You and your sweet little Tasmanian devil are doing great but ohhhhh, I hate that you are having to battle so hard – the fatigue, the lack of your former motivation to work out ... and that most dread scourge, the one I personally have shockingly little patience for: " slow weight loss."
All of which is to say, you don't have to let your freezer stash of Reta stop you from trying something you would otherwise try.
This is the gray market, and there's always a way for you to do what you want to do.
Don't have the spare cash to buy Tirz? TRADE Reta for some! Not sure Tirz will help you anyway? Just get a vial or two to start out!
So many of us have stocked up on one peptide only to find at some point that we wanted/needed/were tempted to go in another direction.
There are probably people on this forum right now who have years' worth of Tirz in their freezer, but have switched to Reta. There are trustworthy small resellers among us who will ship you a half-kit for relatively little money.
If you think there's a chance that Tirz might make your life a little easier and your weight loss a little faster .... I hope you will consider giving yourself the opportunity to find out. You have earned it and you deserve it.
Hug that little devil of yours for me, and give his mommy the break she deserves
