Opal Pharma MASS 400 – Serious Strength and Muscle Gains in One Powerful Blend

Opal Pharma MASS 400 is a high-strength injectable anabolic blend crafted for experienced bodybuilders and athletes who are focused on building serious size and power. Each 1ml dose delivers a total of 400mg of active ingredients, combining three well-known long-acting esters:

• 200mg Testosterone Enanthate

• 100mg Trenbolone Enanthate

• 100mg Drostanolone Enanthate (Masteron)

This potent combination brings together the muscle-building power of testosterone, the cutting and hardening effects of Masteron, and the advanced performance support of Trenbolone. MASS 400 is ideal for bulking cycles or body recomposition phases, helping you build lean mass, increase vascularity, and improve definition when paired with a disciplined diet and training program.

Thanks to its long esters, MASS 400 provides a slow and steady release, typically becoming noticeable within two to three weeks. Most users find success with a dosage of 400 to 800mg per week, divided across one or two injections. Advanced users may increase the dose cautiously, but given the high potency—especially from the Trenbolone component—it’s best to begin at a moderate level and adjust based on results and tolerance.

Opal Pharma is known across the UK for manufacturing reliable, pharmaceutical-grade compounds. MASS 400 saves you the hassle of combining multiple vials or planning complex cycles by delivering everything you need in a single, powerful formula.
