The Most In-Demand Longevity Stack is Back: Klotho & Follistatin

If you're serious about aging well, these two deserve your attention. Klotho for deep cellular protection and whole-body anti-aging support — and Follistatin for building and preserving the lean muscle that keeps you strong, metabolically healthy, and independent as you age. Because longevity isn't just about living longer — it's about staying strong while you do it.

KLOTHO — The Longevity Protein

Klotho is a protein your body naturally produces, primarily in the kidneys. As we age, levels decline — and that decline is linked to accelerated aging across nearly every system in the body.

BioLongevity Labs' version (α-Klotho LR) uses patented albumin-binding technology to extend the half-life to up to 19 days. Just 10mcg subcutaneously every two weeks. No cycling needed. And it doesn't suppress your body's own production — it may actually help restore it.

Key highlights:

▸ Antioxidant defense — activates Nrf2 and FoxO pathways

▸ Cardiovascular support — nitric oxide signaling + fights vascular calcification

▸ Brain health — supports synaptic plasticity and neuronal protection

▸ Anti-inflammatory — inhibits NF-κB ▸ Metabolic support — improves insulin secretion, glucose and lipid metabolism

▸ Kidney, liver & lung protection — modulates TGF-β signaling

FOLLISTATIN (FLGR242) — The Muscle Builder

Follistatin inhibits myostatin — the protein that limits muscle growth. BioLongevity Labs re-engineered it to selectively target myostatin without affecting activin, and extended the half-life to 19 days using the same albumin-binding tech as Klotho.

Key highlights:

▸ Myostatin inhibition — without unwanted activin binding

▸ Muscle growth — increases fiber size and activates satellite cells

▸ Fat metabolism — promotes browning of white fat tissue

▸ Glucose metabolism — improves glucose uptake and reduces hepatic output

▸ Muscle preservation — especially relevant for GLP-1 users concerned about lean tissue loss

▸ Extended bioavailability — half-life from ~1-2 hours to up to 19 days

WHY PEOPLE ARE STACKING THEM

Klotho protects and optimizes at the cellular level. Follistatin builds and preserves the lean muscle that keeps you strong. Together, they cover two of the biggest pillars of aging well.
