Cabergoline (Dostinex) interactions
with Trenbolone
Caution · moderateTren raises prolactin; cabergoline reins it in. Watch for excessive prolactin suppression (low libido, mood) at higher cab doses.
Timing: Cabergoline 0.25–0.5mg 2×/week alongside Tren cycles
with Deca-Durabolin
Compatible19-nor compounds elevate prolactin; cabergoline mitigates the libido/erection issues commonly reported on Deca.
Timing: Cabergoline 0.25mg 2×/week during nandrolone cycle
with Nandrolone
Compatible · lowNandrolone raises prolactin via progesterone receptor activity. Cabergoline (a dopamine agonist) controls prolactin-related side effects including sexual dysfunction and gyno.
Timing: Start cabergoline 0.25mg 2×/week when running nandrolone above 300mg/week
with Trenbolone
CompatibleProphylactic cabergoline controls tren-induced prolactin elevation, mitigating libido and mood side effects.
Timing: Cabergoline 0.25mg 2×/week during tren cycle
