7, 3-Andro

A NO B.S. Formulation, Backed by Science.

When it comes to building lean muscle mass and cutting fat 7,3-ANDRO works wonders! This compound not only has zero estro conversion but it also combats naturally occuring estro while ramping up fat loss and increasing muscle mass. 7,3-ANDRO is formulated for the man seeking to combat muscle fatigue, increase protein synthesis and accelerate fat loss with minimal down regulation of his naturally occuring T.
All of our ANDROS incorporate LIPOSOMAL TECHNOLOGY to increase the bioavailability/potency of ingredients. Liposomal technology takes the active ingredients and encapsulates them in lipids (fats) to improve absorption and uptake into the body. This patented process enables 7,3-ANDRO to bypass stomach acids and allows for maximum absorption into the cells. The big knock against most anabolic agents is that they aren’t highly bioavailable in the body, DHEA pre-cursors included. Liposomal technology allows for maximum effects by the human body when administered orally.

Liposomal technology is not cheap, nor is the equipment. This is why you’ll rarely see it coming from a company who sells anabolics. Most companies who sell these kinds of supplements are selling a product of extremely poor quality.

7, 3-Andro FAQ

Take 1 tablet when you wake up, repeat this 10 hours later. Do this everyday for the entire cycle. Wait 30 minutes before eating after taking the Andro.

Yes! The 17A, 7,3, and 3Epi make a perfect stack for cutting fat and drying out while also making lean strength gains.

Easy, when you wake up take one tablet of each Andro, about 10 hours later repeat this. Do this everyday for the entire cycle.

Neither is required. Only thing required is Alpha, after completing a cycle.

4 to 8 weeks, upon completion start the Alpha.

Do not double up, just take 7,3 Andro when you can, and get back to your initial regimen.

We do not advise drinking alcohol on Andros, mainly because when we consume alcohol we suppress testosterone and the conversion of the Andros into testosterone.

7,3 Andro can be safely taken with ALL Steel products.

Upon completion of Alpha as post cycle therapy you can go back on for another cycle. We advise 4 additional weeks off before starting another cycle of Andro’s.


You must be at least 18 years old. However, we do advise people under the age of 21 to stick to effective mass builders such as Pumped and ADABOLIC.

You should wait 30 minutes before eating, you have slightly better absorption of the Andros on a empty stomach, but they still are effective even when taken with a small meal.

Most important is ADABOLIC, ADABOLIC has the necessary nutrients your body requires to put on the most mass in the shortest time possible. We also strongly recommend RESTED, RESTED increases the conversion rate of testosterone in the body and greatly boosts GH levels and recovery.

The side effects range greatly from person to person. Genetics, lifestyle, eating habits and other variables all contribute to the side effects or lack of side effects users experience. For most, Alpha is perfect for restoring the hormonal balance of the body and ensuring the user keeps the majority of their new muscle gains.
