No different really. Maybe testp a bit more acne. Get gyno, bit of bloat from both but just take anti-e and its fine. I dont even bother with testp anymore, only enanthate regardless if I am trying to add or lose. One thing I have noticed is that the side effects (water retention and gyno) are no different from 250mg to 500mg test yet the gains I see on 500mg as apposed to 250mg are two fold. Only if i drop down to 125mg of test a week do i not get any sides. When I am on 250mg a week I can maintain my strength and size but dont look all that great yet still have a puffy face and gyno if i dont use an anti-e however if i bump up to 500mg (keep in mind no other compounds) I look twice as good, more vascular, pumped and hard but no extra sides. Cant go over 500mg though or I have to use too much anti-e and skin gets too dry from this. 500mg test and 600 eq a week is my blast these days. Haven't tried tren yet but possibly this summer i will give it a go just scared of getting acne. Holding water has never been a big issue for me, only gyno. I think it has a lot to do with structure also which is just common sense really. Taller, bigger built guys with broad shoulders seem to be able to smash test and not look like a bloated whale but anyone under 6foot should stick to moderate test and high anabolics. Sounds dumb but just what I have noticed.
