Stacks With:

PCT & Other:

Mass Stack 400 is, essentially, a classic Test Tren Masteron cycle in a vial.

It's the famed "Holy Trinity", all mixed carefully in an easy-to-pin and dose-adjusted blend.

It combines:

  • Testosterone Enanthate;
  • Trenbolone Enanthate;
  • And Masteron Enanthate.

Instead of using each steroid separately, run this blend to cover all the bases. Mass Stack 400 is a highly potent competitive AR antagonist without estrogenic, antiestrogenic, or progestogenic activity.

How Long is the Test Tren Mast Cycle?
Most of the time, the trinity, aka the Mass Stack 400, lasts 8 to 12 weeks. Most often, though, you'll see people dropping it and turning to a slow, calmer cruise after 6-8 weeks max. It's not about the sides: it's about the effects that you get in these time frames. 

Test Tren Mast Long Benefits
If you use the Tren Mast Cycle with proper guidance, you will get the following benefits:

  • Muscle Growth;
  • Strength Gains;
  • Enhanced Definition;
  • Increased Libido;
  • Improved Recovery.

Note: it's Mass Stack 400, not 500, with 400mg of each compound per ml, not 500, as it's usually used by experienced athletes. 

Tren Test Mast Long Half Life
All in all, with all the elements combined, the Test Mast Tren half life is around 7 to 10 days. This means that it takes 7–10 days for half of the Tren Test Mast in your system to be cleared. This half life is calculated for three steroid half lives; the partial half-life can be lower.

Tren Test Mast Long Dosage
The safe test-tren-mast cycle dosage is 300mg per week for beginners. Those with at least some experience with gear can up 300mg to 500mg per week. Advanced users can take 600mg per week. We recommend doing regular health checkups and consulting with a healthcare professional to avoid health risks at ALL doses anyway: this stack is not something you'd run as a first cycle. 

Tren Test Mast Long Cycle
The longest you can stay on a classic Test Tren Mast cycle is around 12-14 weeks. We recommend 8-10, though, and definitely recommend a decent PCT after the cycle. 

Side Effects of Test Tren Mast
If you don’t maintain safety guidelines for using the tren-mast-test blend, you may get the following side effects:

  • Cardiovascular Effects: Elevated blood pressure, changes in levels, and a growing risk of heart disease;
  • Hormonal Imbalances: Gynecomastia (development of breast tissue in men), Testicular Atrophy;
  • Organ stress: liver damage, kidney problems.

Also, remember that you can get psychological effects as well: mood swings, attacks, mental faith, acne and oily skin, hair loss, libido changes, and sexual vacuity.
