[Markee]

Reading these 2 below threads got me wondering if anyone knows the difference  pros and cons between the two the devices  the DHI Choi pen which also seems to also  be offered by Dr Clinik vs Koray's KEEP ?

Very interesting to see Keep.

I am the patient in your 2nd link who had the DHI implants via Choi pen - I've had a huge explosion of growth at 11 weeks (just before 3 months), but fingers crossed for further growth. I had thought this was due to the 2 PRP treatments I had but now also thinking that the DHI technique probably also helped (as the Doctor claimed - faster and better recovery).
