CypioJect 250

Testosterone cypionate 200mg/ml

Testosterone cypionate is long-chain ester of testosterone. Used by various athletes in many different competitions, is widely applauded for the best stability, “mild” onset of action and convenient injection frequency – it can be administered once a week. Most often used as base steroid in long steroids cycles, and testosterone replacement therapy (TRT), because of its longest mean half-life among all testosterone esters, that is 6-8 days. Due to this fact, steroid cycle basing on TestoJect 250 should be at least 16 weeks. Increased strength and muscle mass gains are usually observed within 5-6 weeks from first application, but no “radical” effects are to be observed. Other expected effects are the one typical for testosterone itself: increased sex drive, raised energy levels, elevated mood.



Testosterone cypionate a long-chain testosterone ester which presents the same properties as its analog testosterone with the advantage that this molecule has the longest release rate and half-life (6-8 days). Administration of ester derivatives of testosterone like testosterone cypionate generates an increase in serum testosterone to levels reaching 300% from the baseline within 48 hours of administration, and circulate throughout organism for as long as 10-14 days. Therefore, injections should be done once every 5-8 days, thus making it the most “comfortable” of all steroids.

Traits & effects

CypioJect 250 is most known for its mild onset of effect; that is, increased strength, energy levels and libido are noticed at 5-6 weeks following first injection. Muscle mass gained while using this specific testosterone ester is most often regarded as “stable”, while cycling itself remains “convenient” – because of rare injections required. What’s worth notice is that it is one out of three testosterone esters approved by FDA (U.S Drug administration), where it is broadly used in transgender therapy. Usually used in long (16 weeks at least) and very long (TRT) 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: 150-250mg – E6D (every sixth day)

Intermediate: 200-400mg – E6D

Advanced: 300-500mg – E6D

Elite: 600+ mg –E5D


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.
