I'm new here. While reading up on PepPedia (fingers crossed that it's a trustworthy place for info), I came across a claim that corticosteroids—glp's included—can interact with peptides and potentially lower how well they work. Every day I use Flonase, and a few times each year I get injections in my neck and back.

Flonase is something I could swap for something else, and I might be able to stretch out the gap between my neck and back injections. My orthopedic doctor is aware I take Tirzepatide 12.5/mg but hasn't mentioned anything, and neither has my weight loss doctor. If I'd known back then, I would have brought it up with them.

Does anyone have experience, knowledge, or thoughts on this?

Eventually I'd like to begin cjc1295/ipamorelin, but I'm unsure what the implications would be. Perhaps in real life it's a nothingburger...?!

Thanks so much!

For months I've been taking 7.5mg of tirz. During that stretch, I got a cortizone injection in my shoulder last October, and just last week I had a nerve block in my neck. I haven't noticed any problem with it whatsoever. My weight - whether dropping or not - hasn't been impacted. I don't pick up on any interference or interaction at all. ymmv
 
Hey, really appreciate you getting back to me! From what I can tell, that interaction caution seems aimed at folks taking something like methylprednisone every day. With Flonase, that's not really the case. My allergies are loving it! Thanks again for responding.
 
With shots given so rarely, there's no real need for concern. Because the nasal spray acts locally, the amount that actually enters the bloodstream tends to be minimal and unlikely to trigger problems. That said, in cases of more serious asthma or COPD, high-dose inhaled steroids can certainly matter and may even contribute to weight gain. For hay fever, however, the doses are typically far smaller—still, checking into it is a reasonable move. As you pointed out, though, it's generally oral or injected corticosteroids that lead to the bigger issues.

For those who've had injections for some time, the degree of relief they provide is already familiar. (Cortisone and I go way back.) When the effects of a shot begin to fade, that might be the moment to introduce CJC/IPA and check whether pain eases before the next round of injections. So far I haven't seen peptides lose any of their benefit following a Cortisone injection, though for me most peptides are gentle when it comes to lowering inflammation — still, I'll take whatever assistance I can get.

(PPS) Pentosan Polysulfate Sodium. This is a drug under investigation for osteoarthritis (OA), especially for cutting pain and inflammation in the knees. It has been prescribed to humans for decades for interstitial cystitis, and now subcutaneous injections of PPS are being fast-tracked by the FDA specifically for OA, with Phase 3 trials underway to assess improvements in pain and function. Horses have received it for ages, and my dog is on it too, through the vet of course. It works systemically and may slow cartilage breakdown or help build it up. I personally take Tadalafil (Cialis) 5mg 2X daily to boost blood flow and help it reach my back, extremities, and so on. Pentosan can be a costly slow burn, since I get it from a Compound Pharmacy. Nsaids are off-limits for me, so I'm leaning more toward Ablations for my neck and back, because Cortisone simply degrades soft tissue.

(TA1) Thymosin Alpha-1 is a peptide the body produces on its own, mainly from the thymus, and it helps regulate the immune system. The thinking is that allergies stem from a Th2-dominant immune response, which drives IgE and histamine release. TA1 may help rebalance immune signaling and improve tolerance, rather than just ramping up immunity. That part rests on real biology. What's less established is how much this actually lessens allergies in real people. Most data is mechanistic or comes from small studies, not large trials. So it's promising for immune balance, but not yet a guaranteed fix for allergies or symptoms. I happen to have a somewhat low white blood cell count, and supposedly this can help with that too. I'm doing 1mg a day for 3 months to see if it helps in that regard. Luckily, I don't have Allergy issues.

Thanks so much for getting back to me — it really helps! Between this forum and others, I keep picking up new information about approaching gap's and similar compounds with knowledge rather than impulse.

This is all useful to me. My right hip has "moderate/severe" OA, which is a real problem. I also have an actual IC diagnosis. It's good to learn about Tadalafil and the TA1 peptide. Where I live, allergens are brutal for some people, myself included. There's a lot of info for me to look into and absorb! That's the reason I'm here.

Thank you for answering me!
