PREMIUM SUPPLEMENTS.
IN-HOUSE.
Expert-curated, staff-advised, zero counterfeits. Everything you need to fuel your training is already at 515 Watertown Ave.
WHY BUY IN-GYM
Shopping supplements online is a gamble. Buying from us is not.
Expert-Curated Selection
Every product in our shop went through a vetting process. Our staff tried it, researched it, and approved it before it hit the shelf. No filler brands, no mystery ingredients.
No Counterfeit Products
Online marketplaces are flooded with knockoffs and under-dosed garbage. When you buy from our shop, you get the real product with a verified supply chain. Your health isn't a gamble.
Staff Can Advise You
Walk in and ask a question. Our coaches and staff know this stuff. Get real guidance on what to stack, what to avoid, and how to use what you buy — not a product description page.
Convenient Pickup
Already coming to train? Add your supplements to the pickup without a second trip or waiting for shipping. It's already here. You're already here. Take it home.
SUPPLEMENT CATEGORIES
We stock what works across every major performance category. Ask staff for current availability.
Protein & Mass Gainers
Whey isolates, concentrates, casein, plant-based blends, and mass gainers for serious muscle-building goals. Hit your protein targets without destroying your appetite or your wallet.
Inquire →Pre-Workout & Energy
Stimulant and non-stimulant pre-workouts, nootropic blends, and clean energy formulas. Find what locks you in before training without the crash that wrecks the rest of your day.
Inquire →Vitamins & Minerals
Multivitamins, vitamin D, magnesium, zinc, omega-3s, and targeted micronutrient support. Close the gaps in your diet and keep your hormones, immune function, and joints running right.
Inquire →Recovery & BCAAs
Branched-chain amino acids, EAAs, creatine, electrolyte blends, and sleep-support formulas. Build your recovery stack so you can train hard today and show up ready tomorrow.
Inquire →WE ONLY CARRY WHAT WORKS
This isn't a supplement store that stocks whatever has the best margin. We're a gym first — which means every product on our shelf has been evaluated through the lens of performance, not profit.
Our staff personally uses and tests what we carry. If it doesn't meet the standard, it doesn't make the cut. That's the only policy we have.
- Staff-tested products — our coaches use what they recommend
- Label transparency — no proprietary blends hiding under-dosed ingredients
- Third-party verified — brands that meet testing standards
- Continuously updated — we cut products that stop meeting the bar
