Olivia Parker - Home Gym Tester, Brooklyn NYC
Fitness influencer, ex-London, relocated to NYC for the home-gym scene. Results-driven testing only. No paid placements, ever.
Hi, I am Olivia.
I started building home gyms in 2021 when London lockdowns shut down every gym in the city. By the time I moved to NYC in 2024 for the heavier kettlebell culture, I had tested 60+ supplements and lost trust in 75% of them.
This site is the result of three years of work : a 12-step methodology, third-party HPLC results published openly, and a brutally honest 2026 shortlist. If a brand fails the methodology, it gets cut - even if it pays the best affiliate commission.

Why I built this site
In 2023 I bought a whey isolate from a popular DTC brand that ranked #1 on Google for "best whey protein USA". Third-party HPLC later showed it contained 18% less protein than the label claimed. I asked for my money back. They sent me a discount code instead.
That is when I started buying tubs at retail and sending samples to Eurofins. I started publishing the HPLC results on Instagram. By 2025 I had a small but obsessive audience asking for a one-stop shop.
This site is that shop. Every product passes the 12-step methodology. Every lab result is linked. Every commission is disclosed.
My testing routine
I run every product through a 30-day in-home trial in my Brooklyn home gym (24m2, four kettlebells from 16 to 32 kg, one barbell, one rower). I track:
- Recovery (HRV via Whoop band, morning resting HR).
- Performance (PRs on 5x5 squat, deadlift, bench, weekly).
- GI tolerance (1-10 scale, daily).
- Mixability (clumps / lumps / froth).
- Taste (1-10, after 30 days to avoid honeymoon bias).
Editorial standards
- All product purchased at retail. Zero free samples accepted.
- Affiliate links disclosed inline and on affiliate disclosure.
- HPLC results dated and re-tested annually.
- If a brand changes its formula, I re-test before the existing review stays up.
- Comments and corrections welcome via Instagram DM.
