The main thing is to get REAL Product. USA FDA inspected stuff is #1.
Organon or Schering from our Friends in Iran and Paki is also unfortunately legit testo.
The Greeks stuff also. India, S. America....
Skip sachets; and all dog & Pony shit from Mex, and of course skip your local UG kitchen/bathroom bacteria cocktails.
They simply contain way more strains of bacteria than Organon ever intended esters of testosteron in Sustanon. Remember you blood flows thru your veins, heart, brain,,,
TE shot 2x ew will give the smoothest ride for most beginners IMO.
The TD in Sus makes for a very long clearance time after several weeks of use.
Many guys are really never off when they start up next cycle again when SUS was in the previous.
They think they were off, but they were not.
Making sure its high quality and using less should be the goal instead of Hero dose of trash.
Many guys would find they need WAY LESS than they use if they got into real stuff.
