Medical Uses of Peptides
I cannot provide specific medical guidance about peptides sold on commercial websites, as the evidence provided focuses exclusively on natriuretic peptides (BNP/NT-proBNP) used as cardiac biomarkers for heart failure diagnosis, not therapeutic peptides sold commercially 1.
What the Evidence Actually Covers
The provided guidelines and research discuss:
Natriuretic Peptides as Diagnostic Biomarkers
- BNP and NT-proBNP are cardiac stress markers, not therapeutic agents—they are measured in blood to diagnose and exclude heart failure 1
- These peptides are secreted by the heart in response to volume/pressure overload and serve as semi-quantitative markers of cardiac dysfunction 1
- Diagnostic thresholds for acute heart failure: BNP >100 pg/mL or NT-proBNP >450 pg/mL (age <50), >900 pg/mL (age 50-75), >1,800 pg/mL (age >75) 1
- Exclusion thresholds: BNP <35 pg/mL or NT-proBNP <125 pg/mL effectively rule out chronic heart failure 1
Therapeutic Peptides in General Medicine
The research evidence discusses peptide drugs broadly:
- Over 80 peptide-based drugs are FDA-approved for conditions including diabetes (insulin), cardiovascular disease, and urological disorders 2
- Approximately 140 peptide therapeutics are in clinical trials for various medical conditions 3
- Peptides function as hormones, enzymes, signaling molecules, and targeted drug delivery systems 4, 5
- Cosmetic peptides are used in skin care products for anti-aging and skin health purposes 2
Critical Caveats About Commercial Peptide Products
Without knowing the specific peptides on the website in question, I cannot provide medical guidance on their uses. The evidence provided does not address:
- Growth hormone secretagogues
- Melanotan peptides
- BPC-157 or TB-500
- Thymosin peptides
- Other research or "gray market" peptides
Any peptides sold outside FDA-approved pharmaceutical channels should be approached with extreme caution, as they may lack quality control, proper dosing information, or evidence of safety and efficacy 6.
