Should Trenbolone Be Stacked with Testosterone?

Ask Bill Roberts questions about anabolic steroids and bodybuilding

Q: How do you feel about using trenbolone by itself? Many people say this is a bad idea. But what is the rationale for stacking trenbolone with testosterone? How would you suggest combining trenbolone and testosterone or trenbolone with other anabolic steroids?

A: There’s more than one approach.

One approach is to use an amount of trenbolone that stays within the comfortable range for the individual user and likewise uses only an amount of testosterone that the user finds suitably mild in terms of side effects. An example might be using 50 mg/day of trenbolone acetate (or a total of about 350 mg/week of trenbolone enanthate) and 250-500 mg/week of testosterone.

Another approach is to supplement fairly strong testosterone use, such as 1000 mg/week, with say 50 mg/day of trenbolone acetate.

Still another approach is to go strong with the trenbolone, which might be 75 or 100 mg/day, use Anadrol and perhaps Winstrol as well, and add testosterone mostly for the sake of the resulting estrogen. In this case the testosterone dose would be 100-200 mg/week.

Here there will be a slight increase in anabolic effect from that small amount of added testosterone, but the real reason for use in that example is that the chosen oral steroids don’t aromatize, and neither does trenbolone.

When no aromatizing steroid is taken, and doses are high enough to yield complete suppression, and HCG is not taken, estradiol levels usually drop too low.

Taking a modest amount of testosterone such as 100-200 mg/week avoids this problem.

Replacing the natural testosterone with a like amount of injected testosterone avoids undesired changes in estrogen level.

But the direct problem that would exist otherwise is not lack of testosterone (which isn’t a problem provided other androgens cover all of its activity) but lack of estrogen.

Dianabol, for example, could also solve the problem.

With say a trenbolone/Dianabol stack, then there is no need for testosterone. The two steroids cover all the bases for activity of androgen steroids, and aromatization of Dianabol covers the need for a normal degree of estrogenic activity (or possibly too much, depending on dosage and individual sensitivity.)

I know some find it heretical to use no testosterone, but actually it can work extremely well, if both the stacking consideration of having Class I and Class II steroids is taken into account and estrogen effect is kept at an appropriate level. Again, the trenbolone/Dianabol stack is a classic example of this.

Basically the drugs combine very well. Where a user is not particularly sensitive to insomnia or night sweats (a less common problem is anxiety) with trenbolone, that drug can efficiently take care of, if desired, all of the Class I part of a stack. Testosterone, having mixed activity, can either be used as the only additional steroid to fill out the stack, or as one of the steroids used for that purpose.

    I have been considering using Tren to build muscle. I have many concerns: being that I’ve never tried anything like this will the use of stacking Tren and diabol make me irritable? Any comments would be helpful.

    Thank you.
