Mass 400

Mass 400 is a highly potent injectable blend formulated for maximum muscle mass, combining three powerful testosterone esters: Testosterone Enanthate, Testosterone Cypionate, and Testosterone Propionate — with a total concentration of 400mg/ml in a 10ml vial], it’s one of the most cost-effective heavy hitters for advanced bulking cycles.

Each ester plays a unique role:

• Testosterone Propionate kicks in fast for early anabolic effects

• Enanthate and Cypionate provide sustained release and stable blood levels

This unique synergy supports rapid strength gains, muscle fullness, and enhanced nitrogen retention, while reducing the frequency of injections compared to single-ester products.

Mass 400 is best suited for experienced users undergoing intense bulking cycles or offseason strength building. It’s often stacked with Deca, EQ, or orals like Dianabol for even more dramatic results.

Now available at An Apple Pharmacy UK for only £44.99, with discreet shipping and trusted quality.

Frequently Asked Questions (FAQs)

1. How often should I inject Mass 400?
Due to its mix of short and long esters, most users inject 2–3 times per week to maintain consistent testosterone levels.

2. What’s the ideal cycle length for Mass 400?
A typical cycle runs between 10 and 14 weeks. This allows the longer esters to stabilize while benefiting from the early kick of propionate.

3. Is post-cycle therapy (PCT) necessary after Mass 400?
Yes. As a high-dose testosterone blend, it will suppress natural production. A proper PCT protocol with SERMs like Clomid or Nolvadex is essential to restore hormonal balance.
