What is TrenMix 150?
TrenMix 150 is a ready-made oil solution of several trenbolone esters with a combined 150mg of trenbolone per ml. One vial holds 10 ml and needs no mixing. The manufacturer does not state the exact ester ratio; such mixes usually combine short and long esters.
Trenbolone is one of the most potent anabolic steroids there is. It comes from livestock use and was never approved for humans. Up front: the side-effect profile is harsh and the blend is nothing for beginners.

Comparison
Single esters and blends
Always the same trenbolone at the same receptors, only the esters differ, as stated in the TPD lexicon. Tap a card to open its entry.
The ester only changes how fast trenbolone leaves the depot. There is no human study comparing the esters. 12
How it works
Trenbolone binds the androgen receptor much more strongly than testosterone and drives muscle growth and strength with little water retention. It is not aromatized to estradiol but acts on the progesterone receptor, which can favor prolactin effects. Your own testosterone production is strongly suppressed without trenbolone replacing it.
The ester mix only controls release: short esters act fast, long ones keep levels up. Since the ratio is unknown, the half-life cannot be stated precisely. In a research context trenbolone is usually combined with a testosterone base, which this blend does not contain.
Where it acts
Where trenbolone acted in studies
Tap a point or a card. Grey = seen in studies, mostly in rats or by survey.
- Brain and mood
Irritability, mood swings and aggression more common in surveys than with other anabolic steroids14
Observed in trials - Heart
Concern about the heart in 54.4% of men with trenbolone, 31.2% without (survey)14
Observed in trials - Blood lipids
HDL cholesterol -57%, LDL cholesterol -78%, triglycerides -62% (rats)11
Observed in trials - Skeletal muscle
Muscle fibre cross-section +94%, satellite cells +178% after castration (rats)10
Observed in trials - Bone
Bone density fully preserved after castration, femoral neck 28% stronger (rats)9
Observed in trials - Fat tissue
Fat mass -37% in 6 weeks, control animals +34% (rats)11
Observed in trials - Hormone axis and prostate
Own sex hormones suppressed, prostate benignly enlarged (rats)11

Injection
Intramuscular into the glute, thigh or shoulder, with a thick needle to draw up and a thin one (23G to 25G) to inject. Disinfect the stopper and the site first and rotate sites regularly. Aspirating first and injecting slowly lowers the risk of tren cough, a brief coughing fit right after the injection.
Trenbolone and a possible short ester irritate subcutaneous fat. Subcutaneous use therefore only at very small volumes and only if well tolerated, otherwise intramuscular.
What the research shows
Trenbolone is described as a very potent anabolic with reduced androgenic and estrogenic activity; the evidence comes almost entirely from animal studies (Yarrow, 2010). Performance doses in humans are not covered by any controlled study. There is no study of this particular ester mix.
Reviews and observational studies of anabolic steroids show shifted lipids (Achar, 2010), lastingly higher blood pressure with a stiffer aorta (Rasmussen, 2018) plus, with long-term use, weaker heart pumping function (Baggish, 2017). In a prospective cohort every one of 100 users had at least one side effect (Smit, 2020).
Study results
What the trials measured
Interactive: switch tabs, tap points, show or hide arms. Arms are named relative to each other, no dosing advice.
Muscle after castration (rats)10
Increase compared with castrated rats without hormone after 29 days, pelvic muscle
Rats, 41 animals in four groups. Testosterone was given in a much higher amount than trenbolone. Despite more myostatin the muscle grew under both hormones.
Prostate (rats)89
Change in prostate mass compared with sham-operated rats
Low trenbolone levels kept prostate and haemoglobin at the sham level. In the older rats the value -20 is not statistically significant, testosterone nearly doubled the prostate there. Not transferable to humans.
Body and blood lipids (rats)11
Non-castrated rats, 6 weeks of trenbolone via a pump under the skin
12 rats. The control animals gained fat over 6 weeks, under trenbolone fat mass fell. The prostate grew benignly, the body's own sex hormones were suppressed. Rat values for blood lipids do not transfer to humans.
Heart and circulation in anabolic steroid users567
Observational studies, anabolic steroids in general, not only trenbolone
Shares in percent, for pumping function the mean ejection fraction. In the HAARLEM study every one of the 100 men had at least one side effect, four had a serious event. There is no study on the blend itself.
Research status
Where the research stands
There is no registered human trial of trenbolone. The data on TrenMix 150 come from animal studies, lab experiments and surveys of users. As of 26 Oct 2026. 16
- Preclinical Rats: muscle, bone, fat and prostate
- Phase 1 no registered trial
- Phase 2 no registered trial
- Phase 3 no registered trial
- Approval not yet
So far there is no registered trial in humans. 16
Side effects
- Prolactin: trenbolone can cause prolactin effects, with libido and erection problems. Add prolactin to the bloodwork.
- Lipids: HDL drops sharply and LDL rises. Trenbolone is considered especially unfavorable here.
- Blood pressure and heart: blood pressure and resting heart rate go up, endurance and breathing under load suffer. Measure regularly.
- Sleep: trouble falling asleep, restless sleep and night sweats are typical.
- Mood: irritability, restlessness and aggression are reported often.
- Hormone axis: your own testosterone production is strongly suppressed. Without a testosterone base, loss of libido and poor wellbeing are likely.
- Other: acne, oily skin, hair loss if predisposed.
Blood pressure, lipids and prolactin should be checked before, during and after a cycle.
Tolerability
Self-reported concerns in a survey
Out of 100 men, how many reported the concern in an online survey. Self-report, no medical measurement, no placebo.
| Event | With trenbolone (237 men) | Other anabolic steroids without trenbolone (909 men) |
|---|---|---|
| Concern about the heart14 | 54% | 31% |
| Hair loss14 | 43% | 28% |
| Concern about the liver14 | 42% | 22% |
| Gynaecomastia14 | 33% | 21% |
| Restlessness and irritability14 | 29% | 13% |
| Decreased sexual function14 | 25% | 15% |
| Anger and aggression14 | 21% | 9% |
Values from the tables of the study (full text), rounded in the chart. The trenbolone group also took oral anabolic steroids far more often (79.7 vs 38.4 percent), so a concern cannot be assigned to one compound with certainty. Several concerns occurred together more often with trenbolone.14
Storage
Store at room temperature, in the dark and in the original packaging, out of reach of children. Do not put it in the fridge, because cold makes the compound crystallize out of the oil. If you see crystals, warm the vial in your hand or in warm water and swirl until the solution is clear again. Disinfect the stopper before every draw.
