Pine Pollen is completely natural and no PCT or cycle support of any type would be needed.
Pine Pollen itself is considered to be an adaptogenic herb and superfood that is loaded with vital antioxidants such as amino acids, vitamins, minerals, enzymes, and much more.
Epiandrosterone can be extracted from Pine Pollen BUT that doesn't meant that Pine Pollen has a high concentration of it without a specialized extraction process. Hence, the high price of Epiandrosterone for a much lower dose than Pine Pollen - the large amount of starter material that would have to be used to reach that amount of extract. Basically, you could/would never consume enough Pine Pollen to equal a large dose of Epiandrosterone.
Here is a comparable example - Green Tea is great and very well-known for its many overall health properties and it has a lot of great constituents that can be extracted from it, including VASO6, Epicatechin, & EGCG. However, you would never get enough of any of those to be effective just by consuming Green Tea or taking Green Tea Extract (except EGCG you may with the extract). However, just because you don't get VASO6 or Epicatechin in effective doses from your normal Green Tea doesn't mean that it isn't a great ingredient.
I hope that makes sense.
