4-DHEA is a naturally occurring non-methylated (non-17aa) pro-steroid.
4-DHEA, like DHEA, requires a 2 step conversion process involving 3b-HSD and 17b-HSD to convert it to Androstenedione/androstenediol, and then 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 is probably not enough to cause high estrogen related side-effects.
Overall results will be similar to or the original 4-AD banned back in 2004. Higher doses of this compound will produce fairly lean gains in muscle mass, with moderate improvements in strength. This product may produce some bloat from the estrogen conversion, which could be countered by administering an aromatase inhibitor, but this will largely defeat the purpose of using this compound to begin with.
Since this compound is naturally occurring and non-methylated overall side-effects will be fairly mild. However, high doses may also lead to oily skin, acne and increased blood pressure. Because this steroid is non-17aa there should be less concern about it negatively affecting the HDL/LDL ratio.
Because this compound can convert to testosterone it can also convert to DHT and other 5a-reduced metabolites. This can serve as a good stack with progestational or relatively non-androgenic compounds that may create problems with libido or gyno because of lacking androgenic potency.
Although this compound is relatively safe and moderately effective, its high cost has probably been the reason for its lack of popularity.
