I agree to an extent with this sentiment, I believe at the AR is overexpressed until a system wide shutdown occurs which may explain why people experience a crash, high estro manifesting in gyco, etc. Cartinine allows for better utilization of new T (whether it be training induced or through various sources) via NEW AR production (see studies below). Another indicator that ex-fin users experience depleted AR as opposed to over expressed AR is that the symptoms commonly we commonly discuss are associated with low AR. A study surrounding androgen deprivation therapy for prostate cancer patients and it’s effects on males sited ED, muscle wastage and loss in muscle function, compromised metabolic function, bone mass resulting in obese frailty as first hand side effects. I don’t buy that our AR is permanently over expressed, because if that’s the case your Free-T would be extremely low and DHT would be high which isn’t what we’ve seen on blood panels posted on this forum.
Another thing to note is that the form of Cartinine I take (l-cartinine tartrate) is metobilized in the muscle, not blood-brain barrier. So unless you are actively stimulating new T development through working out, this probably won’t work for you.
