Methenolone Enanthate (Primonon) 100 mg

Primonon (Methenolone Enanthate) 100 mg is Utinon's long-ester Primobolan injectable, supplied as a 10 ml vial at 100 mg/ml. Methenolone is a DHT-derived androgen with a mild reputation, and the enanthate ester releases over roughly one to two weeks. Each vial is sealed in a printed carton with a scratch-off authenticity code.

What Primonon 100MG Is

Methenolone is a dihydrotestosterone derivative with a methyl group at carbon one and no methyl at carbon 19. It does not aromatise and has low androgenic activity relative to its anabolic effect. The enanthate ester is long and lipophilic, so release from the depot is slow. A 10 ml vial at 100 mg/ml contains 1,000 mg of methenolone enanthate.

The History of Primobolan

Methenolone was developed in the 1950s and marketed as Primobolan, first as an oral acetate and later as an injectable enanthate. It was used clinically for anaemia and wasting, and it acquired a reputation as one of the mildest anabolics available. That reputation, combined with high manufacturing cost, made it one of the most counterfeited compounds in the category.

How It Works

Esterases hydrolyse the enanthate ester slowly, releasing free methenolone over one to two weeks. Methenolone binds the androgen receptor and supports protein synthesis without aromatising, so oestrogenic water retention is minimal. It is metabolised in the liver and excreted mainly in urine. The long ester keeps levels steady, but it also means the compound clears slowly after the last injection.

What the Research Shows

• Methenolone has been studied for anaemia and muscle-wasting conditions.
• Its non-aromatising profile and low androgenic rating are well documented.
• Enanthate esters produce prolonged release compared with the oral acetate.
• Analytical detection methods are well established because of its long history.

Research Context

Primobolan is the mild reference point in the DHT-derived group. Its clinical work focused on lean tissue preservation, and its modern research role is as a comparator for other non-aromatising androgens. The high cost of synthesis is why counterfeit packs are common, and it is why the authenticity code matters more here than on most lines. The enanthate is the slow end of the methenolone pair.

Strength, Pack and Authentication

Each millilitre contains 100 mg/ml of methenolone enanthate, giving 1,000 mg / 10 ml in the 10 ml vial. The vial is sealed with a flip-off cap and boxed in a printed carton that states the compound, strength and volume. A scratch-off security code inside the box links the pack to Utinon's manufacturing records.
