Cedric Preston, RD, CPT
Senior Nutrition & Supplementation Specialist | HL Supps
US-trained registered dietitian and certified personal trainer. Translates published research into supplementation protocols that actually work in the gym — and tells you when the evidence isn't there yet.
Background
Cedric is a registered dietitian. He earned his degree at California University, United States, in 2005, and has been working with athletes on the floor and through the kitchen ever since.
His coaching practice runs on two tracks. On one side, individualized nutrition and supplementation programming for 200+ long-term clients — intermediate lifters chasing their first 200 kg deadlift, physique athletes in contest prep, masters lifters trying to keep training intensity high without breaking down. On the other, weekly personal training shifts at gyms, where the work is hands-on, set-by-set, and grounded in what the client's body actually does that day — not what the spreadsheet predicted.
He treats both lanes as one job: read the client, read the literature, build the protocol, measure the response, adjust.
What he covers at HL Supps
Cedric's content sits in the "informed athlete" lane — the reader who already knows what BCAAs are and now wants to understand whether turkesterone has any human RCT data behind it, or which DMHA pre-workout fits a powerlifter's CNS load on heavy-squat day.
His coverage areas across the five HL Supps pillars:
- Pre-workout pharmacology — caffeine, DMHA, Eria Jarensis, geranium, stimulant cycling and CNS tolerance protocols
- Testosterone & PCT — natural test boosters (fadogia, tongkat ali), post-cycle recovery, bloodwork-driven decisions
- Mass & natural anabolics — turkesterone, ecdysterone, laxogenin: what the human evidence actually supports, and what's still rodent-only
- Cycle support — TUDCA, NAC, milk thistle, berberine — why every advanced cycle needs a liver and lipid protocol
- Performance nutrition — protein timing, calorie partitioning, recomposition, athlete sleep nutrition
Approach to content
Three rules guide everything Cedric publishes here.
Evidence first. No claim without a citation. If the data is rodent-only, it gets labelled rodent-only. If a meta-analysis says the effect is real but small, that's how it gets reported. Hype is for ad copy — not for content with someone's training cycle on the line.
Bloodwork over guesswork. Especially on testosterone, fat-loss stims, and any cycle protocol. The body tells you what's happening — total T, free T, lipid panel, LFTs, hematocrit. Measure, don't assume.
Risk awareness over hype. Strong compounds work strongly in both directions. Cedric writes contraindications as carefully as he writes dosing — because a reader skipping the contraindication paragraph is exactly who needs to read it.
Every YMYL-classified article published under his name is reviewed by our pharmacological reviewer, Allisa Connor, PhD, before going live. That isn't a formality — it's the standard for the content HL Supps puts on the record.
Personal
Cedric trains six days a week. Strength work is his default — heavy compound lifts, conjugate-style accessory programming, and enough volume to know what a real recovery deficit feels like by Friday.
On rest days he's on the trails. MTB is his decompressor — long enduro rides through forest singletrack, the kind of off-day work that reminds him why VO₂ max matters even for athletes who never compete in cardio sports.
He doesn't write about supplements he wouldn't run himself. If something is in the catalog and he won't take it, he'll tell you why in the article.
