letro help

hey guys so currently I hopped onto letro because the arimidex on 420mg a week of test cyp didn't cut it and I developed a bit of gyno but it looks like ive zapped it with four days at 2.5mg. I have aromasin and arimidex and I want off letro asap because I need moist joints for my lifts. any...

I really would prefer pharm grade Letro, but can you guys please share which Letro sources you've had the most success with?
