Muscle Growth & Recovery
Peptides commonly studied for their effects on lean mass, training recovery, and connective-tissue repair.
Many of these are growth-hormone secretagogues or repair peptides studied primarily in animals; human data are limited.
BPC-157
Animal / LabA 15-amino-acid fragment derived from a stomach-protecting protein, widely studied in rodents for gut, tendon, and ligament repair.
TB-500
Animal / LabA synthetic fragment of thymosin beta-4 studied in animals for wound healing, cardiac repair, and tissue regeneration.
Sermorelin
Limited Human EvidenceA 29-amino-acid GHRH analog formerly FDA-approved for childhood growth hormone deficiency.
CJC-1295
Limited Human EvidenceA long-acting GHRH analog studied as a research peptide for sustained growth hormone elevation.
Ipamorelin
Limited Human EvidenceA selective ghrelin receptor agonist studied as a growth hormone secretagogue with minimal effects on cortisol or prolactin.
MOTS-c
ExperimentalA mitochondrial-encoded peptide studied for its role in metabolism, exercise capacity, and mitochondrial signaling.
Tesamorelin
Strong Human EvidenceA long-acting GHRH analog FDA-approved as Egrifta for HIV-associated visceral fat accumulation.
MGF
Animal / LabMechano Growth Factor (MGF) is a locally-acting splice variant of IGF-1 (IGF-1Ec) studied for its proposed role in activating muscle stem cells and triggering early muscle repair after mechanical loading. Evidence is almost entirely animal and cell-culture based, with no human therapeutic trials.
CJC-1295 + Ipamorelin
ExperimentalA popular research-peptide stack pairing the GHRH analog CJC-1295 (no-DAC / Mod GRF 1-29) with the selective secretagogue ipamorelin, intended to amplify natural growth-hormone release. No human trials exist on the combination itself.
Tesamorelin + Ipamorelin
ExperimentalA research stack combining tesamorelin (an FDA-approved GHRH analog for HIV-associated visceral fat) with ipamorelin, aimed at fat loss and growth-hormone support. No human trials exist on the combination itself.
Wolverine (BPC-157 + TB-500)
ExperimentalA recovery-focused research blend pairing BPC-157 with TB-500, marketed for soft-tissue and injury repair. Both components have only animal-level evidence, and there are no human trials of the combination.
Wolverine+ (BPC-157 + TB-500 + MGF)
ExperimentalAn extended recovery stack adding Mechano Growth Factor (MGF) to the BPC-157 + TB-500 blend, aiming to layer muscle-stem-cell activation onto tissue repair. All three components are animal/lab-level only, with no human or combination trials.
