BPC-157
RepairBody Protective Compound-157 (BPC-157) is a synthetic pentadecapeptide derived from gastric proteins that has demonstrated notable reparative and anti-inflammatory properties across diverse …
Semaglutide
MetabolicGlucagon-like peptide-1 (GLP-1) receptor agonists are widely used for the management of obesity; however, respiratory complications are rarely documented. A 40-year-old person without diabet…
CJC-1295
GH SecretagogueThe pursuit of pharmacological enhancement in sport has evolved from the widespread use of anabolic-androgenic steroids (AAS) to novel agents such as peptides and peptide analogues. Marketed…
Epitalon
LongevityEpitalon, a naturally occurring tetrapeptide, is known for its anti-aging effects on mammalian cells. This happens through the induction of telomerase enzyme activity, resulting in the exten…
Semax
NeuroAlzheimer's disease, first described over a century ago, is currently among the most common neurodegenerative diseases whose significance is increasingly growing with the aging of population…
Tirzepatide
MetabolicINTRODUCTION: Tirzepatide has been associated with significant reductions in body weight in randomized clinical trials. However, real-world evidence evaluating the multisystemic effects of t…

VK2735 vs Semaglutide (2026): Phase 3 Dual GLP-1/GIP Agonist vs the GLP-1 Benchmark
VK2735 showed up to 14.7% weight loss at 13 weeks in Phase 2; semaglutide showed 14.9% at 68 weeks in STEP 1. See how mechanisms, dosing and status compare.

5-Amino-1MQ vs Tesofensine: Oral, Non-GLP-1 Metabolic Research Compounds Compared
5-Amino-1MQ inhibits the NNMT enzyme in rodent studies; Tesofensine reached Phase 2 human trials as a triple monoamine reuptake inhibitor for weight loss.

CJC-1295 with DAC vs Ipamorelin: Half-Life, Receptors & GH Release Compared
CJC-1295 with DAC runs a 6-8 day half-life against Ipamorelin's 2 hours. Compare the two receptor pathways, GH release patterns and 503A review status.

Tesofensine vs Semaglutide: Oral Monoamine vs GLP-1 Mechanisms Compared
Tesofensine blocks 3 monoamine transporters orally; semaglutide agonises the GLP-1 receptor. Compare mechanism, half-life, and Phase 2 vs Phase 3 evidence.

WADA 2026 Prohibited List: Peptide Classification Guide for Researchers
WADA's 2026 Prohibited List groups peptides by mechanism, not name: see why ipamorelin, MOTS-c, and GLP-1 agonists fall into 3 distinct compliance categories.

Melanotan I vs Melanotan II: Comparing Two Melanocortin Receptor Agonists in Research
Melanotan I is MC1R-selective, chemically tied to afamelanotide; Melanotan II hits MC1R/MC3R/MC4R and gave rise to bremelanotide. See how mechanisms differ.
