Whats the difference between 4-ad and Androstenedione?

[YoungGuns20]

I was just curious, I bought these supplements that came with M1T, 4-derm, and Androstenedione?

androstenedione is now illegal to possess whoever sold it to you shouldnt have. Basically andro"dione started it all it was the first one they had found that converted to testosterone . But It is a really weak conversion rate assuming you inject it for 100% absorbtion only 5% of it gets turned into test. ANd on top of that a good % of it turns into estrogen right away. Now 4 ad is what the scientists came out with they tweaked androstendione and make its conversion stronger up to 15% and threw a diol version instead of a dione so it doesnt directly convert to estrogen first.
