Hi Tech Pharmaceuticals 1-Testosterone is one of the most effective prohormones ever produced in the supplement industry! This highly anabolic prohormone will help you receive a pure and lean bulk with its formula of potent 1-Androsterone and Bergamottin. 1-testosterone has been tested in a university study to prove that men gained lean muscle mass. In fact, these men gained about 10.4 lbs of lean mass on average! 

The main components of Hi Tech Pharmaceuticals 1-Testosterone, 1-Androsterone and Bergamottin, are effective and potent for you to achieve a pure, clean, and lean muscle bulk. This product also helps preserve and increase your muscle definition on top of bulking up. 1-Androsterone is a very effective derivative of DHEA, that is more effective and more anabolic than testosterone, with no conversion to estrogen either. Bergamottin is naturally found in grapefruit and works as a pair with the 1-Androsterone to make it more effective and able to pass through your system. This effective formula makes Hi Tech Pharmaceuticals 1-Testosterone one of the most effective prohormones on the market.

No other choice

I use this item all the time, the issue is I wanted to try another item the dianabol which was in stock when I ordered it only to get a call a week later saying it wasn’t. So I had to order the test 1 instead.

Best Andro's in the market!

This is my second time using the 1-Andro product from Hi-Tech and I love the results. Within the first two weeks, I can see abs, quads, shoulders and biceps coming out and the skin feeling tighter. It will give you a slight burning sensation as a fever, and the body will feel warm all over.

Replacement bottle

I received a bottle, and the inner seal was broken. Supplement warehouse sent me out a replacement bottle that I received the next day. No problems, no hemming and hawing. That’s “stand up” and I appreciate it. That type of thing will keep me coming back

Pretty Remarkable!

Delivers as promised. Saw measurable strength increases about 3 weeks into the cycle. Pretty remarkable considering I'm in my 60's.

Extra strength mainly

Nearing the end of 1 month cycle. Definitely feeling stronger. Most of my max lifts have improved about 10 lbs. My diet is usually on point, but this seems to be helping lose some body fat.

Would recommend

Gain weight and strength. Suppresses libido a bit. My 2nd course in two years. Very effective.

Working quicker than I thought

Decided to try 1-test for my first time prohormone cycle because of how mild it is and the positive reviews I’ve read. So far about 12 days in I’m noticing that my muscles are fuller and I have enhanced strength and endurance in the gym. I was originally only going to do 1 month but have been so pleased with the results so far that I ordered a second bottle along with Decaboin to stack with it. Hoping for even better results with zero side effects based on my experience so far. I’m very satisfied at this point.

At first was nervous that it would not work.I was worng tho it started working in my second week I could see good pumps in the gym and good strength gains in every week will be buying this product again

Chuck V.

The product is very good. I ordered it because I’m a 51 year old man and have been lifting weights for a couple of years now and I felt I needed that extra push. It makes my muscles feel harder, denser and I feel stronger as I lift. I also am better in the bedroom. I had a accident and put on some weight and felt that the product actually helped me lose weight faster. I am very satisfied with this company and it’s products
