Stanozolol appears to offer less hepatic stress than an equivalent dose of Dianabol (methandrostenolone). Studies giving 12mg of stanozolol per day for 27 weeks failed to demonstrate clinically-significant changes in markers of liver function, including serum aspartate amino-transferase, alanine amino-transferase, gamma-glutamyltransferase, bilirubin, and alkaline phosphatase. 621 Relative hepatotoxicity increases as the dosage escalates, so hepatic dysfunction should still be a concern. In rare instances, high doses (alone or in combination with other steroids) have been implicated in cases of serious life-threatening hepatotoxicity in bodybuilders. Injectable stanozolol has also been implicated in severe hepatotoxicity in an otherwise healthy bodybuilder, 622 and should not be used as an alternative medication when liver toxicity precludes oral stanozolol use.
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.
Some bodybuilders and athletes use trenbolone esters for their muscle-building and otherwise performance-enhancing effects.  Such use is illegal in the United States and many other countries. The DEA classifies trenbolone and its esters as Schedule III controlled substances under the Controlled Substances Act .  Trenbolone is classified as a Schedule 4 drug in Canada  and a class C drug with no penalty for personal use or possession in the United Kingdom .  Use or possession of steroids without a prescription is a crime in Australia .  The infamous "duchess" cocktail allegedly administered to Russian athletes at the Sochi Winter Olympics consisted of oxandrolone , a metenolone ester, and a trenbolone ester.
