When efficiency, lean mass, and fat-loss synergy matter most, Ultradex 150 stands out as one of the most strategically designed blends on the market. Previously known as Cut Mix 150, this fast-acting injectable from Sciroxx brings together three anabolic heavy-hitters—Testosterone Propionate, Trenbolone Acetate, and Masteron Propionate—into one formidable formula for serious athletes.
Ultradex 150 is a potent tri-blend injectable steroid that delivers 150mg per ml in a finely balanced ratio:
Available in 10ml vials, this combination is favored by advanced users for its fast results, dry muscle gains, and minimal water retention. Ultradex is especially popular in cutting and recomposition phases, helping athletes sculpt a harder, leaner, and more vascular physique.
The power of Ultradex lies not just in its ingredients—but in how they work together. Each compound enhances the others through multiple anabolic mechanisms, resulting in amplified outcomes from a relatively moderate dose.
This fast-acting ester of testosterone kicks in quickly to stimulate muscle growth. As the body’s primary androgen, testosterone serves as the foundation of any effective muscle-building cycle—driving protein synthesis, optimizing the anabolic environment, and enhancing training aggression. Its short ester chain leads to reduced estrogenic side effects due to rapid clearance from the system.
Renowned for its powerful effects on lean muscle development and fat reduction, Trenbolone is unmatched in nutrient partitioning and anti-catabolic activity. It amplifies anabolism while preventing muscle breakdown—making it one of the most effective and efficient steroids ever created.
As a DHT-derived compound, Masteron helps create a dry, sculpted appearance while offering mild anti-estrogenic support. By binding strongly to SHBG, it increases the availability of free active steroids—enhancing the overall impact of the blend.
This scientifically engineered blend creates a synergy where 1 + 1 + 1 equals more than 3—each compound enhances and amplifies the others, producing a unified anabolic symphony unlike any single-agent steroid cycle.
Expect visible results within the first week, thanks to the fast-acting esters. This blend promotes dramatic improvements in performance, strength, and lean mass with minimal water retention.
Yes—you can, and you will—burn stubborn fat while gaining lean tissue with Ultradex. That’s the hallmark of an elite recomp phase, and this blend was designed to maximize it.
Ultradex 150 Key Benefits
The Mast-Tren synergy delivers a hard, vascular, competition-ready look—free from bloat or puffiness.
Ideal for calorie-restricted cutting cycles, Ultradex protects muscle tissue while accelerating fat loss and preserving training intensity.
Thanks to inter-compound synergy, users report significant results even at moderate dosages—making Ultradex both powerful and efficient.
Given the short esters, frequent injections are needed to maintain stable blood levels.
Inject deeply into muscle tissue. Cycles typically range from 6 to 8 weeks, depending on individual goals and tolerance.
Ultradex can function independently or be paired with oral steroids for enhanced results.
This hybrid approach enables you to tailor the stack to your aesthetic or performance goals.
Ultradex is a go-to for physique athletes looking to lean out. It offers:
It’s a popular option leading into summer or contest prep.
As with any powerful anabolic blend, there are possible downsides:
