no, if Adex isn't working letro probably wont either. What you need to do is start B6 @ 500mg/day. Continue @ 2-300mg/day to prevent gyno flare ups. If this doesn't do the trick you will need Caber or Bromo. Adex and letro fight estrogen.
Tren is prolactin gyno, different then estrogen gyno. And altough sometimes excess prolactin is caused by excess estrogen, this isn't always the case.This is exactly why i recommend running an Aromatase inhibitor (AI) when using tren/deca (like u are) as its reduces the chance of both types of gyno, but if it persists you can be confident that it is prolactin induced.
