In libido
I also read a lot on various forums that AIs can increase estrogen receptor sensitivity making you more likely to get gyno if you ever stop taking them but have never been able to find a reliable source on this
Overall I am of the opinion that testosterone is a shitty steroid which isn't every anabolic but has a load of side effects and that people will get better results low dosing the testosterone and upping the dose of other compounds like deca or equi. EG instead of 500mg test a week, 200mg test + 300 equi (or deca, tren whatever) would yield much better results. People should just run the hormones that give the best results with the lowest side effects and this varies from person to person and for many people (as demonstrated yourself) testosterone is a drug that just isn't worth the side effects
I have read about estro rebound, but dont know enough on the topic to elaborate.
Christian would be the man to talk to, but he rarely posts here anymore.
My libido is fine, its always been high.
I also agree on the point about low test, with higher dosages on other compounds.
What you need to realise is though, this forum is very much a noob forum when it comes to gear. Guys want to run an oral only cycle, or get their toes wet with their first test cycle, which is the best way to get started.
The best information IMO to provide is the basic information for them to carry out their cycles as easily and safely as possible, keeping in mind they wont have access to many compounds, even if what they are getting is any more than olive oil.
What Im trying to say is we should cover the basics and cover them well.
Whilst mast is very good for lowering e2 when on cycle, IMO, its useless for a beginner.
