1ml gives me around 10 doses but it will vary slightly from person to person due to tolerance etc. RSO is strong stuff!
The key is to start very small - 1/2 a grain of rice is the usual suggestion (which I guess depends on what sort of rice!) - and see how you get on, increasing it as needed.
I just squirt a small amount onto a rizla, twist it up and swallow, or onto a biscuit and then eat that. Usually kicks in around 30-40 mins for me.
I find RSO much better for my pain than edibles, or vaping hash or flower. It gives a very nice buzz too, but the healing properties feel far more effective.
I'm aware it might not work for everyone - and for every type of pain - but the impact on my bad back felt almost miraculous the first time I used it, and I then noticed my sleep and mood also improved. It's all I use now for back pain (if I don't have to do much - it wipes me out!). I always have some in and don't bother with GP prescriptions any more.
Pollyโs recommendation above is a good one - Your Natural Medicine have been here for ages (in various incarnations) and are reliable. Their RSO is decent - nice and thick and strong - and comes in good quality glass syringes, which are easier to use, and dose more accurately, than some of the skinny plastic ones.
Hope you manage to find and choose something that works - I can see lots of people are recommending here - but RSO may be your best option if the main purpose is therapeutic/medicinal
