparison.

The biggest drop in testosterone levels occur in your mid to late twenties, so this is a good time period to try out Andro if you're thinking about it. I sincerely hope that you fully understand the benefits and the possible side effects of Andro before purchasing.


Okay, so you might have a tough time deciding what to buy? There are just so many different types and brands... eesh... If you know what you want, follow the links above, if you're unsure what to get, you should read our Ergopharm 1 AD review.
