Peptide Stacks and Research Protocols
Peptide research rarely uses a single compound in isolation. Combinations — "stacks" — are the norm in preclinical literature because biological pathways intersect. Here is a catalog of the most-studied stacks, grouped by research focus, with the rationale for each combination.
Tissue repair research stacks
Wolverine Blend
Most-studied tissue-repair combination. Complementary mechanisms: BPC-157 engages vascular/gastric repair via VEGF/NO; TB-500 drives cell migration via actin dynamics. Used in tendon, gut, muscle, cardiac preclinical models.
Ask about Wolverine →Glow Blend
Skin, hair, and dermal tissue research. Adds GHK-Cu's broad gene expression modulation (4,000+ genes in cell models) to the Wolverine base. Common in dermal-focused preclinical work.
Ask about Glow →VIP + BPC-157 Tablets
Oral tablet format. VIP (Vasoactive Intestinal Peptide) plus low-dose BPC-157 for gut-focused research protocols where oral administration is preferred.

CJC-1295 no-DAC + Ipamorelin
Classic GHRH + GHS pulsatile research stack. Short-half-life GHRH analogue with selective GHS. Synergistic GH release while preserving natural pulsatile rhythm in preclinical models.
Request info →Tesamorelin + Ipamorelin (10/5mg)
Tesamorelin's visceral adiposity research profile (40+ preclinical studies on trunk fat) combined with Ipamorelin's selective GH release. widely cited adiposity stack.
Request info →Tesamorelin + Ipamorelin (5/5mg)
For research protocols preferring lower Tesamorelin dose. Same pathway as 10/5mg variant.
Request info →3X Blend
GHRH + GHS + local IGF-1 variant research. Three-peptide combination targeting GH release plus muscle satellite cell activation pathways.
Request info →4X Blend
Four-peptide research stack adding GHRP-2's strong GH-release magnitude to the 3X base. For preclinical research requiring maximum GH pulse magnitude.
Request info →Cognitive research stacks
Multi-pathway cognitive research: Dihexa (HGF/MET synaptogenesis) + Tesofensine (triple monoamine reuptake inhibition, attention) + low-dose BPC-157 (neurovascular support). Orally administered.

Frequently asked questions
The BPC-157 + TB-500 combination (available as SMART MD's Wolverine Blend) is the widely cited tissue-repair stack in preclinical peptide literature. For GH axis research, CJC-1295 no-DAC + Ipamorelin is the widely cited GHRH + GHS pairing. For adiposity, Tesamorelin + Ipamorelin dominates.
Biological pathways intersect. Single-compound protocols often engage only one node of a multi-pathway process. Combinations target complementary nodes — for example, GHRH + GHS engage different receptors both upstream of GH release. In preclinical models, combinations typically produce larger magnitude effects than either compound alone at equivalent doses.
Pre-dosed blends offer dosing consistency (no pipetting error between vials) and convenience. Separately-purchased compounds offer flexibility in the exact ratios used. For researchers replicating published protocols with specific ratios not matching a pre-dosed blend, separate compounds are necessary. For standard research protocols, pre-dosed blends reduce error sources.
Combined formulations are documented the same way as single compounds: each component is verified individually and the combined vial carries its own lot COA. Researchers who request them typically cite consistency across preclinical work; a SMART rep can walk through the documentation for any combination.
Yes. All peptides and blends at SMART MD are legal to acquire for research purposes in the United States. They are classified as research-use-only compounds. See our legality guide for the full regulatory framework.
Each component peptide is verified individually by 3 independent U.S. laboratories before blending. After blending, the combined product is re-verified. Lot-specific COAs are publicly verifiable at smartmdpeptides.com/verify.
All blends 3-lab verified. Component-level and combined.
