Epistane
Also known as: Methylepitiostanol, Epi, Havoc, 2a,3a-epithio-17a-methyl-etioallocholan-17b-ol
Epistane (Methylepitiostanol) is a methylated designer steroid derived from epitiostanol, a compound that was used in Japan as an anti-estrogen breast cancer treatment. It is known for producing dry, lean gains with mild anti-estrogenic effects. It was one of the more popular designer steroids before being banned.

Mechanism of Action
A 17-alpha-methylated derivative of epitiostanol with an epithio (sulfur bridge) group. Binds to androgen receptors directly and also has anti-estrogenic properties through binding to estrogen receptors without activating them. Does not aromatize. Does not have progestogenic activity. Promotes lean, dry gains without water retention.
Dosing Research
Typically dosed at 20-40 mg per day in oral form. Cycles of 4-6 weeks. Often used in cutting or recomposition phases due to its dry, lean effects. Liver support required due to methylation. PCT is necessary. Sometimes stacked with a wet compound for balanced results.
Side Effects & Risks
Hepatotoxicity from 17-alpha-methylation, though considered moderate. Joint dryness similar to stanozolol due to anti-estrogenic and drying effects. Negative lipid profile changes. HPTA suppression. Androgenic side effects including hair loss in predisposed individuals. Lethargy at higher doses. Back pumps commonly reported.

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.
