I agree with Mexico - even the experienced ones don't need anymore than just 250 mgs of tren. Besides, it is also very desirable to keep the test dosage higher than tren in order to avoid any libido problems. The above mentioned dosages are very good, and you will grow like hell.
Also, don't forget about the ancillaries, such as Aromasin, which should be used from the first day of the cycle, and Cabergoline on hand in case prolactin raises due to trenbolone use. Also, it would be great to add in there some Cardarine GW-501516, as it has a proven ability to greatly reduce trenbolone's side effects, and improve its effectiveness.
After the cycle make sure to run a proper PCT.
