Blackstone Labs Chosen1 has garnered attention in the fitness community as a potent prohormone supplement designed to support increases in muscle mass and strength. The product is based on a derivative of DHEA known as 1-DHEA (1-Andro), which is a precursor to testosterone and is esteemed for its capacity to influence anabolic processes within the body. Unlike traditional anabolic steroids, Chosen1 is marketed as a non-methylated prohormone, which implies a reduced risk of liver stress, and is legally available on the market.

Chosen1’s formulation suggests that it enhances lean muscle mass while minimizing water retention, leading to a more defined physique. Blackstone Labs presents the supplement as a solution for those seeking to amplify their muscle-building potential without the bloating commonly associated with other anabolic agents. The prohormone is also designed to optimize absorption and bioavailability, to enhance its effectiveness.

Key Takeaways

  • Chosen1 is a prohormone supplement that aims to enhance muscle mass and strength through its 1-DHEA content.
  • Marketed as a non-methylated compound, it poses a lower risk to liver health compared to methylated analogues.
  • The supplement’s designed bioavailability seeks to maximize gains and lean muscle development.

What Is Blackstone Labs Chosen1?

Blackstone labs chosen1 review

Blackstone Labs Chosen1 is marketed as a muscle-building supplement that encompasses a 1-DHEA blend designed to facilitate lean muscle gains. It is positioned within the category of prohormones, distinct from anabolic steroids.

Overview of Chosen1

Chosen1 contains 1-DHEA (1-Androsterone), a prohormone that ultimately aims to increase the body’s levels of 1-testosterone, a key testosterone derivative for muscle growth. This prohormone is presented as a legal alternative for individuals seeking muscle mass enhancement without engaging in the use of traditional anabolic steroids.

The Science Behind 1-DHEA

The compound 1-DHEA (1-Androsterone) is utilized for its potential to undergo enzymatic conversion within the body, resulting in an increased anabolic state. The transformation process entails 1-DHEA converting to 1-testosterone, influencing muscle strength and mass, while presumably evading conversion to estrogen. This characteristic is crucial as it reduces the possibility of experiencing estrogen-related side effects.

Prohormone vs. Anabolic Steroids

Prohormones like Chosen1 differ from anabolic steroids in their action mechanism and legal status. Prohormones do not directly add hormones to the body but may augment the levels of existing hormones through metabolic processes. Anabolic steroids, by contrast, introduce synthetic hormones, greatly altering hormonal balance. Moreover, substances like Chosen1 are legal and available for purchase as dietary supplements, a status not shared by many anabolic steroids which are controlled substances in many regions.

Benefits of Blackstone Labs Chosen1

In exploring the advantages of Blackstone Labs Chosen1, one can expect to encounter benefits that cater to elevating testosterone levels, enhancing muscle mass and strength, as well as refining overall physical performance.

Boosting Testosterone Levels

Blackstone Labs Chosen1 is linked to testosterone enhancement. The product is designed to optimize natural testosterone production, which in turn can contribute to reduced body fat. By facilitating a rise in 1-testosterone, users might experience an improvement in factors like libido and a decrease in body fat, specifically in regions like the abdomen.

Muscle Growth and Strength Gains

The supplement is purported to contribute to increased muscle mass and strength gains. As it supposedly does not convert to estrogen, individuals can anticipate a growth in lean muscle mass without the commonly associated bloating. This aspect can be particularly alluring for those aiming to achieve a more defined muscular physique.

Improved Physical Performance

Users may also encounter an improved physical performance, including boosts in power and strength. The product’s formula is conducive to enhancing recovery, which simplifies the ability to engage in frequent and intense training sessions necessary for continuous strength gains and muscle development. An increase in muscle mass is also noted, along with the potential for augmented strength and overall physical capabilities.

Understanding the Side Effects

Blackstone Labs Chosen1 Review

When evaluating the side effects of Blackstone Labs Chosen1, it’s essential to recognize the potential impact on hormonal balance, liver functionality, and physical manifestations, which may include various risks associated with prohormone supplementation.

Hormonal Fluctuations

Blackstone Labs Chosen1 is known to influence hormone levels. As a prohormone, it does not convert to estrogen, thus minimizing the risk of water retention and gynecomastia. However, users might still experience other hormonal side effects such as:

  • Decreased libido: A common issue that can arise with hormonal supplements.
  • Hair changes: This can range from hair loss, potentially leading to baldness, to increased body and facial hair.

Potential Liver Impact

Chosen1’s formulation may exert stress on the liver. Being a prohormone, users should be aware that:

  • Liver toxicity: Supplements of this nature can increase liver enzyme levels, indicating stress on the liver.
  • Liver disease risk: Prolonged use may elevate the risk of developing more serious liver conditions.

Monitoring liver health through regular blood work is recommended for anyone considering this supplement.

Physical Changes and Other Risks

Apart from hormonal and liver impacts, Chosen1 can lead to physical side effects which may include:

  • Acne: A possible reaction due to hormonal changes.
  • Testicle size: Some individuals report a reduction in testicle size as a side effect.
  • Blood pressure fluctuations: Users should be cautious as there might be an increase in blood pressure levels.

These side effects are important to consider and monitor while using Chosen1 or any similar supplements.

Dosage and Administration

When considering the use of Blackstone Labs Chosen1, it is essential to follow the recommended dosage and understand the importance of cycling and post cycle therapy (PCT) for optimal results and safety.

The recommended dosage for Chosen1 is one capsule per day. Users are often advised to split the dosage into two administrations—half in the morning and half in the evening—to ensure stable blood levels of the active ingredient, 1-DHEA.

Cycling and PCT Considerations

Users should typically cycle Chosen1 for a period of 4 to 8 weeks. After completing a cycle, post cycle therapy is necessary to help the body recover and maintain the gains achieved. A PCT typically includes supplements that aim to restore natural hormone levels and mitigate any potential side effects caused by hormonal imbalances. During the cycle, it is also advised to use cycle support supplements to protect and support organ health.

Special Considerations

When considering the inclusion of Blackstone Labs Chosen1 in one’s fitness regimen, there are several factors that should be taken into account:

  • Organ Health: Users should be aware that Chosen1, like other prohormones, can be harsh on the organs. Regular monitoring and a cautious approach are advised.
  • Scientific Research: Although Chosen1 is stated to increase muscle mass and strength, there is limited scientific study on its long-term effects, necessitating careful consideration and possibly consultation with a health professional.
  • Hormonal Effects:

    • It is claimed that Chosen1 does not convert testosterone into estrogen, thus potentially avoiding estrogen-related side effects.
    • However, the product could still suppress natural hormone levels, which may result in side effects such as low libido and energy.
  • Usage and Dosage: Adherence to recommended dosage is imperative. Overuse might increase the risk of adverse reactions, while underuse might render the product ineffective.
  • Potential Side Effects:
    Effect Description
    Aggression May increase aggression in the gym.
    Libido and Energy Low libido and energy levels are possible side effects.
    Muscle Gain Tends to promote lean muscle mass gain without fat.

Individuals considering Chosen1 should carefully evaluate these factors and potentially discuss them with a healthcare provider to ensure they are making an informed decision based on their personal health profile and fitness goals.

Maximizing Effectiveness of Chosen1

Achieving the full potential of Chosen1 by Blackstone Labs requires a strategic approach, focusing on its advanced delivery system, synergistic supplementation, as well as disciplined diet and exercise.

Liposomal Delivery System

Chosen1 utilizes a liposomal delivery system to enhance bioavailability and ensure more efficient absorption of its active components into the bloodstream. Liposomal technology involves encapsulating the active ingredients in a lipid layer which can result in a more sustained release into the body. Optimal results are seen when the supplement is taken consistently and as directed, capitalizing on this innovative means of delivery.

Combining with Other Supplements

To complement and maximize the effects of Chosen1, individuals can consider carefully combining it with other supplements. For example, stacking Chosen1 with a high-quality protein supplement could support muscle growth, while adding a multivitamin may assure all micronutrient needs are met for optimal body function.

  • Pre-Workout: To increase energy levels before hitting the gym.
  • BCAAs: For supporting muscle recovery post-exercise.
  • Protein: Essential for muscle repair and growth.

Diet and Exercise

Diet and exercise are foundational to the effectiveness of any supplement regime, including Chosen1. A balanced diet high in lean protein, complex carbohydrates, and healthy fats supports muscle growth and recovery. Meanwhile, a consistent gym routine with both resistance and cardiovascular training is critical for maximizing the supplement’s benefits.

  • Diet: Balanced macronutrients to fuel workouts and recovery.
  • Exercise: A mix of weightlifting and cardio for all-around fitness.

Comparing Chosen1 with Other Supplements

When evaluating Blackstone Labs’ Chosen1, it is vital to compare it with other supplements in its category to provide an understanding of its positioning in the market for muscle building supplements.

Chosen1 vs. Other Andros

Chosen1 by Blackstone Labs is a prohormone, specifically falling under the category of andros, with its active ingredient being 1-DHEA. Andros, short for androstenedione, are precursors to testosterone and are often marketed to enhance muscle growth and improve athletic performance. Chosen1 distinguishes itself with a liposomal delivery system purported to significantly increase absorption and bioavailability. In contrast, some other andro supplements may not have such advanced delivery systems, potentially leading to lower efficacy.

Chosen1 vs. SARMs

Selective Androgen Receptor Modulators (SARMs) are another category of products aimed at increasing muscle mass and performance. Unlike Chosen1 which converts into testosterone in the body, SARMs work by directly binding to androgen receptors. SARMs are typically noted for their ability to discriminate between anabolic and androgenic activities, which can lead to muscle growth with fewer side effects. Chosen1, on the other hand, as a prohormone, may result in a broader range of hormonal changes and potential side effects.

Side effects comparison:

  • Chosen1: May lead to natural testosterone suppression, affecting libido and energy levels.
  • SARMs: Generally fewer reported side effects, but long-term effects are not well-studied.

Natural Alternatives

For those seeking natural alternatives to hormone-based supplements like Chosen1, compounds such as Sapogenix come into play. Sapogenix is formulated with plant-based ingredients, including sapogenins derived from sources like red clover extract. Some natural supplements also include supportive ingredients for testosterone production and male health, such as NAC (N-acetylcysteine) and saw palmetto. These alternatives tend to be favored for having a lower risk of side effects and for supporting natural testosterone levels rather than introducing hormones or hormone precursors into the body.

When discussing the legal aspects of Blackstone Labs Chosen1, it’s crucial to note that it falls within the category of prohormone supplements, which are legal to purchase in the United States. However, buyers should confirm the legality within their specific jurisdiction, as regulations may vary.

Safety Concerns:

  • Blood Pressure: Users should monitor blood pressure since prohormones can potentially cause fluctuations.
  • Cholesterol Levels: Prohormones may impact cholesterol levels, necessitating periodic checks.
  • Estrogen Conversion: Chosen1 is marketed with claims to have minimal effect on estrogen levels, potentially reducing the risk of associated side effects.
  • DHT (Dihydrotestosterone): Information regarding Chosen1’s impact on DHT is not decisively provided; DHT is a consideration for users due to its powerful androgenic effects.


  • Age Limit: Should not be used by individuals under the age of 21.
  • Health Conditions: Those with pre-existing health conditions, especially liver, heart, or endocrine-related, must consult a healthcare provider before using.
  • Usage Duration: Usage recommendations vary, typically a 4-8 week cycle followed by post-cycle therapy to help maintain gains and hormonal balance.
  • Drug Testing: Athletes should be aware that some ingredients may be prohibited in competitive sports and can lead to positive drug tests.

Users should approach Blackstone Labs Chosen1 with a clear understanding of their health and the legalities in their region. Regular health monitoring and consulting with healthcare professionals is advisable. It is the user’s responsibility to use the product according to guidelines and within the boundaries of the law.

User Experiences and Testimonials

In the arena of physical enhancement, Blackstone Labs’ Chosen1 has been a topic of interest among bodybuilders and athletes seeking to improve their physique. Users generally report noticeable gains in muscle mass and strength within a short timeframe. They credit Chosen1 with its ability to enhance strength without significant fat gain, attributing these outcomes to the prohormone’s composition.

A selection of user testimonials highlights a range of experiences:

  • Muscle Gains: Users commonly mention a visible increase in lean muscle tissue, attributing it to the anabolic effects of Chosen1.
  • Strength Enhancement: Reports often note a considerable upturn in brute strength, allowing athletes to progress in their training regimens.
  • Fat Retention: A key positive noted is minimal fat gain in comparison to muscle mass increase, appreciated by those aiming for a chiseled appearance.

However, these experiences are not without mention of potential drawbacks:

  • Side Effects: Some users discuss experiences with low libido and energy, suggesting possible suppressive side effects after prolonged use.
  • Research Data: Individuals also express concerns about the lack of extensive studies on long-term effects, urging caution and recommending further research.

It is crucial to understand that individual experiences with supplements can vary. User testimonials can serve as a starting point, but they do not replace professional advice. Users are advised to approach such supplements with an understanding of potential risks and in consultation with a healthcare professional.

Common Questions Regarding Safety

The safety of Chosen1 is a concern for users considering its potent formulation. Chosen1 is a prohormone supplement, specifically a blend of 1-DHEA, which converts into a powerful anabolic compound in the body. Users should be aware that prohormones can be harsh on the liver and may have other side effects. It’s recommended to consult with a healthcare professional before starting any prohormone regimen.
