TestoJect 250

Testosterone enanthate 250mg/ml

TestoJect 250 is medium-chain ester of testosterone. Used by various athletes in many different competitions, probably most well-known for its stability, “mild” onset, action and convenient injection frequency. Most commonly used as base compound in medium-long steroid cycles because of long mean half-life of 4-5 days. Due to this fact, steroid cycle basing on TestoJect 250 should be at least 10 weeks. Increased strength and muscle mass gains are usually observed within 5-6 weeks from first application, as well as other effects typical for testosterone e.g. increased sex drive, raised energy levels, elevated mood.



Testosterone enanthate is a medium-chain testosterone ester which presents the same properties as its analog testosterone with the advantage that this molecule has a longer release rate and half-life (4-5 days). Administration of ester derivatives of testosterone like testosterone enanthate generates an increase in serum testosterone to levels reaching 500% from the baseline within 24 hours of administration. Therefore, injections should be done within maximum 4-5 days gap.

Traits & effects

TestoJect 250 is most known for its mild onset of effect; that is, increased strength, energy levels and libido are noticed at 4-5 weeks following first injection. Muscle mass gained while using this specific testosterone ester is most often regarded as “stable”, and side effects seem to be less severe than with any other testosterone form. What’s worth notice is that it is the only testosterone ester used in clinical hypogonadism treatment, meaning that its effects are broadly examined and known. Usually used in long (8-10 weeks at least) and very long (up to 20+) steroid cycles to keep high testosterone levels during intense workout period, alongside with many other steroids applied periodically.

Dosage & administration

Dosage is strictly dependent on one’s experience, desired effect and other steroids/drugs being used, but most often presented schedule is:


Beginner: 100-150mg – E4D (every fourth day)

Intermediate: 150-350mg – E4D

Advanced: 200-400mg – E3D

Elite: 400+ mg –E3D


Side effects & precautions

Side effects are the ones typical for testosterone itself, that is, increased irritability, sex drive, excess hair growth, acne, skin rash, fluid retention. Men prone to pattern baldness ought to be aware that it may worsen or even initiate the process, as the DHT level throughout blood and tissue rise during the cycle. Testosterone cypionate side effects – in contrary to other esters – seem to be less severe, hence it is most common choice of elite athletes and professional bodybuilders, where long-term or permanent steroid use affects health to the point when it becomes a serious issue.

Testosterone is also known for its feminizing effects e.g. growth of breast tissue (gynecomastia), redistribution of facial and body subcutaneous fat, prostate swelling, unusual sweating, fluid retention. Therefore, it is recommended to include anti-estrogen drug in cycle in case if any one of mentioned before is observed. Not only will it improve overall aesthetics and comfort during the cycle, but also prevent condition from worsening. Please be aware, that some of these, especially growth of breast tissue, if left untreated can remain permanent.

Testosterone enanthate can be used as a standalone steroid, but because of the length of the cycle, most often other steroids/drugs are applied. Below we present you a list of other steroids being most often used with TestoJect 250
