If it is hard for you to put on weight or you generally don’t eat alot of food before you get full I wouldn’t recommend taking Tren. The only change I’ve noticed and I’m about halfway through my cycle is that my muscle expenditure is greater which means my muscles just don’t get tired as fast and my pumps are quite bigger than normal or more than they have been in the past. I’ve only put on about a solid 3lbs of muscle tho but one last thing I will say is if your body type is anything like mine don’t take this. Just start eating and gaining weight that way then when you get to a size you want to keep then buy Tren and start working out and taking it you’ll notice greater and faster results cause Tren is used for cutting and maintaining a weight not so much for bulking. Overall the product does work just not for the purpose I had envisioned (bulking). I recommend this product it is quality
