Who Is Chosen 1 For?

The problem with conventional bulking is that in your effort to increase size and strength, you’re all but guaranteed to increase body fat too. Some of the genetically gifted out there might put on less fat than others, but the fact remains if you want to build more muscle, you’re stuck with added fat..

Not anymore. Now you have the choice to build as much lean mass as you want, without the added fat, with Chosen1. This revolutionary muscle building supplement is for the aggressive athlete looking to maximize lean gains but minimize fat gain. Chosen1 harnesses the power of 1-DHEA, a compound proven to boost size, strength, and aggression.

Chosen 1 Ingredients:

1-DHEA Blend (65mg) Chosen1 contains THREE potent forms of 1-DHEA (1 androstene-3b-ol,17-one, which provide sustained release all day long. This ensures you have elevated levels of this powerful muscle builder throughout the day. 1-DHEA undergoes a 2-step conversion process, first converting to 1-Androstenediol then converting to 1-testosterone, a powerful derivative of testosterone. The advantages to using 1-DHEA over any other muscle building supplement is that it does NOT aromatize to estrogen and touts an anabolic:androgenic ratio of 1:2, meaning drier gains, little fat accumulation, more aggression in the gym, and better performance in the bedroom! Chosen1 employs Liposomal delivery to yield a 1-DHEA supplement that’s 99% bioavailable, ensuring this powerful anabolic survives the tortuous journey through the GI system, hitting your muscles with maximum effectiveness. Increased size, decreased body fat, and better performance make the Chosen1 an easy choice!

What is 1-Andro?

Chosen 1 = 1-andro

1-Andro is also known as: 

  • 1-DHEA
  • 1-AD
  • 1-Androstenediol
  • 1-androstene-3b-ol-17-one
  • 3β-hydroxyandrost-1-en-17-one

These variants are all the same as some are "common" names and others are "chemical or molecular" names a scientist would use. We prefer 1-Andro:)


Here is the science + Video:

1-Andro is a legal prohormone that through a 2 step process it converts to the active steroid 1-Testosterone. What makes 1-Andro so great is that it converts to 1-testosterone, the hormone, not another precursor. “1-Testosterone” is more anabolic mg for mg than just the hormone “Testosterone.” 1-testosterone does not convert to DHT (estrogen) and makes for minimal water retention. (Unlike 4-andro that converts to Testosterone, but allows for possible DHT conversion) 1-Testosterone levels increased can benefit:


  • Accelerated Muscle Recovery* 
  • Does not Convert to DHT*
  • Minimal Water Retention*
  • Lean Muscle "Gains" aka hyptrophy (size) and strength*
  • Increase Protein Synthesis*
  • Reduce Muscle Fatigue *
  • Strength gains*
  • Increased sex drive & libido*
  • Higher Energy*
  • Overall mood*
  • Lets not hide why the *stars at the bottom of the screen. We say that to protect from the Karens that don't workout and expect magic so que: * "The Food and Drug Administration has not evaluated these statements.

What Blackstone Labs Prohromones the best great?


Liposomal Delivery System 

Blackstone labs is the only Liposomal Prohormone. Liposomal is used in pharmaceutical, medical drugs. Liposomal products are designed to achieve a 99% absorption rate, achieved through both a fat-soluble coating and water-soluble coating of the supplement to bypass the liver and be immediately shuttled into the bloodstream. Normally, oral supplements have to pass through the liver at least 3 times before actually entering the bloodstream; by the time that happens you're only utilizing 33% of the supplement.THIS IS SUPER IMPORTANT AND NOT SOME GIMMICK MOST 1-ANDRO SUPPLEMENTS ONLY GET ABSORBED 33%. Meaning you have to take 77% more that is just being WASTED. LIPOSOMAL ALLOWS FOR 99% ABSORPTION.

So why do people take just Chosen 1 over Brutal 4ce, or vice versa?

Brutal 4ce is a 4-andro meaning the greatest gains, but more water retention. Brutal 4ce converts to Testosterone while Chosen 1 converts to 1-testosterone. And if you read above you will see that 1-testosterone will = less water retention and no DHT conversion in comparison.  Brutal 4ce is great for bulking, and besides water weight, not fat. Some people want to be shredded for a bodybuilding competition so % of water matters to them. They would take a 1-andro, Chosen 1, to achieve such goals while having the lowest amount of water retention. 

Honestly, 1-andro + 4-andro work so great together so think about stacking the two!

How To Take Chosen 1?

Take 1 Tablet in the Am. Take 1 Tablet in the Afternoon.

Take everyday for 30 days  (4 Weeks) straight.

A "cycle" can be taken 4 to 12 Weeks.  

1 Bottle = 4 Weeks *Beginner*

2 Bottles = 8 Weeks *Amateur*

3 Bottles = 12 Weeks *Professional* 


So if you also want to turn a 4 week Cycle like an 8, a 8 like a 12, and 12 into a 16, you can also extended your gains by taking a PCT. Some competitors, as in people who sell these products too, will call 1 Bottle of Chosen 1 plus a PCT a “8 Week Stack”

Do I need a Post Cycle Therarpy (PCT)?

PCT'S is not required, but recommend. PCT's can extend the heighten hormone levels after a cycle and extend "gains" from your cycle. So say you took an 4 week cycle (1 bottle) and you "Felt great!, Happy with results as you came off cycle. How much more could I have gained if I took 8 weeks?" So sum up what a PCT benefits to you is: Your gains, extend+. The "+" meaning any possible side effect will be negated and as you continue to come off cycle, you make greater gains. Blackstone Labs makes the best PCT in the supplement word with a product called PCT-V.

Chosen 1 (1-andro) can be taken by it’s self for beginners looking to make some gains.
