What is Test 400
Test 400 is a blend of three popular testosterone esters: Testosterone Cypionate, Testosterone Propionate, and Testosterone Enanthate. Since all of these esters have different half-lives, they will increase your testosterone levels without any peaks or dips in the compound's serum concentration.
Test 400 is a versatile steroid that can be used in bulking, cutting, or recomposition cycles.
Test 400 Benefits
Test 400 can help you to:
- Increase muscle mass: Test 400 can stimulate protein synthesis, increase metabolic rate, and promote nitrogen retention. Overall, you can gain around 15–25 lbs, depending on your diet, training program, and individual response to Test 400;
- Increase strength: you can’t see strength gains immediately, but you’ll increase your working weight or reps’ quantity closer to 4 or 5 week of the cycle;
- Speed up recovery: Test 400 allows you to recover faster, boosts your energy levels, and improves muscle oxygenation;
- Improve libido: all testosterone esters can enhance one’s sex drive and sexual function.
During cutting cycles, Test 400 will act as an anabolic base, useful in retaining lean muscle mass. Some users have reported slight muscle gains, however, it’s not always possible on a low-calorie diet.
