Chiming in here too. My first-ever vial of the smaller reta size showed up yesterday, mixed it this morning, then ran the introductory half-milligram amount after lunch today.
Switching off every couple days with a 5mg tirz shot. Combining them deliberately, for reasons that make sense to me personally.
Figure I'll hold the half-milligram amount weekly for a month, then start climbing based on how things go. Running it at that pace, one vial should cover roughly ten weeks. The batch I just mixed is sitting in the fridge next to some compounded tirz I had ordered earlier through telehealth. All the shelf-life windows here fit comfortably within what I'm willing to risk.
The other nine unmixed vials, plus a ten-count box of the bigger tirz strength, are stashed in the chest freezer beside the moose meat.
Already planning to reorder a larger batch of both compounds down the road, since I'm figuring on another year and a half of dose adjustments ahead. Those, plus a few unrelated peptide buys, will land in that same freezer too, over by the ground venison.
