Zac Perna Supplement Stack UK: A Smarter Buyer's Guide for 2026

Zac Perna built his physique on EHPlabs: IsoPept Zero whey isolate, Creatine, BeyondBCAA EAAs and OxyShred for morning energy. EHPlabs ships from Australia with limited UK stock. Here are the UK alternatives that match each slot in his stack, in stock from UK warehouses with next-day delivery.

Zac Perna Supplement Stack UK: A Smarter Buyer's Guide for 2026

Quick answer

Do not import Zac Perna's full branded stack. The UK substitutes are cheaper and the least useful items can be removed entirely. Our version is Applied Nutrition ISO-XP only if you need isolate, generic creatine monohydrate at 3–5g daily, and ABE pre-workout only when caffeine genuinely improves the session. We would skip the BCAA/EAA product when daily protein is already sufficient and skip the thermogenic as a fat-loss shortcut. Copy the useful ingredients and doses, not the influencer's sponsor relationship.

01

What does Zac Perna take, and what should UK buyers actually buy?

Zac Perna's stated stack is EHPlabs IsoPept Zero (whey isolate), EHPlabs Creatine at 5g daily, EHPlabs BeyondBCAA, and EHPlabs OxyShred as a morning thermogenic. The closest UK alternatives are Applied Nutrition ISO-XP (matching IsoPept Zero on protein density and Informed Sport certification), MyProtein Impact Creatine (creatine monohydrate is creatine monohydrate, and the brand premium does not change the molecule), Applied Nutrition Amino Fuel EAA (the BeyondBCAA equivalent), and Applied Nutrition ABE Pre Workout (matching OxyShred's 200mg caffeine and adding clinical-dose beta-alanine plus citrulline). Total monthly cost runs around £55 to £65 from a UK warehouse versus £90 to £110 importing the EHPlabs originals.

02

What Zac Perna actually has in his stack

Zac has been an EHPlabs ambassador since 2022 and shares the discount code ZAC10 on EHPlabs purchases. Across his Instagram, YouTube, and EHPlabs ambassador page, four products recur in his content.

  1. 1

    EHPlabs IsoPept Zero: hydrolysed whey protein isolate at around 25g protein per 32g serve with negligible fat and sugar, the cleanest macros in the EHPlabs lineup.

  2. 2

    EHPlabs Creatine Monohydrate: 5g per serve, taken daily with no loading phase. Zac has stated creatine plus BCAAs were the supplements that helped him retain muscle through cuts.

  3. 3

    EHPlabs BeyondBCAA: branched-chain amino acids with electrolytes, taken during and after workouts. In his recent content this has shifted toward full essential amino acid (EAA) products for the broader amino spectrum.

  4. 4

    EHPlabs OxyShred: the thermogenic fat-burner he calls his morning kick-off, used for fasted cardio and early lifting sessions, combining caffeine with the standard thermogenic supporting cast (acetyl L-carnitine, green coffee, taurine).

What Zac Perna actually has in his stack continued

Two notes on framing are worth stating up front. First, this reflects what he has stated publicly, not something we observed directly. Second, no supplement made the physique; the training and the nutrition did. The stack supports the work rather than replacing it.

Community perspective

What others are saying

Pride by EHP labs - its the collab between EHP and Zac Perna :) It's honestly a great pre I've been using it for a while now.

Why this is a UK alternative guide, not an EHPlabs import guide

EHPlabs has no UK warehouse and no major UK retailer carrying the full range. Buying direct from ehplabs.com to a UK address means dealing with all of the following.

  1. 1

    7 to 14 day shipping from the US or Australia warehouse

  2. 2

    £10 to £20 shipping cost per order

  3. 3

    A possible customs charge if the order plus shipping exceeds the £135 import threshold

  4. 4

    No reliable returns process for damaged or short-dated stock

Why this is a UK alternative guide continued

For four supplements bought monthly, that adds up to real friction. The UK shelf in 2026 has Informed Sport whey isolate at 90g protein per 100g (matching IsoPept Zero), Creapure and standard monohydrate creatine at a fraction of the EHPlabs price, EAA blends with the same amino spectrum as BeyondBCAA, and dose-precise pre-workouts that deliver the OxyShred caffeine hit alongside performance ingredients OxyShred does not include. Every recommendation below is in stock from a UK warehouse with next-day or 48-hour delivery.

06

Whey isolate slot: UK alternatives to IsoPept Zero

IsoPept Zero is a hydrolysed whey isolate at roughly 78g protein per 100g, under 1g sugar, under 1g fat, with added digestive enzymes. The UK isolate shelf has three picks that get you within touching distance on macros at a meaningfully lower cost per 25g of protein.

Applied Nutrition ISO-XP delivers 90g protein per 100g, under 1g fat, under 1g sugar, stays lactose-friendly, and carries Informed Sport certification for tested athletes. It beats IsoPept Zero on protein density and matches it closely on mouthfeel post-mix, and it is available across UK retailers including direct, Bulk, Amazon UK, and Holland and Barrett.

Bulk Pure Whey Isolate delivers 84g protein per 100g with a transparent label and the lowest cost per 25g of protein in the UK isolate tier. The 2.5kg bag in unflavoured or vanilla consistently sits under £1.30 per 25g of protein on Bulk's own site, undercutting almost every dedicated isolate on Amazon UK.

MyProtein Impact Whey Isolate delivers 76g protein per 100g, lower than ISO-XP or Bulk, but drops to under 90p per 25g of protein on Impact Week codes. The best approach is waiting for Impact Week, buying in bulk, and storing it dry, since off-sale it sits mid-pack on value.

07

Creatine slot: 5g daily, no brand premium needed

Creatine monohydrate is the most evidence-backed supplement in any lifter's stack and the one where brand premium delivers the least, since the molecule stays identical across brands. The standard protocol is 5g per day, every day, with no loading required for long-term saturation.

MyProtein Impact Creatine runs around 17p per 5g serve on the 1kg tub, dropping under 12p during Impact Week. The 250g and 500g tubs are convenient sizes for testing flavour before committing to a year's supply, and it delivers pure micronised creatine monohydrate with no fillers.

Holland and Barrett creatine monohydrate carries the widest UK retail availability of any creatine, sold in supermarkets, Holland and Barrett, Amazon UK, and dedicated gym shops. It costs more per gram than MyProtein but is useful if you want to grab a tub on the high street without waiting for delivery.

08

EAA slot: UK alternatives to BeyondBCAA

BeyondBCAA is a branched-chain amino acid blend with added electrolytes. Modern sports science has largely moved on from pure BCAAs to full essential amino acid (EAA) profiles, which include the leucine, isoleucine, and valine of BCAA plus the other six essentials your body needs for muscle protein synthesis. The two UK picks below are EAA blends rather than pure BCAAs.

Applied Nutrition Amino Fuel delivers 11g of essential amino acids per serve including 4g of leucine, with vitamin B6, vitamin C, and electrolytes. It is sold in 390g tubs around 25 to 30 serves, carries Informed Sport certification for tested athletes, and matches BeyondBCAA most closely on amino content while offering a broader amino spectrum.

MyProtein Amino Energy offers a simpler 8.5g EAA blend per serve with 4g of BCAAs in a 2:1:1 ratio. It costs less than Amino Fuel and comes in a wider flavour range, including limited-edition Robinsons and Sour Patch Kids collabs that the EHPlabs ranges do not match.

09

Morning energy slot: UK alternatives to OxyShred

OxyShred sits in the thermogenic fat-burner category, but its main job in Zac's stack is delivering a morning caffeine kick before fasted cardio and weights. A dose-precise pre-workout delivers that same hit alongside performance ingredients (beta-alanine, citrulline) that OxyShred does not include, at a comparable serving size.

Applied Nutrition ABE delivers 200mg caffeine, 3.2g beta-alanine, 6g citrulline malate, and 2g creatine monohydrate per scoop on a transparent label. The 375g Informed Sport version is the tested-athlete pick, and it matches OxyShred's caffeine at roughly half the cost per serve when bought from a UK warehouse.

Grenade .50 Calibre delivers 200mg caffeine per scoop alongside BCAAs, arginine, and beetroot extract, and consistently wins UK Trustpilot taste rankings. If ABE's flavour range does not click for you, this is the next step.

10

The full UK alternative stack: monthly cost

Running the four-slot stack monthly at typical training volumes (1 scoop isolate, 5g creatine, 1 scoop EAA, 1 scoop pre-workout per training day, 4 sessions per week) breaks down as follows.

  1. 1

    Whey isolate (Applied Nutrition ISO-XP, 1.8kg): around £45 per month at 1 scoop per training day plus 1 on rest days

  2. 2

    Creatine (MyProtein Impact Creatine, 1kg): around £4 per month at 5g per day

  3. 3

    EAA (Applied Nutrition Amino Fuel, 390g): around £8 per month at 1 scoop per training day

  4. 4

    Pre-workout (Applied Nutrition ABE, 315g): around £8 per month at 1 scoop per training day

11

The full UK alternative stack: monthly cost continued

Total UK alternative stack: approximately £55 to £65 per month. The equivalent EHPlabs stack imported to the UK runs £90 to £110 per month before any customs charge, meaning the same training and the same physique outcome for 30 to 50% less spend.

12

Where the UK alternatives do not quite match

Three honest caveats on the swap are worth stating, since the recommendations would not hold up to scrutiny without them.

  1. 1

    Hydrolysed vs standard isolate: IsoPept Zero is partially hydrolysed, meaning the protein has been pre-cleaved into shorter peptides for faster digestion. ISO-XP and Bulk Pure Whey Isolate are standard isolates. For most lifters the digestive difference is undetectable, though for intra-workout use or for people with whey sensitivity, the hydrolysed version sits marginally easier on the stomach.

  2. 2

    OxyShred is a thermogenic, not a pre-workout: the replacement here trades the fat-burner positioning for performance ingredients. If the thermogenic effect (acetyl L-carnitine, green coffee, garcinia) was load-bearing in your routine, the pre-workout swap will not replicate it, though the fat-loss evidence on those ingredients is weak in any case.

  3. 3

    EAA vs BCAA: modern research broadly supports full EAA blends over pure BCAA blends, but if you specifically liked BeyondBCAA's 2:1:1 BCAA ratio and the electrolyte hit, the closer match is Applied Nutrition BCAA Amino Hydrate rather than the Amino Fuel EAA.

Frequently asked questions

What supplements does Zac Perna take?+

Zac Perna is a long-running EHPlabs ambassador and his stated stack centres on EHPlabs IsoPept Zero whey isolate, EHPlabs Creatine at 5g daily, EHPlabs BeyondBCAA (he uses essential amino acids during and post-workout), and EHPlabs OxyShred as a morning thermogenic for early cardio and lifting sessions. He shares the discount code ZAC10 on EHPlabs purchases.

Where can I buy EHPlabs in the UK?+

EHPlabs ships to the UK from Australia and the US but does not have a UK warehouse or major UK retailer distribution. Orders typically take 7-14 days, carry international shipping fees, and can attract customs charges over the £135 import threshold. For UK buyers, equivalent Informed Sport-certified whey isolate, creatine monohydrate and EAAs are stocked next-day-delivery by Applied Nutrition, Optimum Nutrition, Bulk and MyProtein.

What is the UK alternative to EHPlabs IsoPept Zero?+

Applied Nutrition ISO-XP is the closest UK alternative to IsoPept Zero on macros - 90g protein per 100g, under 1g fat, under 1g sugar, Informed Sport certified, and lactose-friendly. Bulk Pure Whey Isolate at 84g per 100g is the value pick. MyProtein Impact Whey Isolate at 76g per 100g is the cheapest tier on Impact Week.

Is OxyShred available in the UK?+

OxyShred is sold in the UK through limited specialty retailers and EHPlabs direct, but with the same import lead time and shipping cost as the rest of the range. For the morning-energy slot in a Zac-style stack, Applied Nutrition ABE Pre Workout delivers comparable caffeine (200mg per serving) plus the beta-alanine and citrulline doses that OxyShred does not include, at roughly half the cost per serving when bought from a UK warehouse.

Does Zac Perna train fasted on OxyShred?+

Per his own content, Zac uses OxyShred first thing as the morning kick-off for fasted cardio and weights sessions. A UK alternative approach is a 200mg caffeine pre-workout (Applied Nutrition ABE or Grenade .50 Calibre) with 8oz of black coffee on rest days for tolerance management. The performance driver in his stack is the caffeine plus the EAAs intra-workout, not OxyShred specifically.
