This is just my 2cents... If you don't have anything laid out or don't know where to begin, I'm sure that's not exactly what you meant... Prob just meant you're excited to start pinning? I would generally say run all short esters together, but would prob change that just slightly if this is your entire stash for this cycle. 1-hold the EQ for next cycle you have one vial and IMHO just not worth even starting it unless you have a decent cycle. But again if this is your entire cycle I would start with your short esters almost as if you were going to front load but you have 2 vials of test p, and tren a, then one of what looks like mast p?
I would pin the test p and tren a together to start the cycle eod (I'm not even going to get into concentrations) run those till they're gone, then switch to your longer ester of the two that you have the test e and introduce that a day b4 your last test p inject. Run the first test e vial "alone" or calculate your dosing to split the tren e equally amongst your two test e vials... But again "I" would run the first vial alone, then pair your last vials together test e & tren e.... Then introducing the mast p at the end of cycle to shed that last bit of water weight and harden up.

Again this is just how I would run it... And not suggesting you necessarily do so... Do a lot of research!! there are several forums on here discussing similar cycle to this.

Also, I assume that HCG isn't the extend of your pct? What are your plans there, and do you have an AI and caber or prami on hand for the tren?

Good luck bud

What do you mean you don't know which to start first? You ain't got a cycle laid out? You're fucking up "brah".
