Tren is by far the worst for the liver not to mention the side effects like night sweats and tren cramps. I am using DHB for the first time and I am impressed with the results so I am biased and say DHB is best. It will thicken your blood so something to keep an eye on, Just stay hydrated and do cardio and then if its still too high then donate some blood.

"Boldenone can cause estrogen-related side effects (like gynecomastia or water retention) because it converts to estrogen, albeit less than testosterone. DHB, being 5α-reduced, does not aromatize, which can lead to a "drier," harder muscle gain appearance but also potentially different side effects."

Im no expert but id say Tren is the worst effect on liver and kidneys, no question.

Boldenone will probably increase your red blood count more.

It depends what my stats/goals are. I wont ever be using tren again. The only reason I see for any human to take tren is if youre going for the Olympia.
I love tren, and ive abused it alot. If I could go back id never have taken it.

Stick with either dhb or eq.
