Recent trials with beef-producing heifers have mostly been based on the use of an androgen, although oestrogens have been tested, alone or in combination. Thus, zeranol has been reported to increase gain (62, 63), while in other trials no response has been observed (37, 62). TBA administered alone (300 mg) has led to increases in weight gain and FCE of the order of 36% and 25% respectively (24, 27, 37, 64, 65, 66, 67, 68, 69, 70). In other trials, combinations of an oestrogen with TBA (68) or testosterone (62) have yielded significant growth responses. In general, it appears that the effect of TBA alone in heifers corresponds closely to the effect of combined oestrogen/TBA implants in steers.
Precision Gear Works offer two versions of this drug, one being Tren 150 which is dosed at 150mg/ml and contains the Enanthate ester and Tren-Ace 80 which is dosed at 80mg/ml of the Trenbolone acetate ester. Dosage on the acetate ester ranges from around 40mg every day or 80 every other day right up to 80mg every day or 160mg every other day, some users have reported dosages at 200mg ED and, while I think that is just crazy if you compare the anabolic/androgenic ratio to a powerful hormone such as testosterone you will see why. If you are using the Enanthate base you will be looking at around at around 2ml per week, which would be around 300mg of the drug. I would suggest starting off on the Ace version and seeing how your body responds to Tren, the last thing you want is a long ester at work when you start to develop some really nasty side effects.
