❓ Frequently Asked Questions

Are peptides legal in my country?
Legality varies by region. Peptides sold for research purposes are generally legal, but human consumption may be restricted. Check local laws before purchase.
How do I know the purity is real?
Look for third-party COAs. Verified suppliers post batch-specific certificates confirming purity and composition.
Can beginners safely use peptides?
Peptides are research chemicals. Beginners should only use them in a lab/research context. Our recommendations focus on safe, verified purchasing.
How should peptides be stored?
Most peptides require refrigeration (2-8°C) or freezing (-20°C) and must be protected from light. Follow supplier instructions for stability.
Can peptides be combined in research protocols?
Yes, but only according to verified research protocols. Combining peptides like BPC-157 + TB-500 is common in tissue repair studies.
