When I started using Tribulis (natural testosterone) my face and back broke out with acne. I had acne for about 6 months before I came across SkinB5, which is a powder that mixes with water or juice. I prefer to mix it with my protein shakes and it basically cleared my acne within 4 weeks.

Whilst taking SkinB5 I found it gave me tonnes more energy which is awesome for my training. Anyways if you have acne check out http://www.skinb5.com, My dermatologist also recommended using Cetaphil (cleanser), its really cheap and you can buy it from any pharmacy.
