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.
