1,4-androstadiene-3,17-Dione (androst-1,4-diene-3b,17b-dione) is the ingredient contained in the Boldione (Bold / Boldenone) prohormones. This prohormone is a good rate of conversion into the steroid know as "boldenone" or "Equipoise". We can call it Bold, Boldione or Boldenone prohormone. Boldione prohormones uses two nomenclatures so here a list of all the names known you could see for these prohormones : ● 1,4-androstadiene-3,17-Dione ● 1,4-androstadiene-3b,17b-dione (more official for chemistry) ● androst-1,4-diene-3b,17b-dione 1,4-androstadiene-3,17-Dione is often considered like a "weak" prohormone because results (gains) only start to kick in after about 4 weeks of taking it. However, Boldione prohormones are quite good for bulking cycles. Strength and muscle gains are steady and quite important if you do a full prohormone cycle of 8 weeks. Also, 1,4-androstadiene-3,17-Dione is non methylated (no liver support is needed) so you can stack your boldione prohormone with an other prohormone. Dosage recommended for 1,4-androstadiene-3,17-Dione (androst-1,4-diene-3b,17b-dione) is at least 600 mg daily for a 6 weeks cycle. However we recommend to go with a 600-800 mg daily dosage for 8 weeks cycle to get maximal gains in muscle and strength. Some experienced users even take up the dosage of Boldione at 1000-1200 mg but at this point, it's quite high !
