Typically just by talking and getting to know someone that's in a gym working out that may know where to get a hold of it or uses it himself.
Probably not something you would just come out and ask all of a sudden but possibly mentioning it to whoever you end up speaking with a little later.
I have had a friend do this same thing when he started doing steroids and I do not recommend ever using them if you are planning to start doing that.
Check this out.
Comparing my friend and my girlfriends brother.
My friend
age 26
height 6 feet
Used steroids
He did not lift much but had gained muscle fast. Now he is flabby from not lifting anymore and this is from approximately a year.
The Brother
age 18
Height almost 6 feet
No steroids
Stopped lifting over a year ago and still has bulk muscle and is really big still.
He was benching around 300lbs in sets of 4 lifting 8-10 times with about 4-5 minute breaks each time.
He has not lost anything and gets to make fun of my friend that is a little girl for putting no effort in working out to get his muscle.
You would laugh if you knew who this friend is as he has been on MTV before, hahaha.
From what I have read it is mainly thru knowing someone who knows someone that can get them or thru ordering them from the internet or an ad in the back of a fitness mag.(using a term which does not use the word steroid).It is a risky thing to do either way.Many get ripped off thru the mail or get something which may be something other than what is ordered,such as a dangerous mix of ingredients that a body may be allergic to or which may be toxic to the kidneys or liver.Talk to your doctor and ask for info. because there are many horror stories of guys who had severe reactions/side effects or became deathly ill from doing what they thought was legitimate and alright to do but was the oppisite.
People can either get steroids from prescriptions [it can make the body temporarily stronger to fight diseases] or underground [illegally]. The source is inevitably some corrupt pharmacist who sells it or almost always some sick individual with a prescription [legal] who sells it [illegal].
In a gym once i was looking at some protein mix body building magazines and some old guy with really elastic skin who was always at the gym came to me and told me; ''hey i got that one, and that one, and if you want i can get you some other stuff....''. His reference of ''some other stuff'' was probably steroids.
Most dealers are at community colleges, where athletes have a last chance to get a scholarship to make it in college sports to be seen and known.
I believe most steroids are actually legal and you can order them.
I want to know how?
