Firstly anabolic steroids are a class of natural and synthetic steroid hormones that promote cell growth and division, resulting in growth of muscle tissue and sometimes bone size and strength. Anabolic steroids are the synthetic derivates of male anabolic hormone testerone. Some anabolic steroids are Deca Durabolin, Sustanon, Winstrol Depot, Winstrol, Andriol, Anavar and other.

The base substance of Deca Durabolin is Nandrolone Decanoate. Nandrolone Decanoate is a male sex hormone given to treat a lack of testosterone, bone breakdown, female breast cancer, stimulation of growth, weight gain, and the making of red cells. Nandrolone Decanoate works as it is easy on the liver and promotes good size and strength gains while reducing body fat. This drug is unique in that 5a -reductase, the enzyme which converts testosterone to the more-potent DHT, actually converts Nandrolone to a less-potent compound. Therefore, this is somewhat deactivated in the skin, scalp, and prostate, and these tissues experience an effectively-lower androgen level than the rest of the body.

But there are some also some drawbacks or side effects Nandrolone Decanoate (Deca Durabolin) also has some side effects which are Water retention (edema), Gynecomastia, Numbness, Inhibited natural testosterone production, Elevated blood pressure , Elevated blood lipid profiles, Accelerated hair loss , Aggression, moodiness and Acne. I must remind you that Deca Durabolin has long half-life so it isn't very suitable for short alternating cycles, but it is better for more traditional cycles, with a built-in self-tapering effect in the weeks following the last injection. Yes Deca Durabolin is taken with administration by deep intermuscular Injection.

Sustanon 250 is an oil-based injectable containing four different testosterone compounds: testosterone propionate, 30 mg; testosterone phenylpropionate, 60 mg; testosterone isocaproate, 60mg; and testosterone decanoate, 100 mg. It features both fast-acting and slow-acting esters, and can be injected anywhere from once every week to once every four weeks. Sustanon is used to be taken with Nolvadex or Proviron to counter and prevent estrogen-linked side effects. Testosterone Propionate: Chemical Formula C3H6O2, Testosterone propionate is a fast-acting ester with a release time of 3-4 days. To keep blood levels from fluctuating greatly, propionate is usually injected between one to three times a week. Testosterone Phenylpropionate: Chemical Formula C9H10O2, Testosterone phenylpropionate is a slow-acting ester, with a release time of 1-3 weeks. A popular name brand for T-phenylpropionate is "Testolent." Testosterone Isocaproate: Chemical formula C6H12O2, Testosterone Isocaproate is a ester with a release time of 1 week.Testosterone Decanoate: Chemical Formula C10H20O2, Testosterone Decanoate is a ester with a release time for about a month, but recent discoveries show that levels drop siginficantly drop in a few weeks.

Andriol is a brand name for Testosterone Undecanoate Testosterone undecanoate is not a c-17 alpha alkylated hormone. Therefore, it is considered a safer oral form of testosterone. Additionally, it is absorbed through the small intestine into the lymphatic system, posing less burden on the liver. Undecanoate: Chemical Structure C11H22O2. Undecanoate is not a commonly found ester, and appears in oral testosterone undecanoate (Andriol). It is an ester with a release time of 2-3 weeks.
