Long cycle, estrogenic compounds present, especially meylated estrogens, deca...
No one is commenting because this is 100% to be expected.
Deca lingers in its surpression, and chemically lingers as well for a completely unacceptable amount of time. No one uses deca anymore, its what they used before they had better options.
In terms of pure muscle tissue growth, deca is simply not the strongest drug available. Combine that with prolactin sides while on, as is likely part of your case here, and you simply have a recipe for suppression.
Its nice to see some HPTA recovery, I would add an AI in not an SERM, and drop the SERM completely. You may need to address prolactin now if you did not have prolactin support on cycle, it is impossible to tell, but if you had prolactin support on cycle you will simply continue dosages but lower, if you did not then you will need to research prolactin and deca.
