Test U 300mg/ml

**Testosterone Undecanoate 300mg/ml – Ultra Long-Acting Testosterone**

**Overview:**
Testosterone Undecanoate is the longest-acting ester of testosterone available, used primarily in long-term hormone therapy (TRT) or extended anabolic support protocols. At 300mg/ml, this formulation is ideal for users seeking less frequent injections with stable testosterone output.

**Action Profile:**
Has a half-life exceeding 20 days. Reaches peak concentration slowly but provides extended coverage with minimal hormonal fluctuation.

**Key Advantages:**
– Injections only every 2–4 weeks
– Ideal for TRT users or slow-release base in stacks
– Extremely steady state hormone levels

**Typical Protocol:**
– Standard dose: 600–1000mg every 14–21 days
– Advanced users: front-load with faster ester like Test P
– Injection: deep IM (glute preferred)

**Best Combinations:**
– Test U + EQ or Primo for long-cycle lean mass
– Add short esters for hybrid control
– Avoid if rapid adjustment needed

**Side Effects:**
– Slow to leave system if side effects occur
– Possible elevation in RBC and hematocrit
– Monitor E2, lipids, and prolactin

**Storage & Handling:**
Due to viscosity, warm prior to injection. Store upright in a cool, dry environment.

**Pro Tip:**
Best used for long cruises or once-monthly therapeutic injections.
