You can try starting with the Mix 2, and see how you do.
Most of the Mix Lines from Pharmacom have Ethyl Oleate in them, to make them thinner.
While also making them able to hold Higher Mg.
Some people are Very Sensitive to EO.
This is why I recommend sticking with the Larger Muscles, until you assess if you are one of those people.
EO can sometimes Lump-up under the Skin.
Usually the Higher the Concentration, the more the EO, the more sides.
But you may be OK with the Mix 2, as it's a Medium Concentration.
Test Phenylpropionate has around a 4.5 Day Half-Life.
So it shouldn't Bloat you as bad as a Test C or E.
If you decide to do the Mix-2 from the start.
Make sure to start your Aromasin and Caber from Day 1.
Then keep a Daily Journal of how you are feeling, and if you are noticing anything.
This will help Zero-in on the Correct Dosage of Aromasin...................................... JP
