Profile of Dihydroboldenone Cypionate (1-Testosterone)

The dihydroboldenone cypionate, known as 1-Testosterone, is an anabolic steroid belonging to the family of dihydrotestosterone (DHT) derivatives. It acts as the 5-alpha-reduced form of boldenone (Equipoise) and shares structural traits with methenolone (Primobolan).
The main structural difference lies in the absence of the 1-methyl group, which appears in Primobolan to improve oral bioavailability.

Dihydroboldenone cypionate counts as a potent non-estrogenic anabolic. Lab trials point to an anabolic activity rated at twice as much as testosterone propionate, alongside an equivalent androgenicity level. This yields an estimated anabolic-to-androgenic ratio hovering around 2:1, marking it as a powerful compound.

Bodybuilders value dihydroboldenone cypionate for its capacity to drive solid, lean muscle gains, avoiding heavy water retention or estrogenic side effects.

Chemical Structure and Biological Characteristics

Dihydroboldenone cypionate is a direct derivative of DHT carrying an extra double bond between carbons 1 and 2 (1-ene). This specific structural modification helps to:

• stabilize the 3-keto group

• increase anabolic effectiveness

• reduce estrogen conversion

Due to these traits, researchers classify the compound as non-estrogenic. Gynecomastia, water retention, and estrogen-mediated fat accumulation do not usually appear during use.

Muscle Gain Characteristics

The results delivered by dihydroboldenone cypionate consist primarily of lean, dense muscle mass, driven by tissue growth rather than subcutaneous fluids.
Athletes turn to it during cutting phases when:

• Muscle separation remains a priority

• Water retention stays minimal

• Rapid weight gain is not the goal

Thanks to the significant increase in strength, it can still be used in cycles of controlled mass

Cholesterol and Cardiovascular System Impact

Dihydroboldenone cypionate impacts the lipid profile more heavily than testosterone and nandrolone, largely because it does not aromatize.
Even so, its effects remain milder than those caused by many 17-alpha-alkylated steroids.

Like all anabolic steroids, it can:

• lower HDL cholesterol

• raise LDL cholesterol

• alter blood pressure

• promote left ventricular hypertrophy

Improper or prolonged use will raise cardiovascular risk.

Tolerability and Specific Usage Considerations

Dihydroboldenone cypionate is known to be intrinsically irritating. Reported local effects include:

• discomfort or pain at the injection site

• reddening of the tissues

• skin irritation from transdermal variants

Some users note a burning sensation during urination, which is a rare and generally harmless side effect.

Compared to boldenone, dihydroboldenone cypionate puts less strain on the hematocrit while delivering greater strength gains. This matches the potency profile of Primobolan at a higher level.
