Product Specifications Table

Why Choose Supertest 375?

• Hybrid Ester Technology: Unlike single-ester products, Supertest 375 contains a mix of Propionate (fast), Enanthate/Cypionate (medium), and Decanoate (long) esters. This ensures you feel the effects within hours, but remain in an anabolic state for weeks.

• Superior Nitrogen Retention: Testosterone is the king of muscle building. This blend significantly increases nitrogen levels in the muscles, leading to faster tissue repair and massive growth.

• Reduced Injection Volume: Thanks to the high 375 mg/ml density, you can reach your weekly goals (e.g., 750 mg) using only 2 ml of oil, reducing the frequency of injections.

• Enhanced Recovery: Experience a dramatic decrease in downtime between grueling training sessions.

Dosage & Cycle Protocol

Critical Management & Safety

Due to its extreme potency, Supertest 375 requires careful management:

• Estrogen Control: High testosterone levels lead to aromatization. To prevent water retention and Gynecomastia, the use of Arimidex or Aromasin is mandatory.

• PIP (Post Injection Pain): High-concentration blends can sometimes cause slight soreness at the injection site.

• Natural Suppression: This product will stop natural testosterone production. A structured Post Cycle Therapy (PCT) is required starting 14-21 days after the last shot.

Frequently Asked Questions (FAQ)

1. Why is the concentration 375 mg instead of the standard 250 mg?

Supertest 375 is designed for advanced bodybuilders who require higher dosages. The higher concentration allows the user to inject less oil while receiving more active hormones, making it more efficient for heavy bulking cycles.

2. How many milliliters (ml) are in one vial?

Each vial contains 10 ml of sterile oil. Since the concentration is 375 mg/ml, one vial provides a total of 3,750 mg of testosterone.

3. Can I use Supertest 375 for my first cycle?

It is generally not recommended for beginners. The high concentration and the presence of multiple esters make it harder to manage side effects if you are inexperienced. Beginners should start with a single-ester testosterone like Enanthate.

4. When does the "kick-in" happen?

Because it contains short-acting esters, many users report increased energy, libido, and "pump" within the first 48 hours. However, the full muscle-building effects of the longer esters usually peak around week 3 or 4.

5. Is this product in tablet form?

No. Supertest 375 is an injectable oily solution. Testosterone is most effective and safest for the liver when administered via intramuscular injection.
