Long-term plan: switching from Mounjaro to high-dose Ozempic (Wegovy protocol) after poor early response + stockpile situation. Am I crazy?
So I've been cooking up a long-term GLP-1 strategy that fits my financial reality and weird response pattern. I'd genuinely like to hear if this sounds stupid, dangerous, or maybe even reasonable. I know it's a lot, sorry in advance.
41 BMI, uncontrolled T2DM, MASH with liver fibrosis, systemic inflammation. I need to drop ~30 kg to get anywhere near a healthy range. So this isn't cosmetic—I'm trying to save my liver and pancreas.
I started Mounjaro (tirzepatide) 7 weeks ago. I did the usual 2.5 mg for four weeks, then 5 mg for another four. Just finished the last 5 mg shot. The problem? Zero appetite suppression. I mean nothing. Food noise still there, hunger unchanged.
Last year I briefly tried Ozempic 0.25 mg and it was completely different—appetite vanished within days. So my body seems to really feel pure GLP-1 agonism but isn't registering the lower GLP-1 component in tirzepatide at these doses.
Why I think this makes sense pharmacologically:
From what I've read, semaglutide is about 5 times more potent at the GLP-1 receptor than tirzepatide. In terms of pure GLP-1 activation, 1 mg semaglutide is roughly equivalent to 10 mg tirzepatide. Tirzepatide's superior weight loss in trials comes from adding GIP, but that GIP synergy seems to only fully kick in at 10-15 mg. Meanwhile, semaglutide also has a 7-day half-life vs. tirzepatide's 5 days, so it builds up to a more stable steady-state level in the body. I suspect that's part of why even low-dose Ozempic hit me harder—more constant GLP-1 activation.
Mounjaro is insanely expensive for me out of pocket. Ozempic is covered by government hospitals in my country. Through some loopholes and multiple hospital visits, I've managed to accumulate:
· 31 × 1 mg Ozempic pens
· 1 × 0.5 mg pen
· 1 × 0.25 mg pen
All with long expiry dates (2028+). I also have a limited Mounjaro supply left: the original 15 mg pen I started (which still has its overfill) plus 3 new 15 mg pens (no overfill). That's it—4 pens total.
My plan in a nutshell:
- Finish Mounjaro titration using the 4 pens I have. I've already done 2.5 and 5 mg. Now I'll do 7.5 mg (4 weeks) → 10 mg (4 weeks) → 12.5 mg (4 weeks) → 15 mg. By my math, I'll get about 6-7 weeks at the full 15 mg dose before the pens run dry (late September 2026). I'll extract the overfill from the first pen as a bonus final shot.
- Wait 7 days, then start the Wegovy schedule using my Ozempic stash. 0.25 (use the 0.25 pen) → 0.5 (0.5 pen) → 1.0 (fresh 1 mg pen) → 1.7 → 2.4 mg, all via click counting on the 1 mg pens.
- For the higher doses I'll do multiple injections on the same day, always with a fresh needle. For 1.7 mg: one full 1.0 mg shot + 0.7 mg (50 clicks) from the same pen. For 2.4 mg maintenance: I'll keep two pens open. Pen A gives my two 1.0 mg shots (lasts 2 weeks). Pen B gives the single 0.4 mg shot (29 clicks, lasts 10 weeks). So each week I do 3 injections. I've mapped out the exact pen usage week by week, and my 31 pens will last exactly 63 weeks (16 weeks titration + 47 weeks at 2.4 mg), taking me from October 2026 to late December 2027.
I've thought about going to 7.2 mg someday, but not now—just 2.4 mg, which is the proven high-efficacy dose.
So my questions to anyone who's done similar:
· Multiple injections from one pen in a single day: I know it's off-label. How risky is it really if you use a new sterile needle each time, keep everything clean, and visually check the liquid? Does the pen mechanism actually hold up to being used 3 times in one day? Any infections or failures?
· Switching from max-dose tirzepatide to semaglutide: Anybody else make that jump? Did appetite suppression come back strong? I'm worried I'm abandoning tirzepatide too early, but I can't afford to stay on it forever.
· Using an Ozempic pen for 10 weeks (the Pen B): The manufacturer says discard 56 days after first use due to preservative. I'd be going a tiny bit beyond that. Real-world experience? Anyone done this long-term?
· Overall sanity check: Does this plan sound remotely reasonable given my health situation (MASH, fibrosis, DM)? I'm under a doctor's care generally, but they don't know the full details of my multi-pen setup. Am I missing any glaring danger?
I know this is a wall of text—thanks if you read this far. Just trying to make the best of a weird situation where I can get one med for free and the other costs a fortune, while my body seems to prefer the free one anyway.
