Magnum Pharmaceuticals’ Test-C 300 is an injectable steroid containing Testosterone in one of its longer-estered forms, Testosterone Cypionate. This ester is one of the most commonly used in the medical field in the USA but is also one of the most popular steroids for bodybuilding worldwide. Similar to testosterone enanthate, it is one of the most used steroids in bulking cycles.

Testosterone Cypionate effects

The steroid has powerful anabolic and androgenic effects, that are extremely beneficial when a user wants to:

  • Build high-quality muscle mass
  • Increase their appetite
  • Gain more strength
  • Extend their endurance
  • Increase their sex drive during a cycle
  • Receive increased motivation for training
  • Improve their recovery time after intense workouts

How to take Test Cypionate

The injectable testosterone has an extended period of action so injections are only necessary every 7 days, although many steroid users may split the weekly dose into two injections to maintain peak hormone levels. The maximum recommended testosterone cypionate dosages start at 250mg weekly for beginners and end at 1000mg weekly for experienced steroid users. A test cypionate cycle will typically need to be at least 6 weeks long and can last for up to 14 weeks if necessary.

Testosterone cypionate is generally used as a base steroid in cycles containing other anabolic steroids. For mass-building cycles, it is commonly stacked with bulking steroids such as Nandrolone Decanoate (Deca Durabolin) or Boldenone Undecylenate (Equipoise.)

A Testosterone Cypionate cycle results in a fair amount of water accumulation, which is removed from the body after the cycle. To reduce water retention caused by testosterone cypionate, steroids such as Stanozolol (Winstrol) or Drostanolone Enanthate (Masteron) can be added to the cycle.

    I like TestC as my go-to test in my stack. I prefer doing it in shorter cycles of 8 weeks at the most because the longer you’re on the stuff the longer the recovery is. This way I can get more cycles in throughout the year. So in this case less is actually more. Very good for getting the best returns out of your workouts.

    As someone who is very sensitive to the fluctuations of hormones I get when I’m on a cycle I’ve found that the cypionate is the best of the bunch in terms of keeping me running smoothly. When I was running prop or sust it was a nightmare on my moods which was killing my social life. I’ve found I’m actually generally in a positive mood all the time when I’m running these cycles now, and I still get all of the gains. Seems like a win-win to me.
