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.

Border Collie Approved: Easy to Clean, Durable, and Great Bounce
Size: Medium (2.5"), Style: Fetch Pack 2
These are the best balls out there for dogs. These fit great in the chuck-it ball launcher, which we need to wear out my border collie. They fit her mouth properly and, most importantly, do not absorb all the spit or water after a good rain. They are quick to clean off and have good weight so you can let them fly! Furthermore, they bounce well, which is perfect for my dog that likes to catch them on a bounce. The ball is a strong rubber, so should not be easy to chew up. I've used these for years, and the only time I've had to replace them is when one gets lost in the hay field. I highly suggest these as replacements for the common tennis balls.

Treats and plenty of ball throwing with these doggie toy
Size: Medium (2.5"), Style: Fetch Pack 1
I have actually purchased these twice already. I love the one that glows in the dark but it still got lost in my yard lol. My dog is a big breed half pitt/Labrador so she did chew through one of them already. I play ball with her every single day but I DO have to take them away from her because she will destroy them. They are great to add in treats as well, that was one of the my favorite things about them as well. They do last just if you have an over zealous chewer do not let them keep them for long periods of time. They are a good value for the price. Buy them your dog will love it!

My Female GSD loves
Size: Medium (2.5"), Style: Fetch Pack 1, Size: Medium (2.5"), Style: Fetch Pack 1
Shasta is my smallest. Six in December (2025) along with her brother. She’s 100 lbs and outside, completely ball driven see last picture. Don’t let the size (2.5”) of these Chuck-It balls deter you. If your larger Breed dog has any orthopedic issues, has already torn their ACL etc, one has arthritis but wants to play. This size is perfect! Shazzy was born with several ortho issues. I don’t throw balls distance but right to her. This size and lighter weight assure even when Shazzy is spazzy w excitement, she’ll catch the ball mid air. The green balls are softer, and glow in the dark. In summer we can play well past dusk and I can see them! Her personality shows in the pictures. Playing ball is part of her. These balls are just perfect for her situation. Somehow they disappear, she loves making baskets, puts them in my tractor bucket, or my gardening bucket..then get put in burn pile, trash etc. I keep replacing them because she’d look day and night if we actually ran out!! 🙏✝️👍🏼👍🏼

Finally a Toy My Pitbull Hasn’t Destroyed in 5 Minutes
Color: Blue+Red, Color: Blue+Red
I have a 65 lb pitbull who destroys most toys almost immediately, so I’m always skeptical when products claim to be “indestructible.” Most toys last maybe a few minutes in my house before pieces are everywhere. These have actually held up surprisingly well. The material feels durable and thick enough to handle really aggressive chewing, and so far my dog hasn’t been able to destroy them like he does with most other balls and squeaky toys. That alone makes these worth it to me. I also really like the size. They’re large enough that I don’t have to constantly worry about him accidentally swallowing them or choking while playing, which is a huge plus for bigger dogs. The squeaker inside also keeps him interested longer since he usually gets bored quickly with toys that don’t make noise or bounce around well. If you have a strong chewer or larger dog and you’re tired of replacing destroyed toys constantly, these are definitely worth trying.
