Tren is one of those compounds where more isn’t always better, especially once you start pushing the dose. The fact that you’re not getting major side effects at 25 mg doesn’t necessarily mean 50–100 mg will be smooth — sides can increase very fast and sometimes with a delay.
Also, not everyone blows up in strength or size on Tren. A lot of the “PR stories” you see online are from people running higher doses, longer cycles, or stacking aggressively — often at the cost of health.
If results feel underwhelming at week 4, it’s worth looking at training intensity, recovery, sleep, food intake, and expectations before increasing the dose. Sometimes the gains are more subtle (hardness, recomposition) rather than dramatic scale weight or max lifts.
Personally, I’d be cautious about doubling or quadrupling the dose just for the last 2 weeks. That’s usually when side effects show up but benefits are limited. If you decide to push it, keep the increase modest and monitor yourself closely — or consider finishing the cycle clean and reassessing next time.
Tren is powerful, but it’s also unforgiving.
