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.
Winstrol (Stanozolol) is an Anabolic Steroid that was derived from Testosterone in 1962 by Winthrop Labs . The original purpose of this steroid was to help treat people suffering from anemia, it is also often used for veterinary purposes. This high anabolic, low androgenic steroid does not bind to the androgen receptor. For this reason Winstrol is considered a weak steroid in terms of its muscle building properties, it does however cause great increases in strength. Stanozolol is also a popular steroid for females due to its low androgenic properties it makes it a safer choice as side effects such as voice deepening and facial hair are a lower risk when compared to steroids such as Dianabol . This doesn’t mean females should use Winstrol as irreversible masculine side effects are still a risk.
