I highly discourage running Mast E and Tren E.
The shorter esters of this compound is better in every way.
The better MastE alternative is Mast Prop or just simply high Testosterone. MastE isn’t worth running – anyone who knows their compounds would agree greatly with me.
Tren you shouldn’t have that in your body for a long period of time and the extended half life of the E ester, doesn’t help either. The acetate version is better and has less side effects. Please consider that one.
It’s not that there is anything wrong with the compound and the way it is made, but I’m telling you how it is and what is worth running.
If it’s for resell, it doesn’t matter and you can ignore this message.
If it’s for personal use, please consider what I’m saying.
To clarify, there is nothing wrong with the vial, I’m telling you the same thing which I tell my IFBB competitors with the advice above.
