What Is Testosterone Enanthate?

Testosterone Enanthate is a slow-acting injectable ester of testosterone. It was originally developed for hormone replacement therapy and remains one of the most commonly prescribed testosterone preparations in clinical medicine. In performance enhancement, Test E is valued for its predictable pharmacokinetics, long half-life, and versatility across bulking, cutting, recomposition, and strength cycles.

The enanthate ester extends the release of testosterone into the bloodstream, producing stable serum levels with once or twice weekly injections. This makes it more convenient than shorter-acting esters such as testosterone propionate, which requires injections every other day.

Common Uses and Cycle Guidelines

First Cycle (Beginner)

For users running their first cycle, Testosterone Enanthate is the recommended starting compound. A typical beginner protocol is 300mg per week (1ml) injected once weekly for 10 to 12 weeks, followed by a post-cycle therapy protocol beginning approximately 14 days after the last injection. This allows the enanthate ester to clear before PCT begins.

Intermediate Bulking

Intermediate users commonly run Test E at 400-500mg per week, often combined with a secondary compound such as Nandrolone Decanoate (Deca) at 300mg per week or an oral kickstart with Dianabol at 30mg per day for the first 4-5 weeks. An aromatase inhibitor such as Arimidex or Aromasin is typically included to manage estrogen-related side effects.

Cutting and Recomposition

During cutting phases, Test E is typically used at a lower dose of 150-250mg per week to preserve muscle mass while in a caloric deficit. It is frequently combined with compounds such as Masteron, Anavar, or Winstrol that do not aromatise or promote water retention.

TRT and Cruise

For testosterone replacement or cruise doses between blasts, 100-200mg per week maintains physiological testosterone levels. Bloodwork should be conducted every 8 to 12 weeks to monitor hormone levels, haematocrit, liver enzymes, and lipid profiles.

Storage and Handling

Store at room temperature (15-25 degrees Celsius) in a dry place away from direct sunlight. Do not refrigerate or freeze. Inspect the vial before each use. Do not use if the solution appears cloudy, discoloured, or contains visible particles. Use sterile injection technique and a new needle for each injection.

Post-Cycle Therapy

A PCT protocol is essential after completing a testosterone cycle to restore natural hormone production. Common PCT protocols include Clomid (Clomiphene Citrate) at 50mg per day and Tamoxifen (Nolvadex) at 20mg per day for 4 weeks, beginning approximately 14 days after the final Test E injection. Rohm Labs PCT products are available in our PCT and Anti-Estrogen category.

Lab Testing and Authenticity

This product is independently tested by a UK-based analytical laboratory using HPLC (High Performance Liquid Chromatography) to verify the identity and concentration of the active compound. Each vial includes a batch number that can be cross-referenced with our published results on the Lab Results page. Every Rohm Labs vial features holographic security labels and tamper-evident caps for authenticity verification.
