Reconstituting from the same supplier but a different manufacturer is exactly the variable that creates the uncertainty on shot day. The 'I know what it's supposed to feel like' calibration from prior experience is the best tool for catching a potency difference early. What's the plan if this dose feels significantly different from your baseline?
If you want a gentler ramp up, try 2.5 every four to five days instead. Raises your baseline levels gradually, theoretically giving you steadier control, and softens the jump when you eventually move to 5.
Four weeks running 30 clicks followed by four weeks at 60? Once you've completed a full four weeks at 2.5mg, bump up from there only if actually needed.
Common starting approach is four rounds at the lowest strength followed by two at the next level up. Good news is needle tips are available both online and in physical stores without needing a prescription.
Start at the lowest dose, and if side effects are still rough, using a pen that allows adjustment lets you spread smaller amounts across several days within the week instead of one larger spike all at once.
Curious whether each weekly shot at that same starting amount started feeling progressively stronger by the fourth week? Read a few accounts describing that exact pattern, that the early results stacked and grew over several weeks rather than staying flat. Waiting eagerly for the higher amount mainly so the effect carries through all seven days instead of fading just as the weekend arrives.
That's odd... had you eaten anything ahead of the injection? Probably worth doing. When I was on 2.5 (now 5), it usually carried me 4-5 days before the cravings hit hard on day six. 2.5's typically just a warm-up dose to prep your body for the next level. I still managed to drop 14 pounds on it though.
