“Original Sin: Journey into Darkness” is a dietary supplement that appears to be designed for individuals aiming to enhance their physique and muscle mass without the use of anabolic steroids. This product falls into the non-steroidal muscle enhancers, which are supplements formulated to support muscle growth, strength, and improved body composition through various natural or synthetic compounds that do not include traditional steroids.


  • 2a,3a-epithio-17a-methyl-5a-androstan-17b-ol: At 10mg per serving, this compound is known in the bodybuilding community for its potential anabolic effects, which may include increased muscle mass and strength. It is often sought after for its purported ability to provide steroid-like gains without the legal and health risks associated with steroid use.


The manufacturer recommends taking 2 to 4 capsules daily (at different times of the day). EPI supplementation should last about 2-2.5 months for best results.


“Original Sin: Journey into Darkness” is tailored for those seeking muscle enhancement through non-steroidal means, featuring the compound 2a,3a-epithio-17a-methyl-5a-androstan-17b-ol, which boasts potential anabolic benefits. To maximize the efficacy of this supplement while prioritizing health and safety, a structured approach to dosing, cycling, post-cycle therapy (PCT), and on-cycle support is crucial. Here’s an optimal strategy for utilizing “Original Sin: Journey into Darkness”:

Dosing Protocol

Daily Dosage: The recommended serving size is one capsule per day. Due to the potency of the active ingredient, adherence to this dosage is crucial to avoid potential adverse effects.

Administration: Taking the capsule with a meal may enhance absorption and minimize gastrointestinal discomfort.

Cycling Protocol

Cycle Duration: A typical “Original Sin: Journey into Darkness” cycle should last 4 to 6 weeks. This timeframe is sufficient to observe significant gains in muscle mass and strength while minimizing the risk of side effects.

Cycle Break: A break of at least 4 to 6 weeks is recommended after completing a cycle. This off-cycle period allows the body to normalize and helps maintain the supplement’s effectiveness for future use.

Post-Cycle Therapy (PCT)

Necessity of PCT: Implementing a PCT following a cycle is essential to support the body’s natural hormonal balance and recovery, particularly after using potent compounds like 2a,3a-epithio-17a-methyl-5a-androstan-17b-ol.

PCT Duration: A standard PCT regimen should last four weeks, commencing immediately after the cycle concludes.

PCT Supplements: Essential components of a PCT include natural testosterone boosters and estrogen blockers to aid in restoring hormonal balance. Supplements such as Tribulus Terrestris, Ashwagandha, and Milk Thistle for liver support can be beneficial during this phase.

On-Cycle Support

Liver Protection: Given the methylated nature of the active ingredient, including liver support supplements during the cycle is advisable to protect liver health.

General Health Support: Supplementing with a high-quality multivitamin, ensuring adequate hydration, and maintaining a balanced diet rich in nutrients will support overall well-being and the efficacy of the prohormone.

Duration of Use and Breaks

Monitoring: It’s essential to closely monitor the body’s response to the supplement throughout the cycle. Adjustments should be made based on personal tolerance, goals, and observed effects.

Sustainability: To sustain the health and the supplement’s effectiveness, adhere to the recommended cycle durations and breaks and consider periodic health evaluations.

Warnings and Precautions

Consultation: Consulting with a healthcare professional before beginning any new supplement regimen is strongly advised, especially for individuals with pre-existing health conditions.

Observation for Side Effects: Stay vigilant for adverse reactions during your cycle. If severe side effects are experienced, discontinue use and seek medical advice.

By following these guidelines, users of “Original Sin: Journey into Darkness” can aim for muscle growth and enhanced performance in a responsible and health-conscious manner.
