What is Big N Full (EQ 200 / Test 400)?
Big N Full is a pre-loaded combo stack containing Boldenone Undecylenate (EQ 200mg) and Testosterone blend (Test 400mg) across 5 vials. It was originally developed as a convenient all-in-one bulking solution for serious athletes. The combination is popular for putting on lean mass while keeping water retention manageable.

How Does It Work?
Boldenone binds to androgen receptors and boosts nitrogen retention, which helps the body build and hold onto muscle tissue. The testosterone component keeps natural hormone levels stable and adds its own powerful anabolic effect. Together they create a strong environment for muscle growth, increased red blood cell production, and better recovery.
What It's Used For
- Building lean muscle mass during a bulk
- Increasing strength and endurance over longer cycles
- Improving red blood cell count for better oxygen delivery to muscles
What to Expect
Results come in gradually — most users start noticing fuller muscles and improved endurance within 4–6 weeks. By the end of a full cycle, expect solid lean mass gains with less bloating than typical testosterone-only bulks. Appetite tends to increase noticeably, which can help with higher calorie intake during a mass phase.
Possible Side Effects
- Increased oil production and acne, especially on the back and shoulders
- Natural testosterone suppression requiring post-cycle therapy (PCT)
- Elevated red blood cell count (increased blood viscosity if unchecked)
- Mild androgenic effects such as hair thinning in those predisposed
- Potential for elevated estrogen-related effects from the testosterone component
Cycle & Dosage Notes
This stack works best in longer cycles of 12–16 weeks due to the slow-acting nature of Boldenone Undecylenate. A standard PCT using Nolvadex or Clomid should begin approximately 2–3 weeks after the last injection. It stacks well with an oral kickstart such as Dianabol in the early weeks if faster initial gains are desired.
Storage
