1.Is it ok to freeze tirz powder that are still in vials
2. Is 15 mgs that maximum safe dose for tirz?
3. Anybody here have any experience stacking Reta and Tirz? What was your dosage and how often were you injecting?
5. I’m getting tirz in 60mg vials, is pinning it too much going to introduce contaminants even if I’m wiping it down with alcohol swabs?
6. How long after recon will it be potent before it starts to degrade?
Thanks a lot guys for your input!
 
1. Preferable to freeze the powder. Better sterility and less degradation. But even room temperature is fine for 6+ months, based on Jano degradation testing by Jano and PAE.

2. More is probably fine, as some have done here. Studies (published) only go to 15 mg.

3. I have stacked all kinds of GLPs here and there. No issues, including with tirz and reta together. But 2 mg of reta was my max for stacking, like 1 mg twice a week. I am now trying reta by itself as of Monday. 2 mg of reta alone is going well, with good suppression and tirz-like sides (aided by some tirz already in my system).

5. No problems with 10+ pins over 90 days. Even 20 pins would probably be fine. The only issue I had once was coring the stopper with bad technique. Since then, I go into the stopper at an angle, at least when using a lower-guage fill needle.

6. A long time. 6+ months. Tirz is the roach of the peptide world. I still use compounded tirz that was reconned in March or earlier, with expiration in June.

1. Yes
2. It's the maximum currently approved safe dose. Larger doses are currently undergoing clinical trials, and many in the gray market community are pinning higher doses
3. Yes, many people, but not me personally (I'm not a fan of stacking GLPs)
5. If you use sterile technique, you should be okay
6. Longer than it will take you to burn through an entire vial
 
Thanks guys! Keep the replies coming!
Please excuse my butting in but in an effort to reduce redundancy in a forum with a search feature I think it's safe to say these two succinct answers represent the consensus of the community. You've been here since July so I'm sure these answers come as no surprise.

Yep, your questions are answered, lol and very well I might add!
