@hellohellooo some things to consider when using the pens
You don't need to increase your dose until you want to. Only increase when you find it difficult to keep to your weekly calorie deficit for a couple of weeks as suppression can come and go.
For any strength of pen each full dose is 60 clicks / 0.6ml. You can "unofficially" take partial doses by adjusting the number of clicks or using a syringe and adjusting the ml (google 8mm 1ml 32G and buy from a medical supplier not amazon). If unsure of the maths ask here.
desired dose / pen dose * 60 clicks = number of click
e.g. 7.5 / 10 * 60 = 45 clicks
I have a spreadsheet click chart I can send you if you pm me your email address.
Each pen holds 3ml. Enough for 5 full doses on days 0,7,14,21,28 so within the 30 day limit. The pen locks after around 257 clicks (including priming) so you can't get to the 5th dose. Access using either hard twist or a syringe (never use a needle more than once).
If you are taking partial doses you could potentially have enough for a 6th dose on day 35. It breaks the discard after 30 day rule, but I am personally ok with that if I keep my pen in the fridge. You need to assess the risk for yourself.
Stick with the 7 day dosing schedule for regular injections unless you speak to your provider (although I'm not sure how supportive Voy actually is at giving individual advice - they should be at the prices they charge! - if you are looking at other suppliers check out monj. co.uk for a list of safe registered pharmacies, prices and trust pilot ratings). If you miss one/want to change injection day the instructions in the box will guide you.
If you are not sure of anything ask here, there are a lot of supportive users on this thread who have gained knowledge over time and you will too. Just be careful and think through any unofficial advice given to assess for yourself if it is low or higher risk as some posters are less risk adverse than others.
