SAC StudioThe cheapest per capsule — and unlike most value bottles, it discloses a potency figure.
Double Wood Cordyceps is the budget champion. At roughly $20 for 210 capsules — about a 3.5-month supply at the two-capsule serving — nothing on the list is cheaper per capsule, and unlike most rock-bottom-priced bottles it does two things right: it discloses a potency figure (7% polysaccharides) and it emphasises third-party testing plus a money-back guarantee.
The honest limits are why it sits at #8. That 7% is total polysaccharides — alpha plus beta glucans — not a clean beta-glucan number, so it's a softer spec than Real Mushrooms' >8% beta-glucans or FreshCap's 32%; you don't know how much of the 7% is the active beta-glucan fraction. And while the label states an entire fruiting body extract — a genuine plus, since it's not a mycelium-on-grain filler — it never prints a species name, so you can't confirm it's the cordycepin-richer militaris type the way the explicitly-militaris picks let you. For the lowest cost-per-day with at least some disclosed transparency, though, it's the clear value pick. Here's the breakdown.
The label states 'Entire Fruiting body' — a genuine plus, since it's not a mycelium-on-grain filler, and it matches the extract form the top-ranked militaris picks use. But the Supplement Facts panel, back label, and side label never print a species name, so we can't confirm this is the cordycepin-richer militaris type the way #1-#3 explicitly are. Scored at the site's disclosure floor for an unstated species: credit for a clean fruiting-body extract, capped below the verified-militaris picks because the species itself is unverifiable.
Discloses 7% polysaccharides — a stated figure, which is genuinely more than the value picks that disclose nothing — but it's TOTAL polysaccharides (alpha + beta), not a clean beta-glucan number, so you can't tell how much is the active fraction. Credited for disclosing something meaningful, but a softer spec than a stated beta-glucan percentage.
Emphasises third-party testing and backs the product with a money-back guarantee — a reasonable trust story for a budget brand, and more transparency than most value cordyceps. Solid for the price, held below the organic-certified and COA-publishing picks.
The cheapest cost-per-capsule on the list: ~$20 for 210 capsules, about $0.19 a serving and roughly a 3.5-month supply. Combined with a disclosed potency figure, that's standout value — the lowest cost-per-day with at least some transparency. The product's strongest axis.
Species isn't stated on the label, so the evidence here is general rather than trial-matched: Chen 2010 found a standardised sinensis extract (CS-4) improved sub-maximal thresholds but not VO2max over 12 weeks, while Hirsch 2017 found a stronger signal on a confirmed-militaris blend. A plausible modest support over weeks either way, capped by limited, mixed evidence and an unverified species. The cheap, long supply at least makes a consistent multi-week run easy.
“Standardised to 7% polysaccharides.”
The 7% figure is disclosed and is more than most value cordyceps offer — but it's TOTAL polysaccharides (alpha + beta glucans), not the clean beta-glucan number that actually indicates active content. Honest as a disclosed spec; partial because a total-polysaccharide figure overstates how much you know about the active beta-glucan fraction.
“Third-party tested with a money-back guarantee.”
Consistent with Double Wood's stated practice. Third-party testing plus a money-back guarantee is a reasonable trust story for a budget brand and more transparency than most value cordyceps provide.
“210 capsules — best value cost-per-capsule.”
Supported: 210 capsules for ~$20 is the cheapest cost-per-capsule on the list, about a 3.5-month supply at the two-capsule serving. The value claim is accurate and is the core reason to choose it.
“Supports energy, endurance, and stamina (per the Amazon listing).”
This wording comes from the product listing, not the printed label — the only structure/function claim actually on the bottle is 'Supports Cardiovascular Health.' Species isn't stated on the label, and the general human data on cordyceps and exercise is mixed (Chen 2010 — sub-maximal threshold gains on a sinensis extract, no VO2max change; mechanism coherent per Tuli 2014, Hsu 2020). Honest as a modest 'supports' over weeks, overstated as a guaranteed endurance effect.
“Supports Cardiovascular Health.”
This is the structure/function claim actually printed on the product's front and side panels — the one marketing claim we can confirm directly from the label itself.
An earlier version of this review said Double Wood Cordyceps is 'a Cordyceps sinensis extract that blends fruiting body and mycelium' and scored Species & extract quality at 6.8/10 partly on that basis. The Supplement Facts panel and the physical back label both read 'Cordyceps Mushroom Extract 7% polysaccharides 1000mg — Entire Fruiting body,' with no mycelium listed as an ingredient and no species name printed anywhere on the label. We re-read the label on Sep 3, 2026 and revised every 'blends fruiting body and mycelium' and 'Cordyceps sinensis' reference to match: the product is an entire-fruiting-body extract, and its species is not stated on the label. Species & extract quality moved from 6.8 to 6.5 to reflect the disclosed fruiting-body form weighed against the undisclosed species; the overall score moved from 7.4 to 7.3.
Double Wood's value case is genuinely strong: ~$20 for 210 capsules, about $0.19 a serving and a 3.5-month supply, is the cheapest cost-per-capsule on the list. What separates it from rock-bottom bottles that state nothing is that it discloses a 7% polysaccharide figure and emphasises third-party testing plus a money-back guarantee. For a value buyer, that combination of lowest price and some transparency is exactly the point.
The honest caveat on the headline figure: 7% is TOTAL polysaccharides, alpha plus beta glucans, and only the beta-glucans are the active fraction — alpha-glucans are largely starch-like and can come from the substrate. So you can't tell how much of that 7% is actually doing anything, which makes it less informative than Real Mushrooms' clean >8% beta-glucans or FreshCap's 32%. It's more disclosure than nothing, but it's a soft number, which is why the claim is rated partial.
The label states 'Entire Fruiting body,' not a mycelium blend — a real point in its favour over raw mycelium-on-grain fillers. But it never names a species, so we can't confirm whether it's the cordycepin-richer militaris type or the more commonly used sinensis type; general Cordyceps research shows sinensis carries less cordycepin than militaris (Tuli 2014). Until Double Wood discloses a species, it stays in the value tier, below the explicitly-militaris extracts whose active content is verified.
Because the label doesn't state a species, the realistic expectation should be read as general cordyceps evidence rather than trial-matched: Chen 2010 found a sinensis extract (CS-4) improved sub-maximal exercise thresholds but not VO2max, and the overall human evidence is limited and mixed regardless of species. The upside is practical — the cheap, 3.5-month supply makes it genuinely easy and affordable to run cordyceps consistently for the weeks the evidence calls for. Take it daily, pair it with training, and treat any improvement as a welcome bonus.
Double Wood Cordyceps is the pick when your priority is the lowest cost-per-capsule, and it earns that title without being a black box. At roughly $20 for 210 capsules — about a 3.5-month supply — nothing here is cheaper per capsule, and unlike most value bottles it discloses a potency figure (7% polysaccharides) and emphasises third-party testing plus a money-back guarantee. That combination of price and transparency is the whole value case. It ranks #8 because of the softness of that spec and the unverified species. The 7% is total polysaccharides, not a clean beta-glucan number, so it's less informative than Real Mushrooms' >8% or FreshCap's 32%; and while the label states an entire fruiting body extract (a real plus over a mycelium filler), it never names a species, so we can't confirm cordycepin-relevant potency the way the explicitly-militaris picks let you. The general human exercise data on cordyceps is modest and mixed regardless of species (Chen 2010 — sub-maximal gains on a sinensis extract, no VO2max change). So consider Double Wood if you want the cheapest way to run cordyceps with at least some disclosed spec; choose a militaris fruiting-body extract (Real Mushrooms #1, FreshCap #2, Nootropics Depot #3) if you want verified, species-confirmed, cordycepin-relevant active content.

The other high-count value pick — 90 made-with-organic servings per bottle. Cheaper certification story, but unlike Double Wood it discloses no potency figure at all.
See it on the list →The overall winner — 100% militaris fruiting body with a clean, third-party-verified >8% beta-glucan figure (not a total-polysaccharide number). Buy this if you want verified, cordycepin-relevant active content.
See it on the list →A trusted CS-4 sinensis value option with reliable in-house GMP testing and flexible single-capsule dosing. Fewer servings per dollar than Double Wood, but a strong mainstream brand.
See it on the list →20 healthy older adults, 12 weeks: CS-4 (Cordyceps sinensis) improved metabolic and ventilatory thresholds versus no change on placebo — but VO2max did NOT change. Cited as general reference evidence for sinensis-type extracts; Double Wood's own label does not state a species, so this trial cannot be confirmed as directly matching this product. Evidence is for sub-maximal exercise economy, not peak aerobic power.
Cited as the contrast: a Cordyceps militaris blend improved VO2max and time-to-exhaustion after 3 weeks. The stronger endurance signal is documented for confirmed-militaris extracts; Double Wood's label does not state which species it uses.
Review of cordycepin, the principal bioactive of Cordyceps militaris. Explains why sinensis (which carries little cordycepin) ranks below a militaris fruiting body on active content, and why beta-glucans — not total polysaccharides — are the meaningful active fraction.
