Blackstone Labs - Chosen1 - 60 Tablets

Blackstone Labs Chosen1 is a 1-DHEA blend built for the aggressive athlete looking to maximize lean gains but minimize fat gain. The formula contains three potent esters of 1-Androstene-3β-ol,17-one (1-DHEA) totaling 65mg per tablet, staggered for fast, medium, and slow release to keep 1-DHEA levels elevated throughout the day. 1-DHEA undergoes a two-step conversion process — first to 1-Androstenediol, then to 1-Testosterone, a powerful derivative of testosterone with an anabolic-to-androgenic ratio of 1:2. Because 1-DHEA is a DHT derivative rather than a testosterone-pathway compound, it does NOT aromatize to estrogen — meaning drier gains, minimal bloat, more aggression in the gym, and no water retention. Chosen1 uses liposomal delivery to achieve 99% bioavailability, helping the compound survive digestion intact and reach muscle tissue at maximum effectiveness. Non-methylated — not liver toxic. Take 1 tablet twice daily (morning and evening) with food. Do not exceed 2 tablets daily. Cycle 4-8 weeks (up to 8-12 weeks per some guidance), followed by a full 4-week PCT. Not for women. Not for persons under 18.†

Three Esters, One Steady Release Curve

Chosen1's 65mg 1-DHEA Blend is specifically split across three distinct esters of 1-Androstene-3β-ol,17-one — a formulation choice designed to provide sustained release all day long rather than a single sharp spike followed by rapid clearance. Each ester carries a different number of carbon atoms attached to the base compound, which affects how quickly esterase enzymes in the body cleave the ester bond and release the active 1-DHEA molecule. The fast-releasing ester provides quick onset, the medium ester bridges the gap, and the slow-releasing ester extends activity into the later hours — together ensuring elevated 1-DHEA levels are maintained throughout the day from just two daily doses, rather than requiring more frequent dosing to maintain consistent blood levels.†

1-DHEA → 1-Androstenediol → 1-Testosterone — The Conversion Pathway

1-DHEA undergoes a two-step enzymatic conversion process in the body: first converting to 1-Androstenediol, then converting to 1-Testosterone — a powerful derivative of testosterone. 1-Testosterone carries a documented anabolic-to-androgenic ratio of 1:2, meaning it delivers roughly twice the anabolic (muscle-building) activity relative to its androgenic (masculinizing) activity compared to testosterone's 1:1 reference ratio. This favorable ratio is the mechanistic basis for Chosen1's drier gains, reduced fat accumulation, and increased aggression positioning — more muscle-building signal without a proportional increase in the androgenic side effects that come with testosterone-pathway compounds.†

Why 1-DHEA Doesn't Aromatize — The DHT-Derivative Advantage

The single most important structural distinction in Chosen1's formula is that 1-DHEA is a derivative of DHT (dihydrotestosterone) rather than testosterone itself. Aromatase — the enzyme responsible for converting testosterone-pathway androgens into estrogen — cannot act on DHT-derivative compounds the way it acts on testosterone or testosterone-precursor molecules like 4-Andro. This structural quirk means Chosen1 cannot aromatize or convert to estrogen under any circumstance, eliminating the water retention, bloating, and gynecomastia risk that accompanies testosterone-pathway prohormones. This is why Chosen1 is specifically marketed as producing dry, hard, lean gains — the physique outcome is fundamentally different from a wet-bulking testosterone-precursor compound, even though both ultimately support muscle building through androgen receptor activation.†

Liposomal Delivery — 99% Bioavailability

Chosen1 employs Liposomal delivery — nutrient-filled, double-layered bubbles made from essential phospholipids that have been used in the medical field for decades as a drug delivery carrier — to yield a 1-DHEA supplement that's 99% bioavailable. This liposomal encapsulation protects the compound through the tortuous journey through the GI system, where standard oral tablets face significant first-pass hepatic degradation before their active compound can reach systemic circulation. By ensuring the powerful anabolic survives digestion largely intact, Chosen1's liposomal delivery is directly responsible for hitting muscle tissue with maximum effectiveness from each dose.†

Non-Methylated — Why Chosen1 Isn't Liver Toxic

Chosen1 is non-methylated and does not harm liver function, because the liver contains the necessary enzyme needed to convert 1-DHEA into 1-Testosterone naturally — the compound is processed through the liver's existing enzymatic machinery rather than requiring the methylation modification that made older-generation prohormones (pre-2014, DASCA-era) hepatotoxic. This is a meaningful safety distinction: methylated compounds resist first-pass liver metabolism at the cost of accumulating liver strain over a cycle, while Chosen1's non-methylated 1-DHEA, combined with its liposomal delivery bypass of much of that first-pass processing anyway, produces a substantially reduced liver burden compared to older prohormone designs.†

Frequently Asked Questions

1. How is Chosen1 different from Hi-Tech 1-Testosterone?
   Chosen1 is a milder option compared to 1-Testosterone. While 1-Testosterone is stronger and acts faster, Chosen1 uses three different esters of 1-Andro for a time-released effect, providing steadier results over time with potentially fewer side effects. Choose 1-Testosterone for a more aggressive, faster-acting cycle, or Chosen1 for a steadier, more sustained approach.†

2. Do I need PCT after a Chosen1 cycle?
   Yes. After a 4-8 week Chosen1 cycle, your hormones need support to restore natural testosterone production. Blackstone Labs PCT V is specifically designed to complement Chosen1, and should be started immediately post-cycle (or up to one week before cycle end for a smoother transition), continuing for a full 4 weeks. Neglecting PCT can lead to hormonal imbalance, delayed testosterone normalization, and potential loss of gains.†

3. Can Chosen1 be stacked with other prohormones?
   Chosen1 is commonly stacked with mass-building compounds like Brutal 4ce or with cutting-focused compounds like Primobolan for a comprehensive cycle. Consult Get Yok'd staff for a stacking recommendation based on your specific goals — bulking, cutting, or recomp.†

4. Will Chosen1 cause a positive drug test?
   Yes. Chosen1 contains steroid hormone compounds and will cause a positive result on athletic drug testing panels. Not for tested athletes.†

How to Take Blackstone Labs Chosen1

Take 1 tablet in the morning with food and 1 tablet in the evening with food. Do not exceed 2 tablets in any 24-hour period. Cycle for 4-8 weeks (one bottle lasts approximately 4 weeks at the standard dose). Begin a full 4-week PCT (Blackstone Labs PCT V or comparable) immediately following the cycle. On-cycle support (Blackstone Labs Gear Support) and liver support are not required but commonly used alongside this and any prohormone cycle. Not for women. Not for use by individuals under 18 years of age. If you are at risk for prostate or breast cancer, do not use this product. Discontinue use and call a physician immediately if you experience rapid heartbeat, dizziness, blurred vision, or other similar symptoms. This product contains steroid hormones that may cause increased facial and body hair and voice deepening. Consult a physician before use if you have or have a family history of any medical condition. California Prop 65 Warning applies.†
