Primonon 100

Overview of UTINON Methenolone Enanthate

Methenolone enanthate, marketed under the UTINON brand, is an oil‑based injectable anabolic‑androgenic steroid belonging to the primobolan family. It is prized for delivering steady, moderate anabolic effects with a relatively low androgenic profile, making it a popular choice for athletes seeking lean muscle gains, enhanced recovery, and minimal water retention.

Pharmacological category

• Pharmacological Category: Anabolic‑androgenic steroid (primobolan)
• Anabolic Activity Index: ~130%
• Androgenic Activity Index: ~30%

Mechanism of action

Methenolone enanthate binds to androgen receptors in muscle and bone tissue, stimulating protein synthesis and nitrogen retention. Its long‑acting ester (enanthate) provides a slow release of the active compound, resulting in stable plasma concentrations that support gradual muscle accretion and strength improvements without significant estrogenic conversion.

Side effects

Although considered milder than many AAS, potential adverse effects include:

• Suppression of natural testosterone production
• Acne and oily skin
• Hair loss in genetically predisposed individuals
• Elevated cholesterol (decreased HDL, increased LDL)
• Potential liver strain (though lower than oral steroids)
• Possible mood swings or irritability

Dosage recommendations

• Standard dose: 100 mg per week (administered intramuscularly)

Users should monitor hormonal panels and liver function regularly and consider post‑cycle therapy to restore endogenous testosterone production.
