Trinabol is a combination of three esters of trenbolone. The presence of the acetate ester allows trinabol to display a rapid initial physiological response. The other two esters, which release at slower rates, prolong the physiological response with a relatively flat absorption curve over the duation of the injection life-cycle. Trinabol has a great effect on promoting protein synthesis, as well as creating a positive nitrogen balance. It is an appetite stimulant and improves the conversion of proteins. In laboratory tests, it has been demonstrated that trenbolone acetate increases protein and decreases fat deposition. It has proven to be an excellent product for promoting size and strength in the presence of adequate protein and calories, promotes body tissue building processes, and can reverse catabolism. Trenbolone is a steroid having the advantages of undergoing no adverse metabolism, not being affected by aromatase or 5alpha-reductase; of being very potent Class I steroid binding well to the androgen receptor; and having a short half life, probably no more than a day or two though I don’t believe this has been measured. Fifty milligrams per day of Trenbolone is a good dosing for someone on his first cycle or someone who is as yet less than, say, 20 pounds over his natural limit; while 100 mg/day may be preferred by the more advanced user who has already gained more than this. These doses are assuming that trenbolone is the only Class I steroid being use. There really is no need to stack another – testosterone being the only sensible exception – but if another is stacked then the amount of trenbolone may be reduced accordingly.
