Great price, great product

Added about six pounds of muscle on first cycle. Wife definitely noticed a difference. Re-ordered.

Works well

Product works well for growth but also increases my appetite and I gain weight when I'm trying to gain more definition

Decent Results

So Far I m 16 days in and seeing some decent results, I’m only giving 4 stars because my expectations were a bit higher. I have gained a solid 3-4 lbs of muscle in 2 weeks. I’m probably going to be around 7 lbs in total for the 30 day cycle

Usually start seeing results going into the fourth week. Plan on ordering another months worst buy lost my discount code

Still early

I've only been on this stack for about 2 weeks, and it's too early to see any gains, but I HAVE increased my weight and reps already. I had rotator cuff surgery about 4.5 months ago, so am trying to rebuild the strength I had before. This stack seems to be helping make faster progress. I'll be doing PCT afterward, then trying some other anabolic supplements, but will likely come back to these, simply based on price, if nothing else.

If you want to use something that will actually assist you without going cycle city this is top shelf. Also feel more energized after working out which helps with the rest of the day.

So... if this is a placebo than this is the most effective one ever. I took this stack for 6 weeks so far, trying to lose weight and build muscle. I burned fat for sure. I started off at 194. I stepped on a scale last week, first time in 6 weeks, just cause I wanted to be surprised, and I’m at 208. Stronger, healthier, all around more muscular. Pretty neat stack. Recommend the 8 weeks.

Great product. One pleasant surprise was the way it helped my mood.

Calvin L.

Very Effective

So lets cut to the things you want to know. Well you muscles grow fast? Yes. Will you recovery from workouts quickly? Yes. Will your strength grow alot? Yes. Overall i had a great experience on this product. You ask why the 4 stars instead of 5. The drowsy-ness that comes with this product stack is a bit much. Youre going to need something throughout the day to keep your energy up. I think i'll do 3 to 4 weeks cycles on this because of that. Plus i was crazy hungry. Im going to use it again.

Best stack

I love these two items. This has been the best stack This is the best stack I have taken from high tech pharmaceuticals. I’m stronger, more cut, and very vascular. I do suggest getting 2 bottles of each. I’m almost out and I feel as if now I’m getting good gains. 4 bottles should be just right.

Taylor W.

I love Hi tech supplements. Solid muscle gain with 1test and decabolin.

Brandon T.

The 1-T is great by itself, add the "deca" for even better results
