Nomenclature:

2a,3a-epithio-17a-methyl-5a-androstan-17b-ol or 2a,3a-epithio-17a-methyl-etioallocholan-17b-ol

Anabolic/Androgenic Ratio:

1100:91 vs. methyl test by oral administration [1]

Synonyms:

Epistane, Havoc, Epi, E-Stane, Epi-Strong, Methylepithiostanol

Etymology:

Methylepithiostanol: Methyl indicates the 17a-methyl group, epi means above, indicating the bridge, thio indicating sulphur, stan is short for the androstane skeleton, and ol points out the hydroxyl at 17b.

History:

One of a number of steroidal compounds researched in the 60s by Searle Laboratories, while it was never used clinically in the West, the unmethylated analog epitiostanol has been used to treat breast cancer and gynecomastia in Japan. [2][3]

The two first "prohormone" products containing this compound, IBE's Epistane and RPN's Havoc, are still the two best-selling "epi" products on the market.

Structure and Function:

Resembling methyl DHT, but with a sulphur atom spanning C2 and C3, methylepitiostanol is an orally active compound that lacks the 3-ketone common to most anabolic steroids. Some of it's activity will be due to metabolism in vivo to other active compounds - including desoxymethyltestosterone (pheraplex). [4]
It will undergo dethionylation (loss of the sulphur atom) both in vivo or via pyrolysis (administration of high temperatures) to produce phera, as illustrated in this diagram. [5]

Effects:

Greatly increased protein synthesis and accrual of lean muscle mass with attendant strength gains. Some fat loss may be experienced, though this is dependent on diet and training.

Side Effects:

Side-effects may include (but are not limited to): loss of or heightened libido, elevated liver enzymes and potential temporary liver function impairment, HPTA disruption, adverse shifts in lipoprotein subfractions (lowered HDL, increased LDL cholesterol), acne, hair growth or loss, and an increase in blood pressure. This product should not be used by women or teens.

Gains are very lean and dry with many users complaining of sore joints (so a joint supp like Joint Force would be recommended to those experiencing pain or discomfort).

Recommended Dosages and Cycle Durations:

Cycles are typically 30 - 40mg daily for four to six weeks, followed by a SERM PCT protocol to avoid "rebound gyno".
