Sorry if this has been asked/discussed before.
I am currently trying to look at all alternatives available to me:
I am seeing a so called Hertoghe doctor in Belgium and can get a prescription for either Armour or Erfa (the only two NDT drugs available in some Belgian pharmacies). Neither drug is optimal for me. Also, given the price of NDT in Belgium, I would only be willing to pay for something extraordinary, not something that works only marginally better than T4 drugs alone.
It's a shame what happened to Erfa; the reported problems seem to have started around the time I was switched from Armour to Erfa...
I have been on Thyroid-S from Thailand for about six months, and feel OK but not great. Even on high doses, my FT4 is at the bottom of range and my FT3 levels midrange at best. That is exactly what my FTs looked like on (high doses of) Armour. My doctor said that does not matter as long as my TSH is suppressed because, to quote doc: "Your suppressed TSH shows that the medication is working".
This seller of Thyroid-S does not charge as much as pharmacies in Belgium do for prescription NDT, but is more expensive than Thai suppliers. On the other hand, knowing that delivery can be guaranteed makes it worth it.
The reason I chose Thyroid-S over other Thai brands is because it's available from a seller in the EU, so it will be shipped as an intra-community delivery.
I really don't like the very long list of fillers for Thyroid-S (are a dozen or so fillers really necessary?), but the fact remains: when I search the net for reviews, most if not all are positive. Very few users seem unhappy with the product. But to me, it feels exactly like Armour did back in 2011 when I was first put on it: first, a rush of warmth and energy which disappears after a couple of days, then comes back after every raise, only to disappear again, so I never seem to stabilise on either brand. Could cellulose be the reason for that?
I recently contacted one pharmacy in Belgium carrying NDT, and was told they cannot order any other brand (Naturethroid, WP, NP...) if the script is for Armour or Erfa...the reason I was given is that those drugs are NOT interchangeable...so using the doctor's prescription to order NDT in Belgium is not an option for me, unless I choose to go back on Armour or Erfa.
I have located a seller of the other Thai brands based in Thailand who has found a way to deliver the goods without problems but, before I go down that road, and decide to try yet another brand of porcine NDT, I have been asking myself if I should give Thyrogold a try...? The main reason I've been hesitant is that it contains bovine and not porcine thyroid, and the latter is said to be closer to human body chemistry. However, since most adrenal support products (both ACE and glandulars) come from cows, I wonder if that is really reason enough not to try it...plus I like the fact that Thyrogold contains few fillers, and no cellulose.
Is there any evidence that bovine hormones act differently than porcine hormones once in the human body? Is there any reason why Dr. Lowe, very knowledgeable about thyroid disease, would choose bovine thyroid hormone over porcine (availability? cost? etc)
Inspired by many posts (here and elsewhere), I briefly tried T3 only a couple of years ago, but felt terrible within a week. It's obvious to me that I need both T3 and T4, and I am still hoping I will be able to make some brand of NDT (be it porcine or bovine, prescription only or OTC) work.
