TB-500 is a research compound. It is not approved by the FDA or any regulatory body for human use. This article is for educational and informational purposes only. Nothing here constitutes medical advice. Consult a qualified physician before considering any peptide use.
TB-500 is available as a research compound from several vetted suppliers. When sourcing TB-500, prioritize vendors with third-party certificates of analysis (COA), HPLC purity testing above 98%, and proper cold-chain shipping.
Where Can You Buy TB-500?
TB-500 is not fda-approved. available as a research chemical. banned by wada in athletic competition. It is available from several research chemical suppliers. The quality difference between vendors is significant — sourcing from a tested, reputable supplier is the single most important decision.
What Should You Look For in a TB-500 Vendor?
Third-party COA testing: Every batch should come with a Certificate of Analysis from an independent lab confirming identity and purity (98%+ HPLC).
Cold-chain shipping: Peptides degrade in heat. Quality vendors use insulated packaging and cold packs.
Proper packaging: Lyophilized powder in sealed, labeled vials. Avoid pre-mixed or pre-loaded products.
Reputation: Established vendors with consistent community feedback are safer than new or untested sources.
Which Vendors Carry TB-500?
WolveStack has reviewed the following suppliers for purity, COA availability, shipping practices, and community reputation. These are the vendors we recommend for sourcing research-grade TB-500.
What Red Flags Should You Watch For?
No COA: If a vendor can't provide a current, third-party COA for their TB-500, move on. This is non-negotiable.
Unusually low prices: Peptide synthesis is expensive. Prices dramatically below market average usually indicate underdosed or substituted product.
Pre-mixed solutions: Reconstituted peptides have a shelf life of 4-6 weeks. Vendors selling pre-mixed TB-500 in syringes or vials are shipping degraded product.
No contact/return policy: Legitimate vendors stand behind their products.
How Should You Store TB-500 After Purchase?
Unreconstituted TB-500 (lyophilized powder): Store at -20°C (freezer) for up to 12+ months. Keep sealed and away from moisture.
Reconstituted TB-500: Store at 2-8°C (refrigerator). Use within 4-6 weeks. Never freeze reconstituted peptides.
Bottom Line on Buying TB-500
Source TB-500 from vendors with current third-party COA testing, cold-chain shipping, and established reputations. Quality directly determines results — cheap peptides are expensive mistakes.
