theyre both good, but i think 6-bromo might increase your stregth more.
Formestane is good because i dont know how i place it against 6-bromo
Combo formestane might be fun to run. Hyperdrol before work out, form at night, for instance.
Both are said to possibly convert into weak steriods in weak dosages.
Overall, id say formestane by small margin for right now, but i tryed hyperdrol a long time ago, so id have to try it again, especially hyperdrol x2 which has forsklin which irratates my stomach.
Formex should be good, but suppodly transdermal form by cel should be have a better price-to-ratio.
As for PCT, i dont know which one would be better.
