1,4 Andro = 1,4-Androstadienedione
1,4 Bold = 1,4-Androstadiene-3,17-dione
Boldenone (equipoise) = 1,4-Androstadiene-3-one, 17b-ol
1,4 andro is a matrix of several isomers
1,4 Bold, a direct precursor of Boldenone, has ketone substituents on the same carbons as the ketone and alcohol substituents of Boldenone. Because of it is solely the direct precursor, it has a much greater coversion rate, and would be more powerful than
1,4 Andro.
1,4 AD was one of the PH's that made it throught the ban loophole of 2004, but was considered such a gray area, and was dropped by many supplement companies for liability purposes. Because new legislation has not taken effect to ban 1,4 AD isomers, Iforce can market it, but takes a risk in doing so. Not to say it's anymore risky to market
superdrol.
Boldenone is an illegal steroid with a long half-life, often used to beef up race horses. Because of it's half-life, successful boldenone cycles are longer cycles (over 4 weeks) because it takes a while for metabolites to build up and take effect.
Though
1,4 andro and 1,4 Bold aren't as powerful as such
prohormones as
Superdrol or
Pheraplex, they have been thought to provide gains that are more easily maintained.
In closing, 1,4 Bold is not the same as
1,4 Andro. It takes a longer cycle to
see results (so you're going to need 2 bottles to get the job done). It's not as powerful as less expensive
prohormones (this one is going to cost you over $100, and that excludes
PCT and/or cholest/liver support). It's probably not worth your money at this price.
Also,
Molecular Nutrition (creators of the covetted
X-factor) used to make a PH, called
Boldione, which was the same compound before they jumped off the PH bandwagon.
