I am not an expert in any of this, or a doctor, so take what I say with a grain of salt.
The front load phase of TB500 lasts 4-6 weeks, so if may not even have been fully in your system yet.
BPC157 you can run up to about 12-14 weeks before you have to cycle off for 4 weeks.
For both of these, I believe there is an "optimal" dose based on mcg/lb, and I believe you were running on the low end for both of them, although I would have to look it up and see what that dosage is, because I don't remember off of the top of my head.
6 weeks doesn't really seem all that long, however I did have noticeable improvement after only a week or two running both of those WITH HGH.
I recently stopped the HGH after 4-5 weeks (due to uncontrollable hand numbness, but in retrospect I think I upped my dosage too fast. I went from 2.5 IU/day to 5 IU/day in about 3 weeks) and it does seem that the healing has fallen off a bit. Once I feel the hand numbness is gone, I may hop back on and stick with 3-3.5 IU/day.
I don't know anything about science bio to say if they're legit or not.
Finally, I came back from a fairly significant lat tear that occured about 8.5 weeks ago and next week I'll be lifting at 100% capacity again. It has also helped heal up some other small nagging injuries that I had, so mine is definitely working.
