Information about Promass 300

PROMASS 300 is a blend of three potent anabolic steroids that are used by bodybuilders and athletes worldwide to enhance performance, gain lean muscle mass and increase their strength. These anabolic androgenic steroid were picked from a group of strong steroids to serve as one powerful drug able to grant lean muscle mass in one injection.

PROMASS 300 contains 100mgs of Trenbolone enanthate, 100mgs of Drostanolone enanthate and 100mgs of Testosterone enanthate. This combination is perfect for those who look for muscle gains and an enhancement in their performance in off season cycles and even in cutting cycles. These anabolic steroid will increase protein synthesis, which is considered to be the base brick for muscles to grow. They also increase nitrogen retention and inhibit glucocorticoid hormones. The more nitrogen returning into muscles tissue the more anabolic they get, and glucocorticoids can force they body to be in a catabolic state and accumulate fat; thus by inhibiting them and increasing nitrogen a better anabolic atmosphere is provided for muscles to become stronger and grow bigger.

Drostanolone and Trenbolone don’t aromatize, and drostanolone, also known as Masteron, serves as ant estrogenic agent. Meaning that these strong anabolic steroids won’t cause unwanted estrogenic side effects such as water retention or gynecomastia. As for testosterone, it is a well tolerated steroid for most healthy adults with controllable side effects.

The Enanthate ester that is attached to every single steroid in this blend will increase half-life and prolong their releasing time, thus prolonging the physiological response to every steroid in this anabolic blend.
