Imedical has always been super solid for me but unfortuntely have never come across a discount code.
Was gonna try out meditests they have a 10% off first customer discount and they seem to be solid too similar to imedical based off what ive read
imedical is far better than roidsafe. Their BB3 panel is a great starting point because it covers a solid range of key blood tests. You can easily add extra tests depending on your individual needs and what you're monitoring.
