What is the main difference between Follistatin and LL-37 Truncated Variants (KR-12 / KS-30)?

Follistatin is primarily classified as a performance compound (muscle builder.). LL-37 Truncated Variants (KR-12 / KS-30) is a recovery compound (shorter active fragments of ll-37 (kr-12, ks-30) with retained antimicrobial activity but lower toxicity.).

Can Follistatin and LL-37 Truncated Variants (KR-12 / KS-30) be stacked together?

Some peptide pairs in different categories (e.g., recovery + cognitive) are commonly stacked. Others overlap mechanistically and shouldn't be combined. Always consult a licensed physician before stacking compounds.
