Description

Dihydroboldenone Cypionate (ZPHC) / 1-Testosterone Cypionate

Dihydroboldenone Cypionate, also known as 1-testosterone cypionate, is an injectable anabolic steroid derived from boldenone. It is structurally modified by the removal of the double bond between the 1st and 2nd carbon atoms, resulting in a compound with strong anabolic properties and relatively lower androgenic activity.

General Overview

Dihydroboldenone cypionate is the long-ester (cypionate) form of 1-testosterone, designed to provide a slow and sustained release after injection. It is primarily associated with lean muscle development, strength improvement, and enhanced physical conditioning without significant water retention.

Pharmacological Profile

Anabolic activity: Very high, estimated around twice that of testosterone
Androgenic activity: Moderate, approximately 50% of testosterone
Estrogenic activity: None, does not aromatize
Hepatotoxicity: Low (injectable, non-17α-alkylated)
Half-life: Approximately 7–8 days (due to cypionate ester)
Progestogenic activity: Low

Noted Effects

Significant increase in lean muscle mass
Improved muscle density and hardness
Increased strength and training performance
Enhanced endurance and recovery capacity
No water retention due to lack of estrogen conversion
More defined and dry physique appearance

General Characteristics

Provides steady, long-lasting anabolic activity
Produces dense, quality muscle gains rather than rapid bulk
Often associated with improved conditioning and muscle definition
Requires time for full effects due to slow ester release

 Side Effects

Suppression of natural testosterone production
Androgenic effects such as acne, oily skin, and hair loss in genetically sensitive individuals
Potential cardiovascular strain with prolonged use
Possible increase in blood pressure depending on dosage and individual response
No estrogen-related side effects such as gynecomastia or water retention
