What Sets These Compounds Apart
Six peptides that account for 80% of orders. Here’s why researchers keep coming back.
BPC-157
Gastric pentadecapeptide. Stable in stomach acid — unlike most peptides. Published in over 100 preclinical studies since 1991. 10mg lyophilized.
CJC-1295 / Ipamorelin
Two mechanisms, one vial. CJC extends the GH pulse window while Ipamorelin triggers release without touching cortisol or prolactin. 5mg/5mg blend.
Epithalon
Four amino acids. Activates telomerase in human cell cultures (Khavinson, 2003). One of the few peptides with published data on chromosome-level aging markers. 10mg.
Sermorelin
FDA-approved analog of GHRH(1-29). The cleanest growth hormone release profile in the secretagogue class — no appetite spike, no cortisol dump. 5mg.
TB-500
Full-length thymosin beta-4. Upregulates actin polymerization at wound margins. Frequently stacked with BPC-157 in published tissue repair protocols. 10mg.
PT-141
Bremelanotide. Works through MC3R/MC4R in the hypothalamus — not blood flow. The only peptide in its class that targets the CNS directly. 10mg.
The Standard We Hold Ourselves To
Independent Verification. Every Run.
HPLC purity analysis and ESI-MS molecular weight verification from an independent lab. Not in-house testing. Not “upon request.” Every production run, every time. The COA ships with your order.
99%+ or It Doesn’t Ship
A batch that tests at 98.7% gets destroyed. Not discounted. Not sold to a different vendor. Destroyed. Half a percentage point of impurity can introduce confounding variables that invalidate months of work.
From Synthesis to Your Freezer
Solid-phase peptide synthesis, proper lyophilization, and cold-chain storage from production to shipment. Peptides degrade at room temperature — how they’re stored matters as much as how they’re made.
Stop Guessing About Purity.
Every compound in our catalog ships with independent lab verification. That’s not a selling point — it’s the minimum.
All compounds sold by PreWorkout Formula are strictly for in-vitro research and laboratory use only. Not for human consumption. Not for veterinary use. No exceptions.
