The steroids trenbolone acetate (TbA) and melengestrol acetate (MGA) are licensed as growth promoters for farm animals in several meat-exporting countries. Although many studies have explored their safety for both animals and consumers, little is known about their fate after excretion by the animal. Our study aimed to determine the residues and degradation of trenbolone and MGA in solid dung, liquid manure, and soil. In animal experiments lasting 8 weeks, cattle were treated with TbA and MGA. Solid dung and, in case of trenbolone, liquid manure were collected and spread on maize fields after and months of storage, respectively. Determination of the hormone residues in all samples included extraction, clean-up (solid-phase extraction), separation of metabolites and interfering substances by HPLC (RP-18), and quantification by sensitive enzyme immunoassay. Procedures were validated by mass spectrometry (MS) methods. During storage of liquid manure the level of trenbolone decreased from 1,700 to 1,100 pg/g (17alpha-isomer), corresponding to a half-life of 267 days. Before storage, the concentrations in the dung hill ranged from 5 to 75 ng/g TbOH and from to 8 ng/g MGA. After storage, levels up to 10 ng/g trenbolone, and 6 ng/g MGA were detected. In the soil samples trenbolone was traceable up to 8 weeks after fertilization, and MGA was detected even until the end of the cultivation period. The results show that these substances should be investigated further concerning their potential endocrine-disrupting activity in agricultural ecosystems.
Regardless of the type of cycle or intended purpose most will find 6 weeks of Trenbolone-Acetate use to be the minimal time frame with 8 weeks being far more optimal. You can use it for longer periods but 12 weeks will generally be all the Trenbolone anyone will ever want and should be reserved for more experienced users who understand how their body reacts. The strong majority of Trenbolone-Acetate users will generally find 50mg every other day to be just about perfect, with 100mg every other day being a good dosing for a more advanced athlete and user, especially one looking for more of a bodybuilding type physique. For higher end doses some will choose to go as high as 100mg every single day but most will never need this amount and if they do such an amount is best served towards the end of a bodybuilding contest prep cycle and diet in order to bring in ultimate hardness.
You will find T renbolone-Acetate stacks well with just about any other anabolic steroid imaginable but if there is anything you should stack it with it is some form of exogenous testosterone; the form of testosterone doesn’t matter, long esters, short esters and mixtures are all absolutely fine. Many individuals may also find Cytomel to be a useful addition to a Trenbolone stack as the hormone will slightly lower natural T-3 levels. No, this addition is by no means an absolute must but it can provide some useful benefits especially while dieting.
Once your cycle ends and you are entering into you Post Cycle Therapy (PCT) if the cycle ends with Trenbolone-Acetate and all other steroids are of a small ester form you will be able to begin your PCT in a few short days. This gives Trenbolone-Acetate an advantage over Trenbolone-Enanthate, for if the Enanthate version were being used you would need to wait approximately 2 weeks before PCT began. Remember, the sooner we can start our PCT the better off we’ll be, in-terms of gains kept and our overall health.
Some bodybuilders and athletes use trenbolone for its muscle-building and otherwise performance-enhancing effects. [ citation needed ] Such use is illegal in the United States and many other countries. The DEA classifies trenbolone as a Schedule III controlled substance 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 administered to Russian athletes at the Sochi Winter Olympics consisted of oxandrolone , metenolone , and trenbolone.
