Testosterone can be administered parenterally , but it has more irregular prolonged absorption time and greater activity in muscle in enanthate , undecanoate , or cypionate ester form. These derivatives are hydrolyzed to release free testosterone at the site of injection; absorption rate (and thus injection schedule) varies among different esters, but medical injections are normally done anywhere between semi-weekly to once every 12 weeks. A more frequent schedule may be desirable in order to maintain a more constant level of hormone in the system.  Injectable steroids are typically administered into the muscle, not into the vein, to avoid sudden changes in the amount of the drug in the bloodstream. In addition, because estered testosterone is dissolved in oil, intravenous injection has the potential to cause a dangerous embolism (clot) in the bloodstream.
Grupo Comercial Tarasco (a distributor for Jurox Australia). The change in label may have something to do with the recent controversy in Australia over this country’s high rate of steroid exports to Mexico (and their subsequent diversion to the . black market). Both products can still be found in circulation at this time however, so don’t let this worry you. The Ttokkyo product line has brought home a good share of the Mexican Winstrol ® market by now though, releasing the first 100mg/ml stanozolol injectable and l0mg tablet ever to be produced commercially. Although some complain about the lower viscosity and troublesome nature of the injectable product when it comes to administering it (you will probably need a 21 gauge needle), for most the 100mg dose is just too high to pass up. The 10 mg tablet is also in high demand for those tired of the old low dose/high cost 2mg tabs. With such attention being paid to high dosed products as of late, it is not surprising that two new versions of Ilium’s Stanazolic have hit the market. Their new version of the favored Stanazolic injectable comes in a l0ml vial and carries the same whopping 100mg/ml dose as the Ttokkyo product, and judging by the high quality of the 50mg version is likely to grab a lot of attention itself. The second is a 6mg stanozolol capsule, which comes packaged in bottles of 300. Although not the l0mg dose of Ttokkyo, it is still triple the strength of a normal Winstrol tablet and the only other product currently available to carry over 5mg. In spite of all the Mexican imports however, the Zambon brand preparations from Spain do still seem to be make their way to the States. These products are supplied in 2mg tablets and 50mg water-based injectable ampules. In addition Genepharm has released a generic recently, containing a 5mg per tablet dosage.
Although Winstrol does possess a weaker androgenic strength rating than Testosterone does, androgenic side effects are still a potential risk, though much lower, and may only effect users significantly if they are especially sensitive to androgens. Androgenic side effects can include increased oily skin and acne, hair growth on the body, MPB (male pattern baldness), and BPH (Benign Prostatic Hypertrophy). The use of a 5-alpha reductase (5AR) inhibitor, such as Finasteride, Dutasteride, Proscar, or Propecia will be completely ineffective here, as Winstrol does not convert into DHT.
