What to look for in a PG cream... short answer, avoid seed oils, look for bio-identical USP, micronized wild yam.

My understanding is that a bio-identical cream is considered bio-identical because it is processed and utilized in the body, identically, as if it is a natural hormone.

I think, but am not certain, that Lotus disapproved of a PG cream that I have recommended to others based solely on it having many different types of seed oils in it, not for any other reason. 

Seed oils are not healthy but I think that all PG creams have some seed oil in them. I would dare to day that people using female hormones are facing far greater risks than seed oils however perhaps I am not aware of how pernicious seed oils can be. The cream under suspicion was the "Now" brand and it was half the price of other PG creams, around $12 compared to $23. Otherwise, it is my understanding that a bio-identical hormone is exactly that, identical to natural hormones. 

Further, it is my understanding that there are two sources from which to produce bio-identical estrogen and progesterone -- soy and wild yam. 
Somewhere, I heard that wild yam is much preferred over soy but I cannot cite the reference. Some creams specifically note "no soy" in their ingredients.

There are two more things to look for. One, that the cream is USP certified, which I believe means that it is proven to be bio-identical, and two, that it is micronized, which I believe means that it is finely-ground enough to be easily absorbed through the skin.

I have seen people from UK mention iherb. Can you purchase PG from this site? https://www.iherb.com/

Everything that I say on this forum is based on hearsay. Proceed with caution.

Hoping that someone in the UK can give you a source for an effective PG cream and solve this.
