I used the DP TestP at 1ml ED and by first week it was very clear that I was using high quality testosterone. I noticed increased in libido, very oily skin and a "sense of well being" that testosterone brings when used. My aggression also was noticeable in and outside the gym. There are mixed feedbacks with DP products, but I personally have not any issues with any DragonPharma products. I continued the protocol with Maxtreme Pharma TestP amps after the DP ran out and am very well pleased with Maxtreme also. It was my very first time with that particular lab and I did not notice anything that would suggest a "drop" in testosterone levels when switching from DP to Maxtreme. Thank you so much OSGear for allowing into your TestP promo, I very much appreciate it and you definitely have my business for my future needs.
