With regard to activity at other receptors, many have written regarding theories of progestagenic activity of trenbolone. Where legitimate trenbolone is used, practical experience shows no detectable effect with regard to water retention or gynecomastia. Veterinary literature reports no detectable progestagenic effect. And if this were not enough, recent cell culture research shows progestagenic potency to be only about 1% that of progesterone itself, which would not be an important amount.

For these reasons, I would make no decisions against trenbolone from fears of claimed progestagenic activity. It is a very well-proven compound in bodybuilding, including in contest-prep situations where an actually-progestagenic compound would be very unsuited.

“Tren Cough”

The final unusual thing about trenbolone to be mentioned is “tren cough.” This is a very brief episode which may occur with only a small percentage of injections, perhaps not even 1%. It can be very unpleasant for a minute or two. The most likely explanation is from irritant effect of a small amount of the oil preparation entering the bloodstream, not by direct injection into a vein but by leakage into a small blood vessel that was cut as the needle entered. There is no evidence of lasting harm from this.
