Ive been curious as hell to try letro simply to find out if it really does help reduce some pre-existing gyno since im super sensitive to even low ass doses of test, it effin sucks sucks!! let me know how this ends up working for you please I've been using Adex straight from cvs pharmacy since i found out my dad had literally 5-6 bottles (including the ridiculously expensive Astra zeneca brand) so i talked him into given em to me although im def gonna order me some aromasin and possibly the letro to see what works best when i do my next cycle.
