Do I take advantage of the discount code for MJ or wait

I started MJ not long before the price increases were announced and starting my second 2.5mg pen tomorrow. It’s still working well but I do feel I’ll need to move up. Would like to ease in at 3.75mg on 5mg pen then move up. I don’t plan to go above 5mg due to cost.
I managed to get two 5mg pens from my pharmacy and another one before 1 September. I’ve been offered a discount code for MJ £25 off but I need to use it by Monday and I was considering getting an extra 5mg pen.
I don’t know how I’ll react at 5mg so would this be a mistake or shall I just get it and then I have 3 months stock and then review after?
I don’t have money to burn, I’ve put it on my credit card and was gonna pay them off monthly. Not sure what to do. Gutted these increases happened at the start as I wanted to buy per month but I know I won’t be able to continue at full price.

You already have several pens, and you really won’t know if you can continue on 5mg or need to step up. £25 off is not a huge discount. You can get decent discounts still from lots of pharmacies as a new customer. You’ve already put the costs onto your credit card, so I would just hold off a bit until you know how you’re doing and what strength pen you might need in a few months time.

Your already in debt as you cant really afford them, why put yourself in more debt when you already have enough for now? £25 isnt really much.

Argh you’re both right. I think I was feeling anxious and carried away in my head. I am thankful I have the funds to pay back my CC for the pens I’ve bought when I get paid next two months and then will be able to purchase one a month so will wait and see how I get on with the 5mg in a few months then decide what to do.

Agree with pp, I wouldn't buy more until you know how you are going to respond.

I would stay as low as you can for as long as you can. If 2.5mg keeps working I would stay on it for longer that this pen, if/when you move up to 3.75mg stick to it for 3-4 weeks until it has built up that level in your system to see if you can stick to 3.75mg for a while (I've been on 3.75mg for 14 months now). This will give you 5mg available as the next step up later.

Also 3.75mg will allow you to get 5 doses out of the pen before it locks which is another saving.

Last point is work with Mounjaro to stay on the lower doses. Sticking to the basics consistently will help - protein at every meal, complex carbs, reduce sugar/sweeteners/UPF/simple carbs. At least 2L of water a day. These will all help Mounjaro do its thing and might (doesn't work for everyone) allow you to stick to lower doses for longer.
