Blackstone Labs Chosen1 prohormone is chosen by destiny! Chosen1 is the prohormone 1-Andro.  1-Andro is related some of the most popular prohormones and steroids of all time.  The structure is closely related to the original 1 AD by Ergo Pharm, it is also distantly related to perhaps the most famous "PH" M1T or methyl-1-testosterone.   


The Active Ingredient

Chosen1 contains 1-Andro which is also known as 1-andostene-3b-ol-17-one or 1-DHEA.  The inclusion of the 1 in the name references the 1-ene structure of this Andro.


Legal Status

1-Andro is legal for sale as a nutritional supplement in the US.


Blackstone Labs Chosen1 Ingredients

The strength of this compound is enhanced by the addition of esters to the molecules.  It contains a blend of three different 1-DHEA esters:

  1. 1-androstene-3b-ol-17-one
  2. 1-androstene-3b-ol-17-one Decanoate
  3. 1-androstene-3b-ol 17-one Caprylate

This ester blend combined with a liposomal delivery complex makes for a better absorbed prohormone. 


Recommended Intake Dose Schedule

Blackstone Labs recommends two tablets per day.  This dose yields 130mg of their 1-andro blend.


Mechanism of Action

Chosen1 is a prohormone to 1-testosterone also known as dihydroboldenone.  1-DHEA is first converted to 1-androstenediol and 1-androstenedione via two separate enzymes in the liver.  Both compounds are then converted by the same enzymes to 1-Testosterone, a very anabolic isomer of testosterone.


Safety Considerations

Prohormones are very powerful supplements and all should consult a physician prior to use.
