if you cannot handle the tren then lower the dose.
i have ZERO mental problems on tren running 100 EOD and now 125 EOD.
best thing is to run tren ace.. if you cannot handle it then just stop or lower the dose.. its a short esther and will be gone quick anyway. so play it by ear.
as for your question nothing compares to tren.. it works fast and it builds ridiculous strength and mass QUICKLY which is NOT water weight. thats why nothing compares to it IMO.
you can stack mast/primo/oral and get something close i suppose, but you wont get the fast results
