Oh, I was not aware that by healing, you meant literal injury healing, not hypertrophy of muscle tissue.
Postworkout GH is transient and largely irrelevant.
Honestly, for connective tissue, you will find that low % ketosterone cissus and Epharm Joint Force will be far more effective than GH boosters.
That said, if you are set on a GH booster, try MST Somnidren GH Ultra + 1 cap slin-sane prebed.
