We’ve all read about the steroid horror stories in newspapers and magazines. And have seen the hatchet jobs that filmmakers sometimes create regarding the use of anabolic steroids. So what can we believe? Well, that’s the million-dollar question, really, isn’t it?

We know that steroids can be dangerous, but we also know that they provide a number of benefits as well.

In today’s article, we are going to look at a testosterone cypionate cycle guide. As we look at what testosterone cypionate is, what it does, how much to take, side effects, and much more besides.

As you probably know, when you bust your ass in the gym, training like a man possessed, choking down egg white omelet after egg white omelet, followed by chicken breast after chicken breast. Only to see your physique barely changing at all, it can be incredibly disheartening. Many people go through this, and we often ask ourselves what the point is in carrying on.

After all, we’re training until we’re close to puking. We’re sacrificing nice and greasy food in exchange for bland, protein-rich food that fills us up and gives us gas, and for what? Our muscles aren’t growing, we’re barely losing fat, and our physique is not getting any better.

In circumstances like these. You can understand the appeal of androgenic anabolic steroids such as the testosterone cypionate we are going to be looking at today. If you are tempted to turn to the dark side, here’s a better look at Test-C.

What Is A Testosterone Cypionate Cycle?

Testosterone cypionate is very popular in the world of bodybuilding and health and fitness in general. Testosterone cypionate is actually available on prescription and is used by men to treat low testosterone levels. Now, testosterone is a hormone that men and women produce naturally.

Though in men the amounts produced are much higher than those in women. The hormone is a primary sex hormone in men and is produced in the testes. With very small doses being produced and secreted via the adrenal glands. Test cypionate is a lab-made synthetic version of testosterone. It is essential for muscle function, size, and strength, making it a firm favorite amongst bodybuilders and strength athletes.

You see, out of all of the steroids currently available, I.E Tren, Winstrol, Deca, etc, all steroids are derived from testosterone as they are basically testosterone molecules which have been altered. Testosterone cypionate, and indeed other forms of testosterone, carry an androgenic/anabolic rating of 100. This is the highest rating going, so that should show you just how beneficial this steroid can be. A cycle, therefore, is a steroid cycle placing an emphasis on this very hormone. Sometimes it is run individually, whereas other times it can be stacked with other steroids.

Testosterone Cypionate Benefits:

Testosterone Cypionate Cycle

In terms of performance enhancement and looking better in general. Test-C provides a wide range of benefits to its users, making it one of the best steroids currently available. A few key benefits and effects of testosterone cypionate include:

Muscle Growth

First and foremost, as test C is such an androgenic and anabolic hormone, it is perfect for people looking to build muscle and bulk up their physiques. Those that run Test-C can potentially add as much as 30 pounds of muscle with just one cycle. Providing their diets and lifestyles are in order and that they know what they’re doing in the first place.

One of the main ways in which testosterone cypionate is able to promote muscle growth is because it encourages the muscles to retain more nitrogen. Nitrogen is essential for protein synthesis to occur. Which is where the body synthesizes new muscle proteins to help repair and rebuild muscle tissue. The greater the rates of protein synthesis, the greater the amounts of muscle growth will be.

Improved Rates Of Repair And Recovery

As if speeding up protein synthesis wasn’t enough, another key benefit of Test-C is the fact that it enhances satellite cell activity in the muscles. These cells are vital, due to the fact that they work by assisting with the repair of damaged muscle tissues.

Test- C, therefore, helps to protect the muscles from the damaging effects of muscle catabolism, so you can prolong your training sessions before you begin to fatigue and weaken.

Increased Strength Levels

Another reason to consider running a cycle is due to the fact that doing so will also help increase your strength levels. Testosterone plays a vital role in the functioning of healthy muscle tissue, and one way in which it helps is that it improves muscle contractions.

The harder the muscles can contract, the more power you can generate, and the stronger you become. Being strong isn’t just so that you can brag to your buddies about how much you deadlift, being strong also enables you to train harder and more intensely. And subsequently, you’ll find that your workouts become more productive as a result.

Increased Sex Drive

Finally, this last benefit will not help you in the gym, or at least, we hope it won’t, but it will help you in the bedroom. Or wherever else you choose to engage in an amorous extracurricular activity in your free time. As testosterone is the primary male sex hormone. It’s safe to say that the hormone plays an important role in determining just how amorous you are feeling.

As a male, either single or in a committed relationship, having a low libido sucks. We know how awesome sex is, and we know that it’s even better when you are properly in the mood for it. Running a cycle will increase your libido dramatically. Enabling you to enjoy a better sex life, whenever you’re fortunate enough to get lucky.

Testosterone Cypionate Side Effects:

As you know, one of the main reasons why are steroids bad, and have such a bad reputation is all due to the fact that they provide some pretty severe side effects. While side effects vary from person to person. If you run a cycle, even with PCT (which you should always use anyways) you are likely to encounter some pretty nasty side effects. Typical examples include:


One of the biggest downsides to Test C is the fact that it does aromatize. This means that the testosterone can be converted into Estrogen within the body. Estrogen for a bodybuilder is what Kryptonite is to Superman. Estrogen suppresses the metabolism and promotes fat gain, it can cause water retention, bloating, gyno, and much more besides.


We mentioned gyno above, but we need to go into more detail to emphasize just how detrimental gyno can be. Gynecomastia may not be life-threatening, but it can leave people feeling miserable and very self-conscious. Sometimes people refer to gyno as ‘bitch tits’ which is because of the fact that it causes men to basically grow breast tissue, or rather, to store fatty deposits on their pecs, normally around the nipple area. Mild gyno can cause the nipples to look swollen and puffy. Whereas extreme gyno can literally result in men looking as if they have real breasts. PCT helps to reduce the chances of this occurring.


Test C is an injectable steroid, and so as it has to be injected, there are always risks to be wary of. While you should always use clean, sterile, new needles and inject clean and sterile injection sites. Occasionally things can go wrong and you can find yourself suffering from an infected injection site. If you’re lucky, the infection can be cleared up with antibiotics, but sometimes necrosis of the skin can occur. Sometimes you will simply experience a sore, slightly swollen injection site, but it is still something you would like to avoid in an ideal world.

Prolonged Erections

Okay, get your minds out of the gutters and stop giggling as we’re all supposed to be adults here, aren’t we? We mentioned how testosterone helps to boost libido, and you obviously know what happens when a guy is turned on. In most cases, an erection may last a few minutes (unless you’re engaging in sexual activity) but with test C, sometimes an erection can last four several hours at a time. It can be worrying and can result in a headache as the blood is obviously being diverted somewhere else if you catch our drift. Normally the erection will eventually go away. Although if you are worried you can speak to an expert who may be able to put your mind at ease and prescribe medication if they deem it appropriate.

Testosterone Cypionate Dosage:

If you were paying attention before, you will have noticed how we gave you three sample testosterone cycles for you to go consider running. Which listed the dosages of Test C, along with dosages of the other steroids used in conjunction with the test. Just to ensure that there is no confusion, however, we’ll give you a quick recap of the dosages of Test C, just to make sure that we’re all on the same page here. As far as dosages go, typically you should aim for 500mg – 600mg per week. People normally split this into two injections, so perhaps Mon and Thurs. Dosages are then halved, so 300mg x2 per week, or 250mg x2 per week. Beginners, however, typically aim for 250mg per week, split into two dosages, so 2 x 175mg spaced out at least three days as a first steroid cycle.

Post Cycle Therapy:

Before we wrap things up, we need to talk to you about PCT. After running a testosterone cypionate cycle, or any steroid cycle for that matter. Even the Clenbuterol, one of the most important things you need to remember, is your post cycle therapy. PCT isn’t just something that you do if you can be bothered, PCT is something that you should always do after finishing a steroid cycle, no matter what. PCT is designed to help restore your body back to how it was before you ran the cycle. PCT should come in the form of Nolvadex and Aromasin, which is the same for countless other steroid cycles too, and should look something like: 2 weeks after the final injection:

  • Nolvadex at 40/40/20/20
  • Clomid at 60/60/60/60

This was a very informative article. Thank you. I want to try a 10 week cycle of Test C without my doctor. Any ideas on where to get it?

I’m confused about two parts. On the PCT, is that daily dosage of clomid and nolvadex? and at the end talks about PCT it shows 40/40/20/20. What does this mean exactly?
