Goin off a chat j had way a mate a few weeks ago, he paid 40 for the first pin prick blood test, then if that’s low enough you need a second test done( as uk needs 2 low tests before they can prescribe), second one tho gets took by a person an cost 100 or summat or you can sort it yaself an they test it for cheaper, then I think it’s a test every couple/few months after that to keep up with it
he reckoned he was low on everything, blaming hormones an vitamins And everything he could, same age as me, but they told him although his levels were sub optimal, he wasn’t low enoug
