Buy T3 Online?

Please could someone pm me reputable suppliers so I can buy T3 online. I'm also requiring advice on dosage and what the minimal dosage I should start on please? Do I also decrease my levothyroxine or keep it the same? My Endo suggested putting me on T3 but wants more bloods first before writing to my gp. Then I'm worried my GP might not agree to prescribe it so thought I'd try to sort it myself than wait. Many thanks

What dose of levothyroxine do you take and do you have a copy of your latest blood test results with the ranges you can post.


Unfortunately I didn't get a print out but my TSH was 2.41 so my Endo increased it initially from 75 to 75/100 (but I just took 100) I've been back to him with emergency appointments as I'm having problems with thyroiditis confirmed by unltrasound so he increased it to 100 (based on my weight he said I should be on 100.80) after a couple of weeks. So been on 100 for about 4-5 weeks now. At first I felt better but now I'm feeling terrible and think I'm feeling hyper and the thyroiditis isn't easing. I didn't get my FT3 or FT4 but he says I had evolving thyroiditis and I wasn't converting and saw either my FT3 or FT4 was red. I'll call tomorrow and ask the secretary to fax overu latest results to my GP


If you aren't converting levothyroixine you need to be on T3 only. No use beating about the bush but I'm not sure how thyroiditis is treated and I expect it is painful.

Levothyroxine 'has' to convert to T3 and then get into our receptor cells, T3 is the only Active hormone and T4 (levo) is inactive.

It will be difficult if you have thyroiditis. I hope you get better quite soon.


So no wonder I'm not getting better just worse! I thought I'd seen some posts with ppl taking T4 and T3 together? I also thought the thyroid produced 4 hormones so not sure really how the body functions without any of them? As far as I know there is no treatment for thyroiditis tbh I'm getting to the strange I feel so ill I just want it out :(


Try to keep it as it might be worse without.

Before the introduction of levothyroxine we were prescribed NDT (Natural Dessicated Thyroid Hormones (from pigs or cows gland) and contain T4, T3, T2, T1 and calcitonin.

The Endocrinology Associations worldwide have now decided this is not to be prescribed, even though it makes many people better and was safely used since 1892. Also there was no CFS or ME of Fibro I believe when NDT was used so I think we should be allowed to try several thyroid hormone replacements if not recovering.

Some people don't feel well on T4 (levothyroxine) alone so sometimes T3 (liothyronine) is added and they feel much better. I think it's how our body reacts to synthetic or 'natural' and we are all so different.

Others try T3 only and some NDTs. I tried about 3 NDTs.


Thanks he said to trial T3 & T4 so fingers crossed my GP prescribes it and it works as something needs to help me x

It should be in a ratio of, I believe, 3 to 1, (T4/T3).
