1-TU is new to the market, no serious lifters that I have come across have used it.
If you want to compare products and get an idea what it might do then read about 1-AD. I've talked to a group of serious lifters and there were some questions raised about 1-TU. We're not sure how they can make such large claims yet every serious lifter on any forums doesn't know much about the stuff.
If you read about any Nutrex product they really hype it. Keep in mind it's not a US based company and the sources are Europeon so they might not be on the up and up. It seems the price is fixed at about $53.95 online which suggests to me it's the lowest price the manufacturer will allow it to be sold. Consider that and all the hype, I'd bet it's marked up a lot and they want to push it to turn a dime.
However, it has to do something because nobody would want to push bad gear.
I would guess 1-TU is going to increase DHT (can cause hair loss in high amounts, but unlikely on a pro-hormone), cause oily skin, acne, an increase in appetite, and maybe cause you to be irritable.
But like I said, read about 1-AD, the stuff is the bench mark.
Steve has a good point. Your age. I wouldn't recommend a pro-homorone if you're not in your 20's. You're natural test production is pretty high if you're in your teens and it starts to drop off in your mid to late 20's.
Steve also quoted the manufacturers information, which I take with a grain of salt until we see some results. If you look up 1-AD you'll also find hundreds of people who used it and had results. 6-9lb gains in 4-6 weeks.
If you're younger than I suggest holding off on that product. Take pure creatine, and find some good Whey protein like Optimum. If you want to spend a little more on some better protein go with an isolate. If you want some good Creatine Nutrex Vitargo-CGL is cheaper than EAS PhosphagenHP and doesn't cause
insulin spikes.
Eat 2 - 2.5 grams of protein per pound of body weight and get 8 hours of sleep. That's the most important thing you can do. If you want to try a good workout that hasn't caught on yet and gives impressive results try the HST workout. Look it up on the net, it's a great work out.
Again, if you haven't been lifting for a few years, skip the pro-hormones, get some creatine and stick to the basics. The basics always work, that's why they are there.
And if you do decide to take 1-TU, pick up 4 bottles of 6-OXO. It's an estrogen supressor. After you cycle 1-TU for 6 weeks or so your bodies natural test production will practically not exist. So you will need to keep your
estrogen levels in check for 4 weeks while your body begins to make it's own test again. If you don't then you have a slight chance of developing Gyno, aka Breasts.
Hope this helps...
