Injectable steroids are injected into muscle tissue, not into the veins. They are slowly released from the muscles into the rest of the body, and may be detectable for months after last use. Injectable steroids can be oil-based or water-based. Injectable anabolic steroids which are oil-based have longer half-life than water-based steroids. Both steroid types have much longer half-lives than oral anabolic steroids. And this is proving to be a drawback for injectables as they have high probability of being detected in drug screening since their clearance times tend to be longer than orals. Athletes resolve this problem by using injectable testosterone early in the cycle then switch to orals when approaching the end of the cycle and drug testing is imminent.
Common (1% to 10%): Sinusitis, nasopharyngitis, upper respiratory tract infection, bronchitis
Uncommon (% to 1%): Cough, dyspnea, snoring, dysphonia
Rare (less than %): Pulmonary microembolism (POME) (cough, dyspnea, malaise, hyperhidrosis, chest pain, dizziness, paresthesia, or syncope) caused by oily solutions
Frequency not reported: Sleep apnea
Postmarketing reports: Chest pain, asthma, chronic obstructive pulmonary disease, hyperventilation, obstructive airway disorder, pharyngeal edema, pharyngolaryngeal pain, pulmonary embolism, respiratory distress, rhinitis, sleep apnea syndrome [ Ref ]
I completely agree with you, Kyle. Whenever exogenous Testosterone is stopped – whether it was being taken for TRT or cycled for bodybuilding – some kind of ‘PCT’ (Post-Cycle Therapy) should be utilized to help ‘re-awaken’ your HPG axis after it had been shut down by Testosterone replacement or cycling. It is important to note that such PCT is NOT taken forever! The use of HCG and either Tamoxifen or Clomid will help greatly in reducing withdrawal symptoms by bolstering your body’s natural Testosterone production and greatly speeding up recovery time (the time it takes for your body to start creating its own testosterone again without any external substance).
