Core Effects

Testosterone 1-Cypionate (DHB) is a potent anabolic steroid widely used in muscle-building cycles, strength development, and performance optimization due to its high anabolic activity and low estrogenic properties .

✅ Powerful muscle growth :

Promote protein synthesis , and increase muscle mass by 8-12kg in 10-12 weeks

Significantly improves muscle firmness and definition

✅ Strength burst enhancement :

Improve muscle strength and explosive power , break through training bottlenecks

Increase muscle density and improve muscle quality

✅ Low estrogen properties :

Does not aromatize into estrogen , eliminating the risk of estrogenic milk and water retention

Does not convert to DHT , no risk of hair loss and benign prostatic hyperplasia

✅ Advantages :

Long-acting esterification , half-life of 10-12 days, stable blood concentration

The injection frequency is low , 1-2 times a week is enough to maintain the effect

End Product Preparation Guidelines

1. Preparation of injection oil (100mg/ml) :

Recipe example (preparation volume for 100ml):

1-Testosterone Cypionate Raw Material: 10.0g

Benzyl alcohol: 2.0ml

Cottonseed oil: add to 100ml

Preparation process :

Raw material pretreatment : micronization (D90≤10μm)

Dissolution and mixing : Heat in a 40°C water bath and stir magnetically until completely dissolved

Sterile filtration : 0.22μm membrane positive pressure filtration

Subpackaging : Subpackaging into sterile injection bottles under aseptic environment

Quality Control :

HPLC assay : 95-105% labeled amount (95-105 mg/ml)

Endotoxin detection : <0.5EU/ml

Sterility test : 14 days of incubation by membrane filtration

2. Preparation Notes :

Dissolution Optimization :

Heating temperature : 40-45°C is best to avoid high temperature degradation

Stirring speed : 200-300 rpm to ensure complete dissolution

Solvent Selection :

Cottonseed oil : most commonly used, good stability

Sesame oil : Low allergy risk
