Recommended dosage: 450–900 mg per week, typically injected 1–2 times weekly. Due to the high concentration, it's best suited for users with prior testosterone cycle experience. Hexyl 450 can be part of a standalone cycle or combined with compounds like Boldaxyl or Anadroxyl for maximum size and strength results.

Hexyl 450 includes a higher total concentration and a different ester ratio compared to Sustanon, offering both faster and longer-lasting testosterone release in a single product.

Most users report noticeable strength and size increases within 2–3 weeks, with optimal results after 6–8 weeks of consistent training, diet, and administration.
