At 4 weeks of the same weekly dose of enanthate esters, your blood plasma levels of the compounds should be peaking around now-next week.
Night sweatiness is a side of Tren. Ideally, if you are lucky, you won’t see much more sides.
If you aren’t seeing a bit more pumps, or any weight gain (or loss), another rep here or there, or adding a little weight on some exercises, something soon, then I would question the gear before long. But the sweating at night is a great sign, and you’re probably just not very observant or expecting too much too soon (no disrespect intended, just speaking bluntly).
