Finally, it must be mentioned that any particular ester of Trenbolone does not require a similarly estered anabolic steroid to be stacked with it (for example, Trenbolone Enanthate stacked with Testosterone Enanthate). It is a perfectly fine and safe practice to be able to combine, for example, Trenbolone Acetate and Testosterone Enanthate (instead of Testosterone Propionate ) in Trenbolone cycles. These combinations present no problems and actually work well, but every individual curious about these combinations must always be aware that proper timing, half-life, and injection frequency varies with each of these compounds. The only reason why many individuals prefer to stack Testosterone Enanthate with Trenbolone Enanthate , for example, is because of the convenience aspect and ease of administration frequency and timing (as both compounds are identical in half-life).
Combined preparations . A number of trials have been carried out with implants containing two hormones. The combination of an oestrogen with an anabolic steroid, or with progesterone, has met with the greatest responses. Synovex-S has consistently increased gain as well as FCE, with responses averaging about 20% and 17% respectively (20, 21, 22, 34, 35, 36, 37, 42, 43, 44, 45, 46, 47, 48). Hexoestrol + TBA (usually 30 or 45 mg hexoestrol + 300 mg TBA) has resulted in marked increases in gain (24, 25, 26, 29, 49, 50, 51, 52, 53), of the order of 30% and in FCE (25, 49, 50, 51, 53) of the order of 20%. Oestradiol-17β + TBA (20/140 mg) has given similar results (27, 28, 37, 54, 55), as has Zeranol + TBA (36/300 mg), also recently tested (27, 37, 38, 39, 40, 41, 56).
