Recovery Peptides
Tissue repair, tendon and gut healing compounds, and how much of the evidence is still preclinical.
Recovery is the category where the gap between reputation and evidence is widest. BPC-157 and TB-500 are among the most discussed compounds anywhere, and both rest almost entirely on rodent and in-vitro work: no completed randomised human trial exists for either. That is not an argument that they do nothing, it is a statement about what has been measured. The grades below reflect study design, not popularity, so a compound with a strong mechanism and no human data grades low here.
BPC-157 + TB-500 Blend
B-gradeA single-vial blend of BPC-157 and TB-500, local plus systemic tissue repair in one convenient injection.
BPC-157
C-gradeA synthetic peptide derived from a gastric protein, used for soft-tissue healing, gut repair, and reducing inflammation.
KLOW Blend
C-gradeA single-vial 4-peptide blend combining GHK-Cu, KPV, BPC-157, and TB-500, the most comprehensive of the popular research recovery blends.
TB-500
D-gradeA synthetic fragment of Thymosin Beta-4 used for systemic recovery, muscle repair, and improved flexibility.
NAD+
C-gradeA naturally occurring cellular coenzyme central to energy metabolism and DNA repair, sold as an IV, injectable, and oral longevity supplement.
DSIP (Delta Sleep-Inducing Peptide)
D-gradeA nonapeptide originally isolated from rabbit brain, studied for its role in inducing delta-wave (deep) sleep.
Glutathione
D-gradeThe body's master antioxidant tripeptide, sold as an IV/injectable and oral wellness supplement for detox, skin, and liver support.
KPV
D-gradeA synthetic tripeptide fragment of alpha-MSH studied for anti-inflammatory effects without the pigmentation or arousal effects of full melanocortin agonists.
Larazotide
D-gradeAn oral zonulin antagonist that holds the gut's tight junctions shut against gluten, a celiac-disease drug candidate, not a general gut-health peptide.
LL-37
D-gradeThe human cathelicidin antimicrobial peptide, part of the body's first line of defense against infection, studied for wound healing and immune modulation.

Recovery peptide questions
How many recovery peptides are there?
This library covers 10 recovery compounds, each graded from S (regulatory approval) to F (no usable evidence).
Which recovery peptide has the strongest evidence?
BPC-157 + TB-500 Blend carries the highest research grade in this category at B. A single-vial blend of BPC-157 and TB-500, local plus systemic tissue repair in one convenient injection.
What does the research grade mean?
The grade describes how well a compound has been measured in humans, not how well it works. S means regulatory approval; D means animal data only. Popularity and anecdote do not affect it.
