Straight-up 1-DHEA blend for lean, dry muscle cycles

Blackstone Labs Chosen This 1 Stack is like their Chosen1 formula in a 60-tablet bottle. It's a prohormone product focused on 1-DHEA, not a mix of different hormones. The idea is simple: use 1-androstene-3b-ol,17-one in a few forms, like undecanoate and caprylate esters, to build a lean-mass vibe that leans toward 1-testosterone without estrogen fluff. In the gym, it's for chasing harder looks, better strength, and denser muscles when your training and eats are on point.

The main ingredient is 1-androstene-3b-ol,17-one, or 1-DHEA for short. It's a prohormone that aims for the 1-testosterone path. Unlike creatine or citrulline with tons of studies and set doses, 1-DHEA has less solid data on how much to take. That's key to know. The label shows a 65 mg prop blend per tablet, but it doesn't break down how much is base versus the ester forms. It's not about a quick stim feel. Over time, it should help with training output, muscle fullness, hardness, and recovery.

Those undecanoate and caprylate forms are just ester versions of the same thing. Esters change how the compound absorbs and releases—think better uptake. So Blackstone isn't throwing in random stuff; it's all about different ways to deliver the same precursor for a steady effect. That approach can work well from a formula angle, but

Key Highlights

  • All about 1-DHEA—this is a prohormone-style stack centered on 1-androstene-3b-ol,17-one, not some generic muscle mix. It keeps everything on one path instead of low-dosing a bunch of random ingredients.
  • Three ways to deliver it—the label has the base 1-DHEA plus undecanoate and caprylate forms. That's smart for mixing up absorption and keeping levels steady, not just dumping one raw version.
  • Made for lean gains—guys pick 1-DHEA for that hard, dry vibe and body recomp. It's not about fast bloating or huge scale jumps like some other stuff.
  • 60 tablets for easy dosing—if you're running a daily cycle, tablets beat powders or liquids for staying consistent. It's about routine, not a quick feel.
  • No stims here—forget caffeine or energy boosters. This is pure hormone support, so you can take it anytime without timing it to workouts.
  • Keeps it simple with one path—unlike multi-hormone stacks that muddle side effects, this sticks to 1-DHEA only.
  • Builds over time, not instant—don't expect a rush or pump right away. It's for weeks of better training, physique shifts, and comp changes.
  • Prop blend hides details—the 65 mg total doesn't show exact amounts per form. That's a downside; you can't compare to studies perfectly.

Who Is This For?

  • Intermediate bodybuilders in lean-gain mode chasing dry hardness over quick water gains. The 1-DHEA blend fits guys wanting that 1-test path, not a everything-in-one hormone mix.
  • Experienced lifters who know prohormone responses and like a clean single-path option. It narrows down to 1-androstene-3b-ol,17-one and esters.
  • Physique folks in offseason recomp where density, intensity, and steady lean mass beat big weight spikes. It's about dry gains, not wet bulk.
  • Guys who dig tablets over powders or multi-pills. One-tablet doses make daily routines easy for this cycle-focused supp.
  • Lifters building stacks with separate supports. Since it's just the hormone blend, it's for planning your own liver, on-cycle, and PCT stuff.
  • Advanced trainees who've maxed basics like creatine and pre's, now eyeing hormone boosts. This is targeted hormonal, not everyday nutrition.

How to Use

Follow the label exactly if you get what 1-DHEA involves. Not a stim, so take it at a consistent time daily; many go with meals, especially fatty ones, for easier swallow and uptake. Don't pile on other hormones right away—harder to spot issues. It's a tablet, so down with water, no crushing unless they say. Better with food if you're sensitive. Stack with basics like creatine, protein, and supports, not more prohormones unless planned. Cycle it, don't run forever, and line up PCT first. Store cool and dry, away from kids.

What to Expect

First 0-30 minutes: probably nothing, since it's no stim or pump product. No caffeine buzz, no tingles, no quick rush. Days 1-7: just get used to it, watch for appetite or energy shifts, keep training steady. Weeks 2-3: look for the good stuff like better gym sessions, recovery feels, weight trends, and muscle hardness. Weeks 3-4+: visuals kick in more with good eats, training, and sleep—aiming for that denser, drier look. Judge it over weeks, not one session.

Frequently Asked Questions

What is Blackstone Labs Chosen This 1 Stack actually made of?

The verified formula points to a Chosen1-style 1-DHEA blend containing 1 androstene-3b-ol,17-one plus 1 androstene-3b-ol,17-one undecanoate and caprylate. These are different forms of the same core hormonal precursor, included to support a 1-testosterone-oriented pathway.

How much 1-DHEA is in each tablet?

The closest verified label indicates a 65 mg proprietary blend per tablet, but the exact amount of each individual form is not disclosed. That means you know the total blend size, but not how much comes from the base compound versus the undecanoate and caprylate forms.

Will I feel this product right away like a pre-workout?

No. This is not a caffeine, pump, or nootropic product, so most users do not feel a noticeable acute effect on day one. It is designed for cumulative changes across weeks of consistent use, not an immediate gym rush.

Is this a good beginner supplement?

No, this is not beginner-friendly. A 1-DHEA-based formula belongs to a much more advanced category than creatine, protein, or pre-workout, and it requires a more informed approach to support supplementation and cycle planning.

What kind of results do people usually use this for?

Products in this category are typically chosen for lean mass gain, improved training output, physique recomposition, and a harder, drier look. The expected appeal is usually visual density and dry progress rather than fast watery weight gain.

Does this product contain caffeine or stimulants?

The verified active formula does not list caffeine or standard stimulant ingredients. Despite conflicting metadata, this should be understood as a hormone-support product rather than an energy product.

Should I take this with food or on an empty stomach?

Many users prefer taking tablet-based prohormone products with food, especially meals containing some fat, for comfort and practical absorption reasons. Since this formula does not rely on rapid pre-workout onset, consistency matters more than taking it fasted.

Can I stack this with creatine and protein?

Yes, that is a more logical stack than combining multiple hormonal products blindly. Creatine supports phosphocreatine replenishment and training performance, while protein helps provide the amino acid substrate needed to capitalize on harder training.

Do I need post-cycle support with a product like this?

Responsible users should plan cycle support and post-cycle support before starting any 1-DHEA-based formula. This product does not include those support ingredients within the tablet, so they need to be considered separately.

Is the formula fully transparent?

No. The active system is listed as a proprietary blend, so the total blend size is known but the individual milligram amounts of each 1-DHEA form are hidden. That is the biggest formulation limitation of this product.

Function is great, a bit breakable
Style: Classic, Size: 26in
This is probably the 3rd or 4th of this we've bought which reflects pros and cons--it is a great thrower, easy to use and great for keeping your hands clean with a dog who loves to play fetch! The con is that they're a bit brittle. We've broken a couple just smacking the plastic against a sidewalk, so you just have to be a little careful. Our puppy chewed on another one and destroyed it, so you might want to keep it out of the reach of your dogs when you're not using it!

Best toy EVER for a very active dog!
Style: Classic, Size: 26in
This is the best item I've purchased for my young Mini Schnauzer. He absolutely loves that I can now pitch the tennis ball quite a ways and he gets loads of running time. He begs for me to use this toy for him . . . he LOVES it! Easy on the arm as well!

Our dogs love it
Style: Classic, Size: 26in
On one of our trips to the dog park we saw someone using one of these with their dogs, it looked pretty neat and the ball flew so much farther than by hand. It wasn't very long before our dog got caught up in the excitement and joined the pack running after the tennis ball. Our dog stood with the rest of the dogs at the park staring at the ball in this launcher and waiting for the lady to throw it, once thrown the entire pack raced across the park after the ball,...they loved it! I decided to buy our own after watching and seeing how much fun they were having. This arrived a couple of days after I ordered it, and what struck me as funny was our dog recognized it as the toy from the dog park as soon as I pulled it out of the box. She couldn't wait to play. There is a small learning curve, but after a few trial throws I got the hang of it. This 26M launcher is a little large for me, it works but seems to work out better for my husband. I am going to order the smaller 18M size for myself. Both of our dogs had a great time, we had them running all over the place chasing after the ball. It was great being able to tire them out! With this launcher you can throw the ball farther and faster than you can by hand. Being able to scoop the ball up without having to touch it is a bonus, especially when the ball returns full of dirt and dog drool! This ball launcher can also be used with regular tennis balls too so if the ball that comes with the launcher gets lost it is easily replaced. Perfect toy for tiring out our dogs! *Update 9/24/16- I ordered the Junior 18M, it works so much better for me. The longer length of the 26M was starting to make my wrist sore, however my husband has had no issues. I'm 5'4" and my husband is 6'3" in case this info helps anyone make a decision on which one to buy. I know I went back and forth trying to figure out which one, which is why we now have two. ;)

If you were looking for a sign to buy this, here it is
Color: A) Small 2.5" Ball
If you are looking for a ball that can stand up next to a heavy, aggressive chewer.. this is a good choice. Our Pitbull literally destroyed any and every toy that she gets with the exception of one kind of kong ball. She tore through the kong Frisbees, any kind of squeaker toy, and the wobble wag giggle ball (she usually always ends up destroying these but it takes a few weeks. Today she beat her record and had her brand new ball destroyed within the first 30 minutes of us taking it out of the box). But, this ball she has not been able to destroy. I'd like to believe that the Kong ball she has and this ball are made of the same material. Because they are the only balls she can't ruin. And it's not because of a lack of trying. We have watched her sit there and chew with a side of her mouth for an hour or more, trying to make some kind of indention or tear in it and it just never happened. She loves to chew this thing, chase this thing, sleep with this thing. I most certainly recommend this ball. If it is I'ah proof then it is most certainly, 100% a durable ball and worth every penny

Chew King Supreme Chew Toy
Color: B) Medium 3" Ball
So far, freaking amazing. This ball is awesome. I have a 90 lb American Bulldog. Like other reviews. Lot of " indestructible balls" lasted minimum time. Not this one. She even took it to bed with her I bought the 3 inch ball, not the 4 inch ball. The 3 inch ball works amazingly for a large Dog. Yes the 4 inch would be better. So in my opinion, either ball would be fine. As others also said. This ball keeps a active Dog busy for hours. Love to play catch. Love frozen peanut butter in it. One last thing. The price is amazing. I don't see needing to buy another, unless it is lost, because this is made to last. We couldn't be happier.
