ya, my doc tries to push injections over nasal or gel. drs love consistent levels. Natesto is cool too some folks hate it but some folks love it. you feel it in minutes and gives u energy/confidence/strength and also helps sleep better IMO. id front load ur day vs taking it 6-7 hrs before bedtime as to keep natural night pulse and all the extras u get from not being totally shut down.
I mean some folks prefer gels so all good if feel good. some generic gels are more alcohol based from my understanding and evaporate(soak in) faster.. I mean try cheaper one if dont like it try other NBD. if both dont help say u would like to try Natesto or injections as either there not working or say its problematic to dose daily and/or your wife/kid/neice/nephew always touches/hugs ur legs at family bbq and causing issues in your relationships. or might work just fine for you, as there are a few advantages of creams/gels over injections.
good luck man!
