I'm a 52 year old man mainly using pine pollen for its testosterone boosting properties for sexual performance. I exercise daily (mainly running) and have noticed a slight increase in energy and a big increase in sex drive and all aspects of sexual performance. 3/4 tsp in the morning and 3/4 tsp at night (twice daily) for 5 days on and 2 days off cycle. I put the powder under my tongue till it dissolves (approx. 1 or 2 minutes). Working great so far - only 2 weeks using the Lodgepole pine pollen. The company gets five stars as well. Very professional website and videos available on Youtube. Good customer support - I am from the United States and had a question which was answered via email in 48 hours. From the videos and website, my perception of the company is one of professionalism, an honest interest and passion for their product, and competence.
