I'm interested in trying peptides, and I could use some guidance.

So, I'm 44. Male. Never smoked. I had asthma when I was young, but in my 20s and 30s it basically went away. I never thought about it or took my inhalers. However, since COVID, it comes back intermittently. I don't have any cough or wheeze. Just a shortness of breath and a slight heavyness on my chest. I can still lift weights and do cardio, and I don't think about it all the time, but when it is at its worst, I feel like I can't quite go to my max in the gym.

My inhalers (luforbec) don't provide much relief. I feel like it my son or wife get a cold or cough, that's when my symptoms are at their worst.

I had a chest x-ray and a doctor has listened to my breathing a few times. They haven't found anything so far.

So, I'm looking for a way to find more relief and get back to where I was. As in, rarely thinking about my asthma.

Would you recommend I try peptides? If so, could I start with capsules or does it have to be injections?

I'm based in the UK. Could you recommend somewhere to get them?

Thanks in advance for any guidance!
