Anastrozole / Exemestane (Aromatase Inhibitors) vs Collagen Peptides (+ Vitamin C)
Both are used for joint health. Here's how they compare on human evidence, mechanism, safety and availability — in plain English.
| Anastrozole / Exemestane (Aromatase Inhibitors) | Collagen Peptides (+ Vitamin C) | |
|---|---|---|
| Human evidence | ★★★★☆ | ★★★★☆ |
| Legal status | Prescription, Off-Label | OTC Supplement |
| How it works | Inhibit aromatase (CYP19A1), the enzyme converting testosterone to estradiol. Anastrozole is reversible; exemestane is a suicide (irreversible) inhibitor. | Hydrolysed collagen supplies glycine/proline/hydroxyproline that preferentially accumulate in tendon/ligament; taken with vitamin C (cofactor for prolyl hydroxylase) before loading, it doubles collagen-synthesis markers. |
| In plain English | High testosterone partly converts to estrogen, which can cause bloating and gyno. These drugs block that conversion. Easy to overdo — crashing estrogen wrecks mood, joints, and libido. | Feeds your tendons and ligaments their raw materials right before you stress them — timing matters, so take it ~45 min before training with vitamin C. |
| Bottom line | Use only if estradiol is genuinely high; low estrogen is as bad as high. | The most practical connective-tissue supplement; timing is key. Highly relevant to running/Hyrox tendon load. |
| Availability | Prescription only | Available over the counter |
Which is better for joint health?
Both carry a comparable human-evidence rating (★★★★☆). Choose on mechanism fit, side-effects, availability and cost rather than evidence strength alone — they work through different mechanisms.
