Primo, definatly primo.
1stly, you don’t need an anti-e if you’re using, say 300mg test, tren and primo. If you added 300mg eq instead of primo, you’d probably need some nolva kicking around. So you don’t need to pay for nolva, and maybe primo would seem more economical given this consideration.
2ndly, water retention would be lower with the primo.
3rdly, EQ increases RBC count, sometimes to unfavourably high levels. Primo doesn’t ahve this problem
4thly, reiterating what PDOG said, the appetite stimulation on the EQ could be very annoying when on a low-cal cutting cycle.
5thly Primo’s easier on the hairline than EQ…
6thly expanding on point one, the eq’s aromatization to estrogen is also detrimental to fat loss. As stated in point 2, the E2 also causes water retention, leaving you look less cut (and heavier).
7th recovery will be compromised more with the EQ due to it’s long lasting ester and the suppressive nature of this androgen. With primo, you’ll be recovering a lot faster…
Primo’s good for your joints just like EQ, and will provide a solid anabolic base. Combined with tren and test you’ll get good strength gains and minimal sides.
A stack of 300mg test, 350mg tren, and 300-600mg Primo would be prime for fat loss, have no 17-AAs to strain your liver (regardless of whether 17-AA toxicity is overrated), would have low sides, and would be kind to your joints. All you’d need is some nolva (&maybe clomid) for PCT.
Scorp: are you planning on any stims (clen, E+C, yohimbine) or other fat loss aids (T3, GH, etc.)?
I’m actually considering this exact cycle for summertime (maybe with the clen and T3) !
