Shop Xtend supplements

XTEND is one of the best-known BCAA intra-workout brands — flavoured amino powders designed to sip during training for athletes who want hydration-style aminos without a full protein shake mid-session.

GymStack’s XTEND collection is BCAA-focused (30+ listings) with classics like Watermelon Explosion, Knockout Fruit Punch, Lemon Lime Squeeze, Strawberry Kiwi, Mango Madness and Italian Blood Orange in standard and larger tubs.

How to use XTEND: mix during workouts or long sessions when you want BCAAs and flavour without heavy calories; keep a separate protein shake for total daily protein. Prefer essentials over BCAAs? Compare EAAs. Also see BCAAs, intra-workout and amino acids.
