hGH helps with repair and many people that use hGH/peptides have noticed improvements in old injuries. Right now SupplementJunkie is using these patches to help recover from surgery, and while it's not miraculous it appears to be helping him. I am feeling improvements in my shoulder and wrist which have been nagging for the past 6 months. I think you could start noticing improvements anywhere between 1-3 months, but hGH will take time regardless.
If you want to try for 30 days and see if it helps at all, you can do that. If it's not helping at all, you can get a full refund as long as you request it within 30 days of your order.
