Multi-form 1-DHEA to help you get dry, lean gains and a harder look

Blackstone Labs Chosen1 is a straightforward prohormone built for one thing: giving you 1-DHEA precursors that turn into 1-testosterone. That's a non-aromatizing androgen—meaning it doesn't convert to estrogen—which helps with dry lean muscle, a harder look, and recomp where you build while staying lean. Don't think of this like a regular pre-workout or test booster. The setup is simple on purpose: no herbs, aminos, or weak extras—just a focused 1-DHEA blend with different forms to help with how it absorbs and releases.

Each tablet has 65 mg of the 1-DHEA blend, and folks usually take 1 tablet twice a day for 130 mg total. The ingredients are 1-androstene-3b-ol,17-one, 1-androstene-3b-ol,17-one undecanoate, and 1-androstene-3b-ol,17-one caprylate. 1-DHEA is a precursor that, after your body processes it, boosts 1-testosterone levels—not regular testosterone. That's key because 1-testosterone won't turn into estrogen, so you get those dry gains instead of water weight.

On dosing, 130 mg a day is in the ballpark of what people use for 1-DHEA stuff, though there's not a ton of big studies like with creatine. It's more about the logic and what users report. Adding undecanoate and caprylate forms is about tweaking how it gets into your system, potentially making it smoother.

Key Highlights

  • 65 mg 1-DHEA blend per tablet—everything here is about 1-androstene-3b-ol,17-one and its two ester versions, no filler junk diluting it. This makes Chosen1 a solid hormone-support pick focused on turning into 1-testosterone for dry, non-bloated muscle help.
  • 130 mg total daily at 2 tablets—this is a real dose you see in straight 1-DHEA products. It's legit enough to matter, but remember, your training and food are what make it shine, not some magic pill vibe.
  • Three forms of 1-DHEA—the main one plus undecanoate and caprylate. Esters like these can change how it absorbs and lasts, so it's smarter than just one basic form in a pill.
  • Made for dry gains—1-DHEA heads toward 1-testosterone, which skips estrogen conversion. Users pick this for lean muscle and hardness without chasing water-filled size.
  • No stimulants here—Chosen1 doesn't use caffeine or hype stuff to fake a buzz. It's about real progress in your physique and strength over weeks, not a quick hit.
  • Keeps it simple—lots of products in this space hide weak doses behind long lists. Chosen1 puts the spotlight right on the prohormone actives, no pretending it's a basic gym supp.
  • Blend total is clear at 65 mg per tablet—better than totally hidden props. Downside is you don't get exact splits for each form, so it's not fully open book.
  • Undecanoate ester hints at longer release—it's used to make things more fat-soluble and change body handling. Gives the formula a thought-out edge over plain 1-DHEA tabs.

Who Is This For?

  • Intermediate bodybuilders in lean-gain mode wanting harder, drier changes over fast weight ups. Chosen1's 1-DHEA blend targets 1-testosterone, great for density, recomp, and skipping that watery estrogen look.
  • Vets cutting fat but holding or building strength. Non-estrogen 1-DHEA fits comp phases where you want a dry finish and performance that matches the mirror.
  • Off-season competitors tracking everything tight. This shines when basics are nailed and you expect build-up effects, not instant wins.
  • Advanced gym rats who've done creatine, protein, pre-workouts and now eye hormone support. The clean 1-DHEA focus beats long lists of extras.
  • Folks after a prohormone without estrogen mass. 1-DHEA to 1-testosterone means harder looks over water-driven fullness.
  • Guys on 6-8 week hypertrophy blocks with solid habits. Effects build slow, so it suits consistent users who track recovery and plan post-cycle.

How to Use

Common setup for Blackstone Labs Chosen1 is 1 tablet twice daily for 130 mg of the 1-DHEA blend. As a prohormone, go for steady timing over gym-specific; same times each day beats random use. Take with a meal that has some fat— these actives like that for better uptake than on empty. If you're new to this, stick to the label and ease in over a few days. No stims mean no worries with coffee or pre-workouts, but manage overall cycle load smart. Avoid mixing with other prohormones, SARMs, or hormone actives unless you've got a plan for the total impact. Team it with creatine, protein, and real training instead of hoping it fixes bad habits. Run it in a set cycle with post-plan ready. Keep it cool and dry to maintain the tabs.

What to Expect

First 0-30 minutes: probably nothing, and that's fine—it's not a stim or pump chaser. No buzz, no tingles, no rush. Days 1-7: focus on steady dosing and watch how you feel in workouts, recovery, and any hormone tweaks. Weeks 2-3: start seeing the real deal, like a harder look, better drive, and small strength bumps over big weight gains. Weeks 3-4: things get noticeable—denser muscles, drier vibe, and lean support if your diet and lifts are on point. After that, it's all about keeping it going. Judge this over a full cycle, not one session.

Frequently Asked Questions

What is the active ingredient in Blackstone Labs Chosen1?

The verified active formula is a 1-DHEA blend at 65 mg per tablet. That blend contains 1-androstene-3b-ol,17-one, 1-androstene-3b-ol,17-one undecanoate, and 1-androstene-3b-ol,17-one caprylate.

How much Chosen1 do most users take per day?

The commonly referenced label protocol is 1 tablet twice daily, which provides 130 mg total 1-DHEA blend per day. Because this is a cumulative hormone-support formula, consistency matters more than taking it only around workouts.

Is Blackstone Labs Chosen1 a pre-workout?

No. Chosen1 contains no confirmed caffeine or classic pre-workout ingredients like citrulline, beta-alanine, or tyrosine. It is a prohormone-style product built around 1-DHEA for hormonal and physique-oriented support over time.

What does 1-DHEA do in this formula?

1-DHEA is a precursor intended to convert downstream into 1-testosterone, an androgen valued for lean, dry physique support. Users typically choose this pathway when they want hardness and recomposition support rather than estrogen-related water retention.

Why are there three forms of 1-DHEA in Chosen1?

Blackstone Labs uses the parent 1-DHEA compound alongside undecanoate and caprylate forms to create a more engineered delivery profile. The idea is to influence absorption and release characteristics instead of relying on only one version of the active.

How quickly do you feel Chosen1 working?

You generally do not ‘feel’ Chosen1 immediately because it is not a stimulant. Most users evaluate it over 2 to 4 weeks based on gym performance, muscular hardness, body composition changes, and overall lean-mass support.

Is Chosen1 fully transparent with its dosing?

Partially. The product discloses a total 1-DHEA blend of 65 mg per tablet, but it does not break out the individual milligram amount of each of the three forms. That means you know the total active dose, but not the exact ratio inside the blend.

Should beginners use Blackstone Labs Chosen1?

No, this is not a beginner-level supplement. Because it is a hormone-support/prohormone product, it is better reserved for advanced users who already understand cycle planning, side-effect monitoring, and post-cycle considerations.

Can I stack Chosen1 with creatine and protein?

Yes, that is a logical stack. Creatine monohydrate supports phosphocreatine recycling for strength and training volume, while protein supports the substrate side of muscle repair and growth—both complement the anabolic intent of a 1-DHEA cycle.

Does Chosen1 convert to estrogen?

The appeal of the 1-DHEA pathway is that it converts toward 1-testosterone, which does not aromatize to estrogen. That is why users often select it for drier gains and a harder appearance rather than a softer, water-retentive look.

Solid banana clips
Size: 5 Pack, Pattern Name: Banana Plugs
Ah yes, I used these solid banana plugs to convert my wires. It’s pretty easy to set up once the wire housing has been stripped and really cleans things up nicely. I haven’t had any discernable hissing, noise problems, or connection issues.

Get the right wire guage
Size: 1 Count (Pack of 1), Pattern Name: Banana Plugs
I rate the banana plugs themselves 4 stars. They are everything I expected and work as advertised. It's the experience of assembly that I rate three stars. The way these work is -- you strip off the outer insullation of your wire and separate the two leads (positive and negative). Then you strip some length of insulation off the end of one of your leads, you unscrew the banana plug so that it separates into its respective base (lower) and contact (upper) halves, you slip the wire up through the base, you flare the copper strands of the wire and fold the individual strands over the very top of the base (about 1/16 of an inch) (taking care not to extend the strands over the threaded barrel of the base), then you screw the upper contact onto the lower base and voila, banana plug / wire assembly. It's not as complicated as it sounds. Go to the Monoprice website and watch their excellent instructional video. Here's the thing though. While the assembly is not complicated, it is tricky, and if you don't get your proportions right the first or second or third time, you'll have to do it over. Fist of all, if your wire guage is relatively thin, like my 16-guage speaker wire, you'll find that the entire wire, insullation and all, will slip right through the base of the plug without butting up against the bottom of the base. If this is the case, then the wire is left to sort of flop around inside the plug and that has a kind of unfinished, amateur look and feel to it, whereas if the wire butts up against the bottom of the base, it has a solid, one-piece professional look. So, to my mind, there's a sweet-spot for wire guage that works best with this plug -- not too thin and not too thick. And since Monoprice has debunked the thicker-is-better myth (the quality of the copper is the real determinant), then you should feel free to get the wire guage that fits the plug. Next -- and here's where it gets tricky -- once your copper extends beyond the top of the base, you'll need to limit this extension to about a sixteenth (no greatrer than a fourth) of an inch. Then you very delicately flare out the individual strands, in a 360- degree arc, and fold the strands over the top of the base. This takes a fair degree of manual dexterity, especially if the wire is "floating" inside the base and its travel is not stopped where the insullation meets the base. You'll have to hold the wire and base steady in the fingers of one hand, then flare out the wire strands with either your fingers or a suitable object (the working end of a ball-point pen worked for me) with the other hand. This one-sixteenth measure is important. If you extend wire strands beyond the top and over the threads of the base, you'll find that screwing the contact end onto the base is impossible and you'll need to start over. One or two strands is OK and almost unavoidable. In that case the screwing will catch but if you take a pair of pliers to it you can muscle through. By the way, you can avoid the whole mess by getting the open-screw type, which I'm sure will work just as well without any of the hassle of assembly. Like anything else, if you do it a few times to make the mistakes and learn the tricks, then it will become second nature, and if you've already done that, then my review might seem overly fussy. In that case feel free to leave comments to help other readers.

Wish they came with instructions...
They are cheap and work great. They plug right into my Pioneer vsx521 receiver and my Paradigm Atom monitor speakers. I wish they came with instructions, because it took me about 10 minutes to realize the bottom part unscrews in addition to the top part. Here are my instructions for installation: 1) Unscrew the bottom part of this connector (the thin metal underneath the red/black ring). 2) Make sure the Banana Plug (which may be loosely screwed into the top part of the connector) is fully tightened down 3) Strip your wire tips to 3/8 of an inch (or just slightly under) 4) Run the first newly stripped wire end through the bottom part you removed in step 1, such that the stripped end of the wire is entering through the flat end and exiting through the smaller threaded end. 5) Leave about 1/8 to 3/16 of an inch of stripped wire hanging past the exit hole. 6) As evenly spaced as possible, bend the over-hanging wire strands over the exit hole (all around it, like a hat). If done properly, the wire should not fall out if you give it a VERY GENTLE tug. 7) Screw the top metal part (with the actual banana plug) back onto the bottom part. It may be difficult if your stripped wire is hanging too low. I've used a pair of pliers to grip the bottom part of the connector while I twist the banana plug side with my hand. If done correctly, you should be able to put a lot of tension between the wire and connector without removing/damaging it. UPDATE: I just recently helped my dad install his 5.1 system without these... it sucked... This item (5 pairs of them in this case) and a good wire stripper can save you alot of pain (both physical and mental). The connectors on the back of his receiver are the kind where bare wire comes in from the side and then the connectors screw down (with a banana plug hole in the center which is where this product would come into play). I felt like a surgeon trying to get a bare wire end into the little slot, and then holding it there while I tighten the connector which is almost impossible since they are so close together... GET THESE!

'Monoprice' = Worst stereo banana plugs on T-H-E market.
Size: 5 Pack, Pattern Name: Banana Plugs
The absolute WORST in stereo banana plugs - HANDS DOWN. After installing stereos and components for over 30 years, I'd say I'm experienced. These banana plugs fail at EVERY part of the design. Allow me to explain... 1) Starting with the tips, they are loose off the bat and fit LOOSELY in either the stereo input studs or speaker input studs by their 'girth'. They do not firmly seat in any plug and for this setup, I'm using a nearly $2K setup all together. They 'rock' back and forth (when inserted) and thus create a non-permanent connection, again, seriously making these utter junk. I've seen some items you can get by with over the years, but these aren't even rock bottom. They are unusable! 2) Next, the banana plugs themselves comes as three pieces. No non loosening o-ring seal but a plastic colored want-to-be imitation for positive and negative notation. Why do these stupid things come in three pieces? - I simply can't tell you why. I do know they serve no specific piece to solving the puzzle of installation so why do they come in three pieces...? My speculation is they are cheap china knockoffs. 3) The 'way' in which you normally install the trimmed wiring internally with the 'two-piece' design permits you to firmly CRIMP and hold the unsheathed wiring; but these do not. The overlap/overlay of the exposed wiring can only be about 2/16's of an inch thus not much to create a proper connection with. This single fact eliminates these plugs as even worthwhile component add ons; period. If you can't achieve a good ground/wiring connection, these are a defeated purpose... 4) Because of the design of these, they have no room to crimp and screw on the cable so your forced to nearly break your fingers in an attempt to get the unsheathed wire to overlay the internal threading and twist them on with all your might. This in effect breaks nearly every wire thread internally and then they breaks off inside. Absolute garbage. These are total pieces of non-quality junk that did nothing but makes me waste 30 minutes on attempting to get them securely on and another 25 to locate my Amazon account, find this product in my order and ALARM anyone else from making the same mistake I made. Now, I find out I can't even get a return on these. Thanks Amazon. Thank you third party retailer. You just made me a very dissatisfied decade long customer.
