I always urge caution when dealing with treatments promoted via Webinar, and linking you to specific practitioner or clinic. I looked up Reginald Archibald and his certifications say he is a Licensed Acupuncturist, has a Diploma in Oriental Medicine, and is a Functional Medicine Practitioner. He is not a doctor as far as I can see.
I cannot say what you ought to do, except to be very cautious. Also, find out whether this therapy is covered by your insurance (some Peptide therapies are covered by some policies when prescribed by an MD as part of a course of treatment.) I personally would not be comfortable reaching out to such a practice for treatment. My approach would be to consult my primary & pain docs for a referral to an MD practice using Peptide therapy.

Can you tell me about your consultation with them?
