Genesis Testosterone Cypionate Injection 10 ml vial (250 mg/ml)

环戊丙酸睾酮

Is a long-acting formulation of 睾酮, indicated for individuals with absent or significantly low hormone levels. Commonly referred to as Depo Testosterone, this esterified version is solely accessible in injectable form. Typically dissolved in sesame or cottonseed oil, it is administered intramuscularly into the buttock, ensuring a gradual release of the hormone for approximately 7-12 days.

The formulation appears as a white, milky powder, insoluble in water yet readily dissolvable in various organic solvents, including vegetable oil.

药理学

The human body naturally produces sex hormones, such as 睾酮, essential for the growth and development of secondary sexual characteristics, including prostate, testes, penis, scrotum growth, body hair, voice changes, and body composition shifts. Testosterone deficiency leads to abnormal secondary sexual traits and growth, making testosterone replacement therapy vital for those lacking this hormone or facing infertility issues.

Indications for Use

环戊丙酸睾酮 is utilized to address conditions where testosterone secretion is inadequate, such as:

• Primary testicular failure
• Pituitary gland failure to release gonadotropins

健美

In the realm of athletics and 健美, 睾酮 and its analogs are frequently employed to enhance physical performance and boost mental focus. Bodybuilders often report heightened energy levels and increased aggression, making it popular among weightlifters and professional wrestlers. Many athletes acknowledge improved exercise performance at intense levels, courtesy of this powerful anabolic agent, which showcases moderate anabolic and strong androgenic properties.

Since the drug requires injection, its effects are not immediate; users may not observe benefits until 3-4 weeks post-administration. Notably, unlike oral testosterone, injected versions remain active in the body longer. Continuous administration for 4-6 weeks can promote muscle mass increases and protein anabolism, although proper caloric intake is necessary for optimal results.

Given its conversion to estrogen within fatty tissues, users may face risks of gynecomastia and water retention. To mitigate these effects, substances like Arimidex or tamoxifen are often incorporated during off-cycles.

During testosterone use, natural testosterone production may be inhibited due to feedback mechanisms affecting pituitary LH levels. Prolonged high doses can impair spermatogenesis; thus, a gradual tapering off is advised to allow the hypothalamic-pituitary axis to recover. Abrupt cessation can result in fatigue, weight loss, and vulnerability to fractures.

禁忌症

Certain individuals should abstain from using testosterone-containing steroids, as they may exacerbate existing conditions, including:

• Allergy to testosterone
• Male breast cancer
• Male prostate cancer
• Pregnant or breastfeeding women
• Individuals with liver, kidney, or heart issues

副作用

When injected at low doses, side effects of 环戊丙酸睾酮 are uncommon. However, long-term usage has been linked to various side effects, most of which are reversible upon discontinuation. Women using testosterone may encounter virilizing side effects that can be permanent. Common side effects include:

• Nausea, vomiting
• Abdominal cramps, diarrhea
• Swelling
• Fluctuations in libido
• Headaches
• Acne, oily skin
• Mood alterations, including anger, depression, insomnia
• Excessive sweating
• 脱发
• 妇科肿瘤

In females, virilizing effects may manifest as:

• Deepening voice
• Hoarseness
• 毛发过度生长
• 阴蒂增大
• Irregular menstrual cycles

The conversion of testosterone to estrogen in fatty tissues can lead to breast enlargement and water retention, often evident after four weeks of use, although gynecomastia remits after discontinuation.

用药过量

Overdose incidents with 环戊丙酸睾酮 are exceedingly rare. While adverse effects aren’t typically acute, excessive doses may induce prolonged illness. Medical consultation is advisable based on the quantity administered.

用量

Clinically, 环戊丙酸睾酮 is delivered through intramuscular injection. Available in strengths of 100mg/ml and 200mg/ml, it should be administered solely into muscle tissue, preferably the buttock, every 7-12 days. Despite the suggestion for weekly injections, some bodybuilders opt for more frequent doses, which can pose risks such as abscesses and skin infections. Frequent rotation of injection sites is essential, avoiding arms or abdomen due to the oily nature of the suspension. Dosages vary from 50mg to 400mg per week, depending on treatment objectives, with bodybuilders typically administering higher amounts of 200mg to 400mg weekly, resulting in gradual absorption into the bloodstream.

控制

环戊丙酸睾酮 is classified as a controlled substance (Class 3) under the Controlled Substance Act, requiring a physician’s prescription for legal acquisition in the USA. Illegal possession, distribution, or sale of this anabolic steroid is strictly prohibited.

检测

Due to its oily formulation, 环戊丙酸睾酮 and its metabolites can be detected in urine for up to 2-3 weeks post-injection, leading many bodybuilders to reserve its use for off-season cycles.

可用性

Most bodybuilders typically acquire 环戊丙酸睾酮 through black market sources; in the USA, original pharmaceutical options are highly regulated and scarce. However, generic formulations are obtainable from regions including Japan, Australia, Mexico, Spain, Brazil, and Thailand. Users can administer doses ranging from 200mg to 1000mg per week, with a vial of 400mg in 2ml costing approximately $20-$40, potentially accumulating to $200 monthly depending on consumption rates. Nonetheless, potential issues with product purity and authenticity are prevalent in the online market.
