300mg Epicatechins at a Solid Dose, Straight-Up Capsules
Blackstone Labs Epi Cat is a straightforward capsule product focused on one main goal: hitting you with a solid dose of epicatechins to boost blood flow, improve your workouts, and maybe give a muscle-building edge, all without a bunch of extra junk on the label. It's not some everything-but-the-kitchen-sink muscle booster. It's a no-nonsense epicatechin setup with green tea extract as backup, perfect for people who get that simpler can be better when the key stuff is dosed right.
The star here is 300mg epicatechins. That's key because epicatechin is a polyphenol — a natural compound from plants — that's got real research on improving blood vessels in sports nutrition. It works by boosting nitric oxide through something called eNOS (endothelial nitric oxide synthase) and keeping NO around longer, which helps widen blood vessels and improve flow. In the gym, that means more oxygen and nutrients hitting your muscles, leading to better pumps. It's also looked at for building more mitochondria — the powerhouses in cells — and better insulin sensitivity, which help with performance and how your body uses food. For bodybuilders, the cool part is its potential with follistatin and myostatin — proteins that affect muscle growth. That's why it's called a 'myostatin support' ingredient. Truth is, the idea is interesting, but real human results for big muscle gains are still up in the air. It shines most for blood flow and vessel health; the pure muscle-building stuff is still developing.
The dose is a big win here. Studies often talk about 200–300mg as effective, and Epi Cat gives you the full 300mg — that's the high end, making it way better than products that just add a tiny bit for show. You should not expe

Key Highlights
- 300mg Epicatechins — this is the main event and the key number to check. Studies point to 200–300mg as the sweet spot, so Epi Cat nails the top of that range instead of just tossing in a pinch for the label.
- Epicatechin boosts nitric oxide via eNOS activity and keeping NO available. That leads to wider blood vessels, better flow, and the fuller, more vascular feel during workouts that you're really after.
- Strong evidence for blood flow and pressure support makes epicatechin legit. Even if the muscle gains are still being figured out, its vascular benefits beat out a lot of stuff in this category.
- Myostatin appeal without the hype. Epicatechin gets studied for shifting follistatin-to-myostatin ratios, which is why lifters grab it, but this keeps it real with a dose that's actually meaningful.
- 700mg Green Tea extract brings in a second boost. It adds more catechins — active compounds in tea — and helps with body comp, making this great for cutting or recomp.
- Just two ingredients, both fully listed. No hidden blends here, so you can check every milligram against what you've read instead of guessing.
- Capsules make it easy to stay consistent. If you're tired of powders and shakers, this two-cap serving is simple to pop daily.
- Light on stims for more flexibility. Green tea can give a bit of energy, but it's not loaded with caffeine, so it pairs well with other stuff or later workouts.

Who Is This For?
- Bodybuilders in a growth phase wanting more than just energy. The 300mg epicatechins is why you buy this — a good dose for nitric oxide, flow, and that full muscle chase.
- Lifters cutting or recomping who need body comp help without heavy fat burners. 700mg green tea adds metabolism and catechins, while epicatechins keeps pumps strong when calories drop.
- Mid-level gym rats with creatine and protein covered, looking for a simple capsule add-on for lean muscle. It's targeted, not a bloated everything product.
- Late-day trainers needing lighter stims than typical pre-workouts. Not zero caffeine, but way milder, easier for evenings if you're sensitive.
- Pump chasers focused on flow and fullness without another powder. Epicatechin's nitric oxide support gives real vascular help, especially with citrulline.
- Folks curious about myostatin and follistatin but wanting straight talk. This has the key ingredient at a solid dose, without overhyping the science.
How to Use
Take 2 capsules with 8–12 ounces of water about 30–45 minutes before lifting. That gives time for it to kick in before heavy sets. If you're super sensitive to stims, try 1 cap first since green tea can add energy even without listed caffeine. Okay with a light meal if your stomach acts up, but heavy food might slow it. On rest days, many keep the full dose for routine, especially in a body-comp plan. Stacks well with creatine and citrulline pumps. Don't pile on tons of thermogenics or high-caffeine stuff until you test it. Keep the bottle cool and dry, away from heat. No need for strict cycling like heavy stim products, but breaks are smart if mixing caffeinated things.
What to Expect
First 0–15 minutes are chill since it's capsules and low-stim. By 20–45 minutes, some feel a light lift from green tea, but the real deal is in the workout: better veins, fuller muscles, cleaner pumps. Mid-session, it's subtle but helpful, not over-the-top. No big crash from this alone, but watch if stacking stims. Days 1–7 keep it low-key and tied to training. Weeks 2–4 is where it clicks with consistent workouts — steadier pumps, better sessions, fitting lean or cut goals.

Frequently Asked Questions
How much epicatechins is in Blackstone Labs Epi Cat?
Each full 2-capsule serving provides 300mg epicatechins. That is the key active in the formula and aligns with the 200–300mg range commonly referenced for epicatechin research and performance-focused use.
What does the 700mg green tea extract do in Epi Cat?
The 700mg green tea extract gives Epi Cat a secondary body-composition angle. It complements epicatechins by adding catechin-rich metabolic support and a mild low-stim energy component, making the product more useful during cutting and recomposition phases.
Is Epi Cat a myostatin inhibitor?
Epi Cat is marketed in that conversation because epicatechin is studied for its potential influence on the follistatin-to-myostatin ratio. The honest answer is that the mechanism is interesting and the ingredient is legitimate, but human evidence for dramatic direct myostatin inhibition and muscle gain remains mixed rather than definitive.
Is Blackstone Labs Epi Cat a stimulant product?
It is best described as low-stim, not stimulant-free. The formula contains green tea extract, which can contribute naturally occurring caffeine, but total caffeine is not disclosed and this is not built like a traditional high-stim pre-workout.
When should I take Epi Cat?
Most users do best with 2 capsules taken 30–45 minutes before training with water. Some also use it daily, including rest days, when they want a consistent routine as part of a multi-week recomp or lean-gain stack.
Can I stack Epi Cat with a citrulline pump pre-workout?
Yes, that is one of the smartest ways to use it. Epicatechin supports nitric oxide signaling and vascular function, while L-citrulline increases arginine availability for NO production, creating a more complete blood-flow stack.
Will I feel Epi Cat right away?
Not like a heavy caffeine pre-workout. Most users notice more subtle effects such as improved vascularity, better pumps, and a cleaner training feel, with the formula making more sense over repeated workouts than from a single serving.
Is Epi Cat beginner-friendly?
Yes, in terms of complexity and stimulant load. It is only two active ingredients with transparent dosing, though beginners should still understand that this is a niche physique-support product, not a substitute for creatine, protein, calories, and training consistency.
Does Epi Cat need to be cycled?
There is no strict requirement to cycle epicatechin itself in the way users often cycle very aggressive stimulant products. If you are stacking Epi Cat with other caffeinated or thermogenic supplements, periodic breaks from the broader stack are still a good idea.
Is Epi Cat vegetarian?
No. The capsule uses gelatin, so it is not suitable for vegetarians or anyone avoiding animal-derived capsule shells.
