Trenbolone Acetate – Stacks, Doses, Side Effects and Alternatives


Trenbolone is an injectable anabolic steroid that works to increase muscle mass, weight loss, strength and recovery. It is a relatively safer choice for athletes looking to achieve those goals and can bring about significant gains. It was actually created for use on livestock to increase the muscle mass and appetite of cattle.

Trenbolone is sometimes referred to as ‘Fina’ due to its connection to Finaplix H pellets – ear implants that were originally used as the source of the substance.

Mechanisms of Action

Like Dianabol and many other anabolic steroids, Trenbolone works by binding to the androgen receptor. It has an affinity that is five times higher than testosterone and once metabolized it has an additional benefit of increasing ammonium ion uptake which boosts protein synthesis. This means that it can help to increase the muscles’ ability to use protein and amino acids to stimulate hypertrophy.

Trenbolone also has the benefit of decreasing the rate of catabolism (preventing muscles from being burned) and stimulates appetite. All of this makes it a great choice for bodybuilders looking to bulk. At the same time, it also leads to elevated fat burning helping to make the muscle appear leaner and more defined.

Benefits and Uses

When using Trenbolone, athletes can expect to experience increased muscle gains, energy in the gym, fat loss and recovery. This results in the rapid formation of a highly lean and developed musculature and more swollen looking muscles.

Of course to see these effects, the athlete must still put the work in themselves as well in terms of their workout routine and their diet. There is no such thing as a ‘silver bullet’ when it comes to muscular development, so you must ensure you put the effort in.

The approach that steroid users take to workouts should be slightly different from the approach taken by natural athletes. For starters, steroid users will be able to recover faster, which means they can train the same muscle groups more regularly with a decreased risk of overtraining. This essentially means that athletes can accelerate their muscle gains yet further.

Steroid users should also look to increase their time under tension to encourage hypertrophy. To see the maximum muscle growth, you want to be looking at rep ranges of 12-15 rather than the usual 8-10. Lighter weights can be used and a slower tempo to really encourage pump and subsequent growth.

We also mustn’t forget the appetite-boosting benefits of Trenbolone. As anyone who has tried to stick to a diet of 4,000 calories made mostly of protein knows, eating enough to stay big is hard. Trenbolone makes this a little easier and is an indirect way in which it can further enhance progress.

One of the interesting benefits of using Trenbolone over other steroids is that some bodybuilders believe it doesn’t get metabolized by aromatase or 5a-reductase. What this simply means, is that it doesn’t get converted into estrogen and therefore shouldn’t run the risk of gynecomastia (breast development) or other feminization problems. This is partly because Trenbolone doesn’t need to be converted to DHT (dihydrotestosterone) to exert its effects).

Similarly, though kidney toxicity has been suggested, it hasn’t actually been proven and this may remove one more risk associated with steroid use.

Side Effects and Downsides

Trenbolone works by raising testosterone and this means that it can carry with it all of the side effects associated with elevated testosterone. Such side effects include acne, hair loss, insomnia, sweating and roid rage. Anecdotally, there is a relatively high number of reports online from users who found that Tren led to anger and this can have a pronounced and negative impact on your relationships – that is something worth considering before using.

Here is a report from one steroid user from a bodybuilding forum:

“Tren made me strong as hell and extremely vascular…but be careful, it also made me angry. Tren is the only steroid that has caused this type of reaction in me…people on tren are not fun to hang out with…but the sh*t works…you decide.”

The ‘Tren cough’ is another common (and irritating) side effect.

Another danger with Trenbolone is that it can suppress natural testosterone production – a risk with any anabolic steroid that works normally by elevating testosterone unnaturally. This makes it very important to use some kind of post cycle therapy, which may be something like hCG – Human Chorionic Gonadotropin – or chlomid (a fertility medicine that stimulates the pituitary gland).

If this isn’t managed correctly, users may suffer from low testosterone post cycle, leading to depression, muscle loss, weight gain and impotence. This can then lead to the need for HRT, or hormone replacement therapy. Potentially indefinitely.

Another downside to Trenbolone use is that on it’s own it is not as potent as other choices like Dianabol or Anadrol. This means that you may not see the same rapid muscle development as you would with those oral steroids.

And while injectable steroids are less liver toxic than orals, they nevertheless are painful, complicated and can leave scars. This is the reason that many people will choose Dianobol or Anadrol over Trenbolone, despite the latter being safer.

Cycles, Doses and Stacks

If you decide you want to try Trenbolone despite the significantly associated dangers, then you will likely start with a dose of around 35mg a day as a beginner. This is a highly anabolic choice, so if you have no experience with steroids it’s not recommended to go above this number. More advanced users may go as high as 100-150mg a day, though this of course brings an increased risk of side effects.

Tren is normally used for cycles of around 8 weeks, which is a common length for many steroids. If you want to see enhanced benefits, then Tren stacks very well with Anadrol which supports the protein synthesis aspect of this steroid. It can also be used with testosterone, or potentially Dianabol which is an oral steroid with similar mechanisms of action.

Safer Alternatives

However, it is actually much smarter to avoid Trenbolone use altogether if you value your relationships and your natural testosterone levels. The good news is that you can still see amazing benefits by using safer alternatives – and specifically the wonderful T-Bal 75 from Crazy Mass. This product utilizes naturally occurring vitamins, minerals and herbs to encourage the natural increase in testosterone and protein synthesis. In short, it yields the same results but with none of the dangerous side effects. And it’s completely legal!

T-Bal 75 is an important part of the Bulking Stack that a lot of bodybuilders use to gain lean and hard muscle quickly. What makes this stack so powerful is that it combines Trenorol with alternatives for steroid Dianabol or methandrostenolone, steroid Deca Durabolin or nandrolone decanoate and a powerful testosterone booster. This stack has become a massive hit since it can help you gain 20-30 pounds of lean muscle in just an eight-week cycle. 

For these reasons, you might find that Trenbolone has some benefits when it comes to fat loss but these will likely be outweighed by the negatives. There are much better options out there for losing weight and if you’re interested in bulking then you might still find that Trenbolone is overly dangerous. In this latter scenario, something like T-Bal 75 from Crazy Mass will be a much safer option that still offers profound benefits.
