(nandrolone/methandriol blend)
Tribolin, also known as Tribolin 75, is a specially formulated veterinary steroid blend, combining nandrolone and methandriol in a mild formula. This compound is made up of 40 mg/ml of methandriol dipropionate and 35 mg/ml of nandrolone decanoate, culminating in a total steroid concentration of 75 mg/ml. It is typically available in multi-dose vials of 10 and 20 mg/ml. Another variant, Filybol Forte, produced by the same manufacturer, Ranvet Company, offers a slightly different composition with a total concentration of 70 mg/ml, adjusting the nandrolone content.

- Manufactured by: RWR.
- Dosage: Recommended dosages for men range from 200-400mg per week, equivalent to about 2mg per lb of body weight, whereas for women, it is suggested between 50-100mg per week.
- Active Life: Approximately 15 days.
- Detection Time: Tribolin can be detected up to 18 months after usage.
- Anabolic/Androgenic Ratio: 125/37, indicating a favorable balance towards anabolic effects.
Steroid Formulation:
Tribolin is designed for intramuscular injection, providing a direct method of administration for its anabolic effects. The oil-based preparation ensures a sustained release of the active ingredients, making it a preferred choice for consistent muscle growth and performance enhancement.
Usage and Efficacy:
While primarily used in veterinary applications, Tribolin’s unique blend has found a place in bodybuilding circles, especially when aiming for muscle hardening, water retention reduction, and improved vascularity. Its effectiveness is not just limited to standalone use but extends to being a valuable component in both bulking and cutting cycles. For bulking, it is often combined with testosterone and powerful oral steroids like Oxymetholone (Anadrol) or Methandrostenolone (Dianabol). In cutting phases, it synergizes well with short-ester injectables such as testosterone propionate, Boldenone Acetate, and DHT-derived orals like Stanozolol (Winstrol) and Oxandrolone (Anavar).
Methylandrostenediol, despite its mild anabolic and androgenic properties, enhances the overall efficacy of the blend. Derived from dihydrotestosterone (DHT), it contributes significantly to the anabolic cocktail, especially when paired with more potent compounds. This strategic combination amplifies the desired anabolic effects, making Tribolin a versatile option for athletes looking to optimize their performance and physical development.
In summary, Tribolin represents a sophisticated blend of anabolic steroids, meticulously designed to support muscle growth, enhance physical performance, and improve aesthetic appearance through muscle hardening and vascularity. Its careful formulation and versatile application make it a valuable tool in the arsenal of performance enhancement strategies, catering to both bulking and cutting cycles.
