Blackstone Labs Chosen 1 - 60 Tablets

Chosen 1 is a 1-DHEA product that was chosen by destiny and is one of the highest-powered proandros available anywhere on the market.  This is not a steroid; it is a precursor to a powerful testosterone derivative known as 1-testosterone.  1-testosterone is considered to be very potent.  It has an anabolic:androgenic ratio of 1:2.  This allows for drier gains and more aggression in the gym.  Chosen 1 is a derivative of DHT which means it cannot aromatize into estrogen.  Aesthetic side effects such as water retention and gynecomastia contain a low probability in you seeing these effects.  With Chosen 1 you’ll see increased muscle mass, no bloating, lean and dry gains, no estrogen conversion, and an increase in strength and recovery. 

1-Andro is the nomenclature for 1-Androstene 3b-ol, 17-one.  This compound will have little or no liver toxicity and studies indicate that 1-Andro has 2 times the anabolic potency of testosterone.

A Liposomal technology has been implemented in this formula to help stop conversion be interrupted by digestion.  Liposomal technology has been around for a long time in the medical field used as a carrier for drugs.  Liposomes are nutrient filled, double layered bubbles made from essential phospholipids and are used to deliver nutrients to cells throughout the body.  This technology offers maximized bioavailability with every dose.  As of today, this is the most bioavailable oral way to deliver nutrients.  In the past, 1-DHEA supplements were difficult to effectively get into the blood.  With the Liposomal technology, it makes for a very effective method of bypassing the destructive elements and aiding the 1-DHEA to be delivered to the cells.

Esters have been attached to this compound which creates an environment for sustained release of the 1-DHEA throughout the time of your use.  Esters control the release which helps eliminate the need to be dosed throughout the day on a manually timed schedule.  This makes it great for a simple AM/PM dosing schedule so you don’t have to set any alarms throughout the day and you can obtain optimal results.

Chosen1 is non-methylated and does not affect the liver.  Chosen1 does not harm the liver function in any way because the liver contains the necessary enzyme needed to convert 1-DHEA into 1-testosterone.  This is a serious product for serious bodybuilders and athletes. 

Back in 2004 there were multiple anabolic precursors in nutritional supplements that were banned by the American government.  Some of them listed were the precursors of testosterone.  In the Anabolic Steroids Control Act, no steroids with a C17 carbonyl group are mentioned which makes 4-DHEA 100% legal. 


While taking Brutal 4ce, it is recommended to take an on-cycle support supplement to help protect the body from any harmful side effects and to help get the most out of Brutal 4ce.  Blackstone Labs Gear Support is an all in one body support that contains red clover extract.  Red clover extract contains an array of clinically proven health benefits which includes improving liver health.  Whether you’re an intense bodybuilder, athlete, or just an average person, everyone needs this ingredient.  This ingredient helps purify the blood by acting as a diuretic and helps clear the lungs of mucous, improve blood circulation, and help cleanse the liver.  The other main ingredients that make Gear Support helpful are NAC, hawthorne berry, saw palmetto, coenzyme q10, celery seed extract, and grape seed extract. 

How long should you use an on-cycle support?  The length should be for about 4-8 weeks.  You should take the on-cycle support supplement for the entirety of your Brutal 4ce cycle.  Even though Brutal 4ce is non-methylated, Gear Support will help counteract any issues that pertain to cholesterol levels, blood pressure, prostate health, and inflammation. 

PCT (Post Cycle Therapy)

After taking Brutal 4ce, it is recommended to take a PCT supplement to help ensure your body restores its natural test levels and eliminate any unwanted side effects at the end of a cycle.  A PCT supplement helps re-start natural testosterone production, reduce estrogen, regenerate liver cells, and help maintain lean muscle mass gains. 

PCT V is more complete than ever.  This is an ultimate PCT supplement that can be used as a natural testosterone booster as well as being used as an anti-cortisol, DHT, and estrogen blocking supplement.  PCT V is a revamped version of PCT IV.  This new formula now will contain NAC and Laxogenin.  With this being a natural testosterone booster, it’ll help increase your test levels.  As you age, your test levels can drop and contribute to moodiness, weight gain, loss of muscle mass, and diminished libido.  PCT V is also an anti-cortisol supplement meaning it’ll help prevent all the negative side effects that cortisol can cause which includes weight gain and obesity, immune system suppression, gastrointestinal problems, and many other things.

How long should you use a PCT?  You should begin taking a PCT the day after your Brutal 4ce cycle ends and should last for about 4 weeks.  If you skip a PCT, then it may take about 1-4 months for your natural testosterone levels to return back to normal.  During this time, most of your gains may be lost, you’ll notice a drop in your libido, and you may encounter other undesirable side effects.

  • From James T. Slater at 4/1/2016 1:59 PM
    • Does it cause high blood preasure.
    • It is a possible side effect of taking any type of prohormone or andro product. That is why we recommend adding Blackstone Labs Gear Support to your cycle, as this can help control blood pressure.
  • From Eric at 4/25/2016 9:32 PM
    • Will my penis stop working? And will it make my hair fall out even if i dont have a receding hairline
    • Hi Eric - Any 1-andro product like Chosen 1 should have almost no side effects in regards to libido and sexual function. As for hair loss, when taking any type of prohormone or andro, there is always a chance for this side effect, though 1-andro products usually have the least chance of it.
  • From Nader at 5/9/2016 1:37 PM
    • Do I need to take a PCT with Chosen 1?
    • Yes, Blackstone Labs recommends taking a PCT with Chosen 1. They recommend PCT V. This can not only help you keep the gains you have made, but can also help you get back to normal levels in the body once your cycle is completed.
  • From Bill R at 5/9/2016 1:37 PM
    • Can I stack Chosen 1 with anything else?
    • Yes, Chosen 1 can be stacked with quite a few different Blackstone Labs supplements. On this page we list the most popular stacks for this product depending on your overall goals.

  • From 1-ANDROBOLIC at 5/15/2016 3:28 PM
    • I have a question which product its better Chosen 1 o Super 1 andro my Goals are to get a little big
      This is how im planning to cycle

      Week 1-4
      1 andro o Chosen 1 (depending which you recommend ) 2 pill a day

      Cycle support 2 pills a day

      Week-4-5 PCT [since this 2 product doesn't convert to estrogen i will not be using a E Control]
    • If you are looking to put on more weight, stack 4 andro and 1 andro would be better for you. Most users of 1-andro are looking to cut, but keep muscle mass and strength up. 4-andro is for those trying to get bigger. So our recommendations would be:

      IML Super 1-Andro + IML Super 4-Andro followed by a PCT supplement such as Blackstone Labs PCT V or just take Super 4-Andro then follow up with a PCT supplement. Hope this helps!
  • From tomtheuber at 6/26/2016 2:01 AM
    • If I do not take gear support will my liver be affected? What about my heart? And what happened if I do not take PCT?
    • Chosen 1 is non-methylated so you won't have any issues with your liver. It can raise blood pressure, but not as bad as with the banned prohormones of the past. If you want to be extra safe, take Blackstone Labs Gear Support while taking it. As for the PCT, it's not 100% necessary, but can help you reduce cortisol, increase libido and keep more of the gains you have made while on it. We would recommend Blackstone Labs PCT V for that.
  • From Randy at 10/26/2016 10:07 AM
    • Can I or should I take the PCT during my cycle to help reduce side effects?
    • No, a PCT is only for post cycle. During your cycle you should take Blackstone Labs Gear Support. That will help reduce side effects when you are on Chosen 1.
  • From nawaf at 11/9/2016 1:27 PM
    • can i stack chosen1 with Hi-Tech Pharmaceuticals Anavar
    • Yes, you can add Chosen 1 to Anavar and get some really good results!
  • From dan at 11/23/2016 4:25 AM
    • Hi Can i stack eradicate with this during my cycle and then run the pct5 for 4 weeks as indicated on the bottle?

      does this cause complete shut down? considering ill run the recommended amount for 6 weeks PCT 5 alone will be fine? or is a stronger SERM needed.

      posting from Australia

    • Chosen1 will not cause complete shut down like prohormones of the past so I wouldn't worry about that. As for Eradicate, we would recommend running that along with PCT V post cycle only. And no, you do not need a SERM for this cycle. It's much milder than prohormones like Super DMZ or M-Sten.
  • From daniel at 11/29/2016 4:54 PM
    • hi guys

      going to take chosen 1 for 6 weeks along with gear support for the same time.

      then run eradicate and pct 5 at the same time for 4 weeks.

      do i run the pct for as long as ive run the cycle or just for 4 weeks which is recommended?

      thank you
    • No matter how long you take the Chosen 1 prohormone, you only have to take PCT V for 4 weeks. Longer than that is not needed. Hope this helps!
  • From Matt at 2/24/2017 12:18 AM
    • Is there anything I should stay away from on a chosen 1 and gear support cycle? Like heavy pre workouts , creatine, or alcohol? And is there anything I should push myself to do more? Such as more water and stuff like that.
    • No...this is a non-methylated prohormone, so no worries about any of that. Definitely drink more water, train harder, increase your clean calories and get more sleep are the most important things to see better results from Chosen 1.
  • From Matt at 2/28/2017 1:13 AM
    • How should I take chosen 1 and gear support? 2 capsules of chosen in the morning and 1 gear? Or is there a certain way I should spread them out?
    • With Gear Support, you should be taking 3 capsules per day minimum during your entire cycle. With Chosen 1 take one in the morning and one in the evening. All these can be taken with or without food.
  • From Jr. at 4/25/2017 3:54 AM
    • Will I still have hair loss if it take gear support?
    • While it can help, anytime you take any sort of prohormone or testosterone boosting supplement, you will have hair loss if you are prone to it.
  • From Mitchell at 6/11/2017 9:07 PM
    • Is it safe to use at 15?
    • This is not safe for anyone under 18 years of age.
  • From BP at 6/28/2017 11:52 AM
    • Has anyone encountered anything that you should stay away from while taking this? The other posts are quite dated and wanted to see if anyone found certain pre workouts/ supps don't mix well.

      Also, I'm in a wedding in two weeks and kinda skeptical about drinking while taking this. Does anyone have experience consuming alcohol while on this? Does it just dehydrate you more like others or harder side effects?
    • No, you should be ok to take any other products along with this. You can take fat burners, pre-workouts and proteins with no issues. As far as drinking, while this is non-methylated, so it's not harsh on the liver, whenever using products that increase testosterone you should not drink a lot, but one night should be no problem. If you are concerned about anything, it is best to speak with your doctor.
  • From Kai at 11/3/2017 6:12 PM
    • Hey guys.. I’m 19 and was wondering if it’s okay to take this product. I have a lot of research on it and have friends my age that have done multiple cycles. I know the side effects are low but am just being cautious. Thanks.
    • Prohormones are not recommended for anyone under 21 years of age.
  • From Kelz at 12/25/2017 1:05 PM
    • Is this product legal in the United States?
    • Yes, the Chosen 1 prohormone is legal in the United States. We would never sell anything illegal here.

Enjoyed using this prohormone. No side effects and gained about 6lbs over 4 weeks. I am now taking the Brutal 4ce as I am starting to bulk. Both great supps.

Now that the regular prohormones are gone, Chosen 1 was the first 1-andro product I decided to try. What I noticed was I was a lot harder and dryer looking. More vascular, which was a real good thing. My strength was definitely up, even though I was cutting. I didn't gain as muscle muscle as I expected, though it is tough to tell because I dropped 10lbs...but kept my same strength. At the end of my 4 weeks I was definitely happy with how I looked. For a cutting cycle, I would run this again no problem.

Started taking Chosen 1 about 6 weeks ago during my cutting cycle and it has been an excellent addition. I am down 10lbs, but strength is up. A lot more vascularity along with it. I have my vacation next week, and am running it up until the day we leave. This is the best I am going to look on vacation ever and I own a ton of my results to Blackstone Labs and Chosen 1. When I get back I plan on running Brutal 4ce to build up more muscle for the summer. I will report on those results as well.
