Shredder (Test P + Mast P + Tren A – 150 mg Total): High-Impact Cutting & Recomp Blend

Shredder is a fast-acting anabolic blend formulated for aggressive cutting, lean muscle retention, and extreme physique hardening. It combines Testosterone Propionate, Masteron Propionate, and Trenbolone Acetate into a single high-potency 150 mg mixture designed to deliver powerful results with minimal water retention. Popular among experienced lifters during shredding phases, this blend maximizes fat loss, muscle density, and strength within a short cycle window.

Shredder is best suited for users who want a compact, high-impact combination that enhances performance, preserves muscle during caloric deficit, and produces dry, sharp physique changes.

How Shredder Works

Testosterone Propionate

Acts as the androgenic base supporting muscle growth, strength, libido, and recovery. Propionate’s fast-acting ester ensures stable blood levels with less water retention compared to longer esters.

Masteron Propionate

A DHT-derived compound that enhances muscle hardness, vascularity, and dryness while helping regulate estrogen naturally. Its cosmetic effects amplify the “shredded” look, especially at lower body fat.

Trenbolone Acetate

A potent anabolic known for extreme nutrient partitioning, fat burning, and muscle preservation. Tren increases protein synthesis, boosts strength, and keeps the body anabolic even during aggressive dieting.

Together, these three compounds create a synergistic effect: testosterone drives anabolic processes, masteron sharpens the physique, and tren multiplies fat loss and muscle retention.

How to Use 

Dosage

Because Shredder totals 150 mg per injection, typical dosing for beginners to intermediates is:

• 75–150 mg per injection

• Total weekly: 225–450 mg

Low doses are recommended for new users due to the presence of trenbolone.

Frequency

• Every day (ED) or Every other day (EOD)
  Fast esters require frequent injections to maintain stable hormone levels and reduce side effects.

Cycle Length

• 6–8 weeks
  This blend hits fast and hard, but trenbolone duration should be limited for safety and tolerability.

Stacking

Often used alone for cutting, but can be paired with:

• GH peptides (CJC-1295, Ipamorelin, Tesamorelin)

• Fat-loss peptides

• Orals like Anavar or Winstrol for competition-level hardness

Not recommended to combine with other harsh DHTs or additional tren.

Proper support, frequent injections, hydration, and regular bloodwork are strongly recommended.
