I've just extracted and injected my bonus 5th shot of 2.5mg. I went with the extraction method rather than the forced twist method as I wanted to extract all remaining medication and measure it.
I managed to get about 0.75ml (a 2.5mg dose is 0.6ml) so I think this is about 3.1/3.2mg which I'm happy about as I wanted a bridging dose between 2.5mg and 5mg.
The needles I used are 1ml 0.33x8mm Plastic Multiple... https://www.amazon.co.uk/dp/B0C4HC51NY?ref=ppxpoppmobappshare
The needle was slightly wider and 2mm longer than the needles used on the pen but it was completely pain free. I primed the dose first before injecting.
So it will be interesting to see if I notice a difference this week. I'm not super hungry on 2.5mg but I'm trying to consume at least 100g of protein and I haven't lost any weight in the last week. Hope I start losing again this week. I'm 5'1 and currently 74.2kg down from 79.7kg from 6 March
