Similar to 1-Andro, 4-Andro is a DHEA metabolite, a naturally occurring non-methylated (non-17aa) pro-steroid.

4-DHEA, requires 2 steps to convert to Androstenedione/androstenediol, and from there to testosterone. What makes 4-DHEA slightly different from DHEA is a double bond in the 4th position rather than the 5th. This makes 4-DHEA less estrogenic by not acting directly upon the estrogen receptor like DHEA has been found to do.

Although 4-DHEA can aromatize to estrogen, it's very limited and probably not enough to cause high estrogen related sides.

Higher doses can produce fairly lean gains in muscle mass, with moderate improvements in strength. There may be a bit of bloat from estrogen, but this is not typical. Any estrogenic sides could be countered by an aromatase inhibitor, but this can limit overall gains and is not recommended except in extreme cases.

A non-methy, so overall sides are typically mild. High doses have been know to cause oily skin and increased blood pressure. This compound can convert to DHT and other 5a-reduced metabolites. Although relatively safe and moderately effective, it tends to be expensive.

A good compound to stack with.

4 androstene-3b-ol, 17-one


4-DHEA may appear under the nomenclature 4-androstene-3b-ol, 17-one.

4 androstene 3b-ol, 17-one is a prohormone to 4-androstenediol. And 4-androstenediol is a prohormone to testosterone.

4-DHEA does not have much anabolic activity on its own, but it converts to testosterone in a two-step process involving the enzymes 3bHSD and 17bHSD. 4-DHEA first converts to androstenediol and androstenedione and then to testosterone.

In 2004 several prohormones and steroids in food supplements were forbidden by the American government. Among them were the prohormones of testosterone. However, in the Anabolic Steroids Control Act almost no steroids with a C17 carbonyl group are mentioned. Supplement producers gratefully use this omission, and have marketed 4-androstene-3b-ol-17-one as a testosterone precursor.

Two step pro hormone. stares out as 4-dhea, must be converted to either 4-androstenedione, or 4-androstenediol, and then must convert into testosterone. Alot of chances for it to not make it to test.

It will likely convert rapidly and extensively to androstenedione. Androstenedione can convert somewhat to testosterone but it also aromatizes easily. It may (and this is quite theoretical though based on some fact) convert to testosterone better than androstenedione itself though. And that is because the first conversion can increase NADPH/NADP ratio in liver, and that will help the efficiency of the second conversion.

Eh.... seems to be a lot of conflicting info here. Do your research!

Hydroxypropyl Beta Cyclodextrin

Cyclodextrins are a family of compounds made up of sugar molecules bound together in a ring. Cyclodextrins are produced from starch by means of enzymatic conversion. They are used in food, pharmaceutical, drug delivery, and chemical industries, as well as agriculture and environmental engineering. Hydroxypropyl Beta Cyclodextrin is the chief active compound found in Procter and Gamble's deodorizing product "Febreze" under the brand name "Clenzaire".

Hydroxypropyl Beta Cyclodextrin is a prime candidate of all the chemically modified Cyclodextrins for incorporation into formulations used by humans and animals. HPBCD has the best balance of enhanced aqueous solubility, a wide range of drugs with which it forms stable complexes, and the most extensive collection of safety data in the technical literature with no adverse reactions reported. HPBCD is itself very soluble in water.

Basically used in solution to facilitate drug delivery.
