Hello dear @nicnaks , First of all, it depends on your weekly dose. As you know, the starting Ozempic amount is 0.25 mg once a week. Then you increase it to 0.5 mg by week 5. Thus, you may calculate the length of a 1 mg pen. The cost is different as well. Other sellers have different prices. I recommend contacting our trusted sellers directly and asking about the price and availability. You must also know that Ozempic 1 mg is the most popular dosage and is sold out very fast.
