The core muscle-research category. A GHRH analog + a GHRP produce more pulsatile GH together than alone — the classic CJC-1295 + Ipamorelin pairing. Tesamorelin and Sermorelin are alternative GHRH analogs. These are the most-studied compounds for GH-axis research.
A long-acting IGF-1 analog studied for growth signaling downstream of GH. It's an advanced compound and is usually not stacked casually with a full GH protocol — see the stacking guide.
Muscle research isn't only about growth signaling — durability matters. The BPC-157 + TB-500 healing pair is frequently combined with the GH stack (the four-part "Wolverine" combination) because the mechanisms don't overlap.
| Goal | Compounds |
|---|---|
| GH signaling | CJC-1295 + Ipamorelin, Tesamorelin, Sermorelin |
| Growth signaling | IGF-1 LR3 (advanced) |
| Recovery / durability | BPC-157, TB-500, GHK-Cu |
All of these are tracked on PepsTracker across 26 vendors, normalized to cost-per-mg with codes applied. Platinum Peptides carries the full range (incl. CJC/IPA and TESA/IPA blends), 15% off with pepstracker15.
The main category is growth-hormone secretagogues — GHRH analogs (CJC-1295, Tesamorelin, Sermorelin) paired with a GHRP (Ipamorelin) — plus IGF-1 LR3 for growth signaling. Healing peptides (BPC-157, TB-500) support recovery. All are research use only.
Yes. The GH stack (CJC-1295 + Ipamorelin) and healing stack (BPC-157 + TB-500) act on different mechanisms, so the four-part combination is a common advanced recovery approach.
PepsTracker normalizes every compound to cost-per-milligram after discount codes across 26 vendors, so you can compare GH secretagogues, IGF-1 LR3 and recovery peptides on the same basis.
