Somatrop-Lab Testosterone Propionate 10 ml vial (100 mg/ml)

테스토스테론 프로피오네이트

Testosterone propionate, a popular choice among bodybuilders alongside 테스토스테론 사이피오네이트 and 테스토스테론 에난테이트, stands out due to its rapid onset and shorter duration of action. Released from the injection site within 3-4 days, it maintains a presence in the bloodstream for 24-48 hours. This brief action window often leads to milder side effects compared to other formulations. Testosterone propionate retains its potency, functioning as a mild anabolic agent with moderate androgenic properties. Users typically experience results within 3-5 weeks, but no anabolic steroid can dramatically transform the body in less than this timeframe. Long-term use can lead to side effects, hence a usage period of no more than 4-6 weeks is advised.

약리학

Testosterone plays a crucial role in the normal development of male sex organs and the maintenance of secondary sexual characteristics. It influences the growth of the prostate, testis, seminal vesicles, penis, and scrotum while significantly contributing to overall body growth. Although classified as an androgen, testosterone also exhibits notable anabolic properties, enhancing protein synthesis and promoting a positive nitrogen balance when paired with a calorie-rich diet. Additionally, it can stimulate red blood cell production by enhancing EPO synthesis in the kidneys, improving oxygen transport. Prolonged usage inhibits gonadotropin release from the pituitary through negative feedback, potentially affecting spermatogenesis.

복용량

Testosterone propionate is rapidly released following intramuscular injection, lasting up to 48-72 hours. This formulation is an esterified testosterone intended solely for intramuscular administration, with its esterification extending its action duration. It appears as a clear, colorless to mildly yellow suspension in sesame oil. Some athletes report discomfort when injecting testosterone propionate into the gluteal area; this may stem from using large volumes or developing abscesses. To minimize discomfort, smaller volumes should be used, and injection sites should be rotated. For novice bodybuilders, a starting dose of 50 mg/day is recommended, with some opting for 50-100 mg/day, while others may mix various formulations. Limit treatment duration to 4-6 weeks to allow recovery of the hypothalamic-pituitary axis and testes. During the washout phase, many athletes take Nolvadex (tamoxifen) to mitigate estrogenic side effects.

표시

In Europe, testosterone propionate is used to address conditions characterized by testosterone deficiency, including:

• primary hypogonadism due to testicular injury
• hypogonadism resulting from pituitary GN release failure
• 사춘기 지연
• weight gain in cachectic hospitalized patients

Treatment is often prolonged until secondary sexual characteristics develop adequately.

기간

Treatment with testosterone propionate is contingent upon age, sex, diagnosis, treatment responses, and potential side effects. Administration should occur in the buttock muscles, avoiding subcutaneous injections. Rotate injection sites to prevent abscesses, or consider thigh injections. The maximum dosage should not exceed 100-400 mg per month to limit side effect onset. Always inspect the drug before administration; it should appear clear or colorless-yellow. Any particulate matter signals expiration or inactivity. Treatment duration typically ranges from 1-2 months, and the drug should be stored at room temperature.

보디빌더

Testosterone propionate is commonly utilized during the off-season by bodybuilders but is best avoided during active sports seasons. This steroid has both anabolic and androgenic properties; however, effects may take 3-4 weeks to manifest. Many bodybuilders stack it with other anabolic hormones like GH/thyroxin. As testosterone converts to estrogen in fatty tissues, users may experience breast enlargement and water retention. Typical dosages for muscle mass and strength gains range from 25-400 mg/week. Beginners should start with lower doses to mitigate potent side effects. Gradual increases in protein mass can be expected, alongside improved performance due to stimulated red blood cell production. Testosterone propionate is favored among bodybuilders, although its availability can be limited. Reports indicate its potential to promote health, enhance exercise performance, and achieve a positive nitrogen balance; however, dramatic water retention may necessitate diuretic use. To prevent breast enlargement, it’s common to cycle testosterone propionate with drugs like 아리미덱스 or tamoxifen, with a typical cycle lasting 4-6 weeks followed by a break during which Arimidex may be utilized.

여성

Prolonged usage of any testosterone analogue can produce virilizing effects in women, including voice deepening, excess hair growth, irregular menstrual cycles, mood changes, and clitoral enlargement. Immediate cessation upon noticing virilizing symptoms is crucial, as some effects may not be reversible after stopping the steroid.

부작용

As with all anabolic steroids, testosterone propionate may cause some side effects, generally mild and manageable. A majority of users experience side effects after 2-4 months, with common issues including:

• 불규칙한 월경 주기
• 정력 강화 효과
• 깊어지는 목소리
• 음핵 확대
• 여성형 유방증
• 고통스러운 음경 발기
• hair loss, oily skin, acne
• 수분 유지
• nausea and vomiting
• 황달
• rare liver cancer
• mood changes, depression, anxiety, headaches
• 혈청 콜레스테롤 증가

While most side effects are reversible, breast enlargement and some virilizing effects may persist. Using estrogens to mitigate virilization side effects may not always be effective.

경고

Caution is advised when using testosterone in individuals with:

• 유방암 및 고칼슘혈증
• 간 기능 장애
• 전립선암
• cardiovascular issues

Isolated cases of dry cough and breathing challenges after testosterone propionate injection have been reported, possibly linked to the oil-based formulation or contaminants. Regular liver enzyme and blood hematocrit checks are recommended for all testosterone users to ensure normal levels.

법률

Under the Controlled Substances Act, testosterone propionate is classified as a Class 3 drug and is not legally available in the USA.

탐지

This compound remains detectable in the body for an extended duration. Current testing methods can identify testosterone or its metabolites in urine for 3-4 weeks post-use, with hair tests capable of detecting traces 2-4 months later if excessive use is suspected. However, bear in mind that testing for testosterone propionate is imperfect, with around 50% of users potentially going undetected based on testosterone/epitestosterone ratios.

비용

Legal access to testosterone propionate is challenging, leading many bodybuilders to source it from the black market. Generic formulations from Europe and Mexico are often available but can be expensive, with a 250 mg vial costing between $10-$40. Increased regulation by the DEA over the past two decades has resulted in counterfeit products; therefore, exercising caution during purchases is paramount.
