Boldenone Undecylenate
Also known as: EQ, Equipoise, Bold Undec
Boldenone Undecylenate, commonly known as Equipoise (EQ), is a veterinary-grade anabolic steroid originally developed for use in horses. It provides slow, steady lean mass gains with modest androgenic activity. It is valued for increasing appetite, vascularity, and red blood cell production.

Mechanism of Action
Boldenone is a structurally altered form of testosterone with a double bond between carbons 1 and 2, reducing its estrogenic and androgenic activity. It aromatizes at approximately 50% the rate of testosterone. The undecylenate ester gives it a very long half-life of approximately 14 days. Notably increases erythropoietin (EPO) production.
Dosing Research
Performance enhancement dosing typically ranges from 300-800 mg per week, injected once or twice weekly. Due to the long-acting ester, cycles are typically 12-20 weeks to realize full effects. It takes 4-6 weeks for blood levels to stabilize. Often stacked with testosterone.
Side Effects & Risks
Significantly increases red blood cell count and hematocrit, which can increase blood viscosity and cardiovascular risk. Moderate estrogenic effects. Can cause anxiety in some users. Androgenic side effects are moderate. Suppresses natural testosterone production. Can produce metabolites detectable for up to 18 months in drug tests.

Testosterone Enanthate
SteroidTestosterone Enanthate is one of the most widely used testosterone esters for hormone replacement therapy and performance enhancement. It features a long-acting enanthate ester that provides sustained release over approximately 1-2 weeks, making it one of the most convenient injectable testosterone formulations.
Testosterone Cypionate
SteroidTestosterone Cypionate is a long-acting testosterone ester very similar in pharmacokinetics to Testosterone Enanthate. It is the most commonly prescribed form of testosterone in the United States for hormone replacement therapy and is widely used in performance enhancement contexts.
Testosterone Propionate
SteroidTestosterone Propionate is a short-acting testosterone ester that requires more frequent injections than longer-estered variants. It provides faster onset and clearance, making it preferred for shorter cycles, contest preparation, or situations where rapid clearance is desired.
Oxandrolone
SteroidOxandrolone (Anavar) is one of the mildest and most well-studied oral anabolic steroids. Originally developed for medical use in burn patients, muscle wasting, and osteoporosis, it is valued in performance enhancement for producing lean, dry gains with minimal side effects. It is one of the few steroids prescribed to women and children in clinical settings.
