Ive been meaning to do this for some time now, so here goes my limited advice from a mature (48 YO!) long term lifter who decided after all these years to take the big AAS plunge:
DO's:
Research, research, research then research some more.
Listen to what EXPERIENCED users tell you like on MG it will help.
Find a good source, for first cycle you want the real deal (use MG Source section).
Always use Testosterone as a base on all cycles and on your first just on its own.
Start off on a manageable dose, 500mg PW of Test E is a good starting point.
Really research and watch YouTube vids on how and where to PIN.
Find a good source for syringes & needles, make sure they are sterile, etc.
Clean and sterile PIN site, use alcohol swabs before and after and on the top of the bottle.
Try to overcome your fear of needles and self injecting, oral only cycles are not the way.
Have Ai on hand and purchase your PCT WITH your Test.
Try and ejaculate every day, either self or sex just to keep the little fellas going.
Try an get blood tests done before during and after, in the UK this is not cheap.
Work out hard, eat clean, do cardio and enjoy!
DON'T's:
Expect AAS to be a wonder drug, you need to work out regularly and eat well.
Ignore the risks with Steroid abuse, Pro BB are that size for a reason & have good Doc's to help.
Think Steroids are cheap, they are not. A 12 week 500mg Test E cycle with Ai, PCT, Var is £200.
Just do Oral's only, you need to inject and you need to use Test E/C, etc.
Think you will become Arnold after one cycle, trust me you won't.
Become that gym Roid arsehole, that you have always thought 'what a tosser',
Disrespect other ironmongers, we all want the same thing so keep the ego at the gym entrance.
Try and squat 320lbs after 4 weeks in, trust me it won't end well!
Ever give up halfway in, it gets tough, injuries, family commitments, work, etc but keep on going.
Ever, ever, ever, ever ignore advice from Dolf, Sieg, Strong and some other top members on here for which the list is too long to thank for my amazing journey.
Well thats it from a newbie, after 48 years I now believe I am mature enough to assess the pro's and con's of steroid use, I don't intend abusing AAS's but intend to continue using and respecting what they can do for someone my age.
Thanks.
