Legal Anabolic Steroids

Just an update: most prohormones are illegal in UK. There is a list of 24 most common substances considered as testosterone precursors which are illegal. But with some "designer prohormones" you may slip in between, though.

It is highly unlikely that the UK customs will not seize any prohormone thay find in your luggage/parcel, bro!

They will seize even the legal stuff, not just prohormones, anything they think might resembe gear they seize and then possibly ask you for explanation (not neccessarily).
