First off understand one thing, M-Drol is not actually a prohormone, that is just industry mumbo jumbo to avoid the fact that this is in fact an oral steroid.
My personal view on this is that these types of supplements have wicked side effects and should only be considered as a last resort after a person has perfected diet, exercise, routine, nutrient timing, natural supplements, protein and every other aspect of a very good training program. I can tell you from having seen these supplements up close and personal, that there are usually far more negatives then positives to them, they can cause severe insomnia, acne, hair growth/hair loss, male breast tissue development, etc. Quite frankly, the real stuff, testosterone, has fewer side effects, is cheaper and far more effective, the only downside is its not legal. Don't get me wrong, I am not suggesting that you go out and start using illegal steroids, I am simply trying to make the point that these supplements are over-hyped, overly expensive and have wicked side effects for the benefits.
This particular one may be effective, but you are going to need to plan for PCT, post cycle therapy, as this will shut down your natural testosterone production, and you may notice some temporary testicular atrophy (nuts shrinking), which will return to normal once you start your PCT products and get your bodies own testosterone production running again. Also you will need to take a product or two for liver protection as these methyl products can be extremely hard on the liver.
This product is not a toy bro, there are major changes in hormones and the impact is such that you will need several additional products to correct it once you're done using it.
Personally, IMHO, I am not sure its worth it.
Good luck man.
I hope this helps.
