For gut-focused protocols in particular, oral is not a compromise — it is the point. BPC-157 and KPV both act on mucosal tissue, and ZestyRat supplies both as capsules alongside the vial. The rest of this list is small molecules that were always oral: rapamycin, MK-677, tesofensine, fenbendazole, dihexa.
The original GLP-1 receptor agonist — the reference compound in metabolic research, now also available as an oral capsule and as a co-formulation with BPC-157.
Small-molecule NNMT inhibitor investigated for its role in adipocyte metabolism and NAD+ salvage. 50mg, 30 capsules.
ERR agonist studied as an exercise mimetic — one of the more interesting recent additions to metabolic research. 350mcg, 60 capsules.
Triple monoamine reuptake inhibitor studied for appetite regulation. 500mcg and 1mg capsule strengths.
The most-requested research peptide there is. 10mg lyophilized vial or 500mcg oral capsules for gut-focused protocols.
Tight-junction regulator studied specifically for intestinal permeability. 350mcg, 60 capsules.
The C-terminal tripeptide of α-MSH, studied for anti-inflammatory signaling. Vial or 30-count capsules.
Orally active ghrelin mimetic — no injection, no reconstitution. 10mg and 25mg capsules.
Angiotensin IV analog studied for hepatocyte growth factor signaling and synaptogenesis. 2mg / 5mg / 10mg.

Our own line is in development. Until it is finished this site does one job: send you somewhere we would order from ourselves. That is ZestyRat, and it is not a close call — 47 orders have been placed through our links, 30 of them in the last month, and every order that cleared checkout has shipped. Not one has gone missing.
Ratings on this page are our own editorial assessment, based on published COA practice, checkout and shipping experience, and price tracking. We earn a commission on orders placed through our links, at no extra cost to you. Research use only.
