C-Ject 250 is a pharmaceutical-grade, single-ester injectable testosterone formulation manufactured by Thaiger Pharma. Packaged as a box of 10 individual 1ml single-use glass ampoules, each ampoule delivers 250mg/ml of Testosterone Cypionate. Testosterone Cypionate is one of the most widely prescribed and utilized long-acting testosterone esters in male hormone replacement therapy (TRT) and anabolic performance protocols.

Featuring the eight-carbon cypionate ester, C-Ject 250 offers smooth, extended release kinetics into the bloodstream, maintaining stable target serum testosterone concentrations over 7 to 10 days. Single-dose glass ampoules ensure maximum product purity, zero risk of rubber stopper degradation, and precise unit dosing for muscle hypertrophy, strength enhancement, and hormonal balance.

Key Benefits & Applications

Consistent, Sustained Hormone Levels: The long Cypionate ester produces steady serum testosterone levels, allowing for simple once- or twice-weekly dosing regimens without drastic hormone spikes or crashes.
Significant Muscle Hypertrophy & Strength: Drives rapid increases in muscle protein synthesis, satellite cell recruitment, and total nitrogen retention, resulting in substantial gains in muscle size and workload capacity.
Enhanced Glycogen Storage & Muscle Fullness: Increases cellular glycogen resynthesis and intramuscular water volume, producing dense, full muscle bellies and accelerated recovery between training sessions.
Improved Erythropoiesis & Oxygen Transport: Stimulates renal erythropoietin (EPO) release, increasing red blood cell volume and oxygen delivery to working skeletal muscle tissue.
Glass Ampoule Sterility & Dose Precision: Single-use sealed glass ampoules protect the active compound from oxidation and ensure exact 250 mg dosing per application.
