CAS 315-37-7 Anabolic Bulking Cycle Steroids Primoteston Testosterone Enanthate



Testosterone Enanthate Description


  1. Testosterone is the king of all mass builders and for this purpose is also fairly cost effective.It works well either alone or stacked to create a great bulking cycle.It has a high risk of side effects due to its conversion to DHT and has the potential to form estrogen,causinggynecomastia.These characteristics also cause it to have such excellent mass building tendencies.Due to some other side effects,such as water retention,it may not be the best used alone for lean mass gains,but with bulking comes the addition of a lot of muscle as well as some gains in fat and water weight.This is typical and a natural part of the enhanced bodybuilder's bulking regiment.
  2. Testosterone enanthate is a long lasting single ester steroid.It is 7 carbons in length.What this means,is that more of the weight of the steroid is testosterone as opposed to ester weight.When taking a quantity of an esterified steroid,the total weight is a combination of both the ester weight and the steroid.That said,longer esters such ascypionatehave more ester weight(due to it's 8 carbon length),and less overall steroid weight.For this reason,enanthate would be preferred over cypionate.Sustanonhas even more steroid weight.
  3. 500 mg of enanthate has more free based testosterone than 500 mg of cypionate and 500 mg of sustanon has more than either.However,due to the irregular release of sustanon and the need to inject more frequently to take full advantage of thepropionateand phenylpropionate esters and thereby make full release of the steroid itself,either enanthate or cypionate will be better choices for the first time user,who will likely want to maintain stable blood levels of the steroid while minimizing injection frequency.
  4. A long acting testosterone ester will be very helpful for your bulking needs,and enanthate is a product which is more simple than some of the other steroids out there.Not to say it is without its share of complications,but it's a good choice,especially for those new to enhanced bodybuilding.Discontinuing the product is not an option in case side effects occur,because it will continue to aggravate these side effects over extended periods of time due to the long length of action of this steroid(3-4 weeks).Ancillary drugs such asnolvadex,proviron,clomidandHCGmay help,both during cycle and post cycle to help restore natural testosterone production.Testosterone enanthate does aromatize slightly more than sustanon,but when using either drug,one should be familiar with anti-estrogens such as nolvadex or clomid and use one of them when symptoms of gyno occur.
  5. Those who have prostate problems or those who are sensitive to gyno(for example,those who developed a case of gyno during puberty),and those who are sensitive to female pattern fat deposits will want to ensure anti-estrogens are on hand during cycle in case gyno related side effects arise.As a general rule of thumb,you will always want to keep nolvadex on hand-but obviously,it is even more important if the risks of these side effects are higher than normal(depending on the user and his or her genetic predisposition).
  6. Like any other testosterone,enanthate suppressed HPTA function.Clomid or nolvadex are important to have post cycle to stimulate normal testosterone function within a reasonable amount of time.You may also want to use HCG during your cycle,but this is matter of personal preference,as many feel they will be able to recover post cycle and don't feel the benefit of HCG is worth the cost.Normalization of natural functions which were suppressed during cycle and testosterone production usually occur without the use of HCG,but at a slower rate than if it was used.Like anything in life,there is no guarantee of full recovery,but it would be a rare case if it did not happen.


Indications and Usage for Testosterone Enanthate



  • Testosterone Enanthate Injection, USP is indicated for replacement therapy in conditions associated with a deficiency or absence of endogenous testosterone.
  • Primary hypogonadism (congenital or acquired) – Testicular failure due to cryptorchidism, bilateral torsion, orchitis, vanishing testis syndrome, or orchidectomy.
  • Hypogonadotropic hypogonadism (congenital or acquired) – Gonadotropin or luteinizing hormonereleasing hormone (LHRH) deficiency, or pituitary-hypothalamic injury from tumors, trauma, or radiation. (Appropriate adrenal cortical and thyroid hormone replacement therapy are still necessary, however, and are actually of primary importance.)
  • If the above conditions occur prior to puberty, androgen replacement therapy will be needed during the adolescent years for development of secondary sexual characteristics. Prolonged androgen treatment will be required to maintain sexual characteristics in these and other males who develop testosterone deficiency after puberty.
  • Safety and efficacy of Testosterone Enanthate Injection, USP in men with “age-related hypogonadism” (also referred to as “late-onset hypogonadism”) have not been established.
  • Delayed puberty – Testosterone Enanthate Injection, USP may be used to stimulate puberty in carefully selected males with clearly delayed puberty. These patients usually have a familial pattern of delayed puberty that is not secondary to a pathological disorder; puberty is expected to occur spontaneously at a relatively late date. Brief treatment with conservative doses may occasionally be justified in these patients if they do not respond to psychological support. The potential adverse effect on bone maturation should be discussed with the patient and parents prior to androgen administration. An X-ray of the hand and wrist to determine bone age should be obtained every six months to assess the effect of treatment on the epiphyseal centers


  • Metastatic mammary cancer – Testosterone Enanthate Injection, USP may be used secondarily in women with advancing inoperable metastatic (skeletal) mammary cancer who are one to five years postmenopausal. Primary goals of therapy in these women include ablation of the ovaries. Other methods of counteracting estrogen activity are adrenalectomy, hypophysectomy, and/or antiestrogen therapy. This treatment has also been used in premenopausal women with breast cancer who have benefited from oophorectomy and are considered to have a hormone-responsive tumor. Judgment concerning androgen therapy should be made by an oncologist with expertise in this field.


Testosterone Enanthate Injection Information


Weekly totals of 250-1000mg weekly are frequently used, and sometimes more for the highly advanced athlete. Due to the relatively long half life of enanthate (4-5 days), injections are usually administered twice per week. This will allow stable blood levels to be maintained. When the level of steroid tapers down, a new injection is made, keeping everything fairly level. This is unlike sustanon, which requires more frequent injections for the same effect. For a first cycle, 500mg alone of testosterone enanthate, shot two times weekly (Monday and Thursday for example), for 10 weeks along with standard post cycle therapy would be very sufficient for good gains.

Testosterone Enanthate(Primoteston) is one of the most popular used testosterone products on the market today. It is very effective in building muscle, burning fat and gaining strength. It is also cheap and easy to obtain. Testosterone makes the muscles retain more nitrogen, which in turn makes the muscle synthesize proteins better, producing larger muscles.
