Straight-up post-cycle support with arimistane leading the way.
Blackstone Labs PCT V is a no-stim hormone support formula that's all about simple post-cycle help: keep estrogen in check, balance your androgens, throw in some antioxidants, and add ingredients you see in a lot of recovery stacks for athletes. It's not a full health overhaul or a replacement for real PCT meds. It's a straight-up capsule supplement with full doses listed, mixing one key aromatase compound with backups to steady your hormones after a suppressive run.
The star is Androst 3,5-Dien-7,17-Dione at 37.5mg, known as arimistane in the supp world. It works by blocking the aromatase enzyme, which cuts down how much of your androgens turn into estrogen. Basically, it's the main player for why this is called a PCT product. That 37.5mg is a solid amount you see in OTC options, and it's what drives most of the benefits here.
You've got 250mg of Tribulus terrestris, standardized for saponins. Tribulus is super common in hormone supps, but let's be real: it's better for boosting your drive and libido than jacking up test levels in trained guys. 250mg isn't huge compared to solo trib products, but the standardization is key since saponins are what really matter. You'll probably feel this more in your energy and mood than in big muscle gains.
Saw Palmetto berry extract at 160mg brings in androgen balance. It's a go-to for dealing with 5-alpha-reductase and DHT stuff, making the formula more well-rounded than just an estrogen blocker.

Key Highlights
- 37.5mg Androst 3,5-Dien-7,17-Dione — the big gun for post-cycle vibes. It helps manage estrogen by hitting aromatase, perfect if you're after OTC support without the fluff.
- 250mg Tribulus terrestris standardized for saponins — way better than plain herb. Those saponins are why it's in here for that classic boost in drive and libido.
- 160mg Saw Palmetto berry extract — solid for keeping androgens in check. It targets 5-alpha-reductase and DHT, so you get more than just estrogen control.
- 125mg N-Acetyl Cysteine — throws in some glutathione-building power. NAC is great for antioxidants, but yeah, this dose is on the lighter side compared to full liver supps that go 600mg+.
- 25mg Alpha Hydroxy Laxogenine — here for extra recovery and lean gains help. Human studies are thin, so treat it as a bonus, not the star.
- Everything's out in the open — doses listed for every ingredient. In a world of shady blends, this lets you see exactly what's up and if it fits your needs.
- Just one capsule a day — super easy to stick with. That's huge for something you take for weeks, 'cause consistency is what counts.
- No stims at all — zero caffeine or hype stuff. Pop it anytime, even at night, without jacking up your system or clashing with your pre.

Who Is This For?
- Seasoned bodybuilders wrapping up a tough cycle who want no-stim support with real aromatase action. That 37.5mg Androst 3,5-Dien-7,17-Dione is spot-on, backed by Tribulus and Saw Palmetto for hormone balance.
- Guys who want one easy capsule instead of buying four separate things. Gets you estrogen help, androgen support, and light antioxidants without blends.
- Folks hunting arimistane but in a fuller formula. PCT V pairs it with Tribulus for drive, Saw Palmetto for DHT, and NAC for basic protection.
- Dudes who feel motivation or libido dip after intense runs and need a supp for that. Tribulus shines more for those vibes than massive hormone shifts.
- Stim-sensitive lifters who don't want sleep issues from their hormone supp. This is 100% stim-free, so it fits without adding stress.
- People who demand full labels in shady categories. Doses are all there, so you can check it out honestly, no guesses.
How to Use
Take 1 capsule daily with water. It's for steady support, not quick hits, so consistency beats perfect timing. With a meal is smart, especially if you're stacking supps or have a touchy gut. No need to ease in—it's one cap, no stims. Use it every day, training or not, for that ongoing protocol. Stacks great with creatine, protein, fish oil, basics. For big liver focus, add a solo NAC or full supp, 'cause 125mg isn't heavy-duty. Don't mix with other hormone stuff unless you know the deal. Keep it cool and dry, lid on tight.
What to Expect
First 1-3 days, don't expect much—it's not a stim or pump product. Feeling nothing right away is normal; it's about building hormone support over time, not instant gym boosts. In week one, you might notice steadier mood, confidence, or drive more than workout power. By weeks 2-4, it clicks: Androst 3,5-Dien-7,17-Dione's estrogen control builds up, Tribulus and Saw Palmetto help the overall feel. NAC stays low-key. If you want a rush, look elsewhere; if it's gradual backup for your routine, this nails it.

Frequently Asked Questions
What is the main active ingredient in Blackstone Labs PCT V?
The formula’s primary active is Androst 3,5-Dien-7,17-Dione at 37.5mg per capsule. This ingredient is included for its aromatase-focused role, which is why it is the most mechanistically relevant part of the formula for post-cycle support.
Is PCT V a testosterone booster or a true post-cycle support formula?
It is better understood as a post-cycle support formula than a generic testosterone booster. The formula is built around arimistane for estrogen-management support, while Tribulus and Saw Palmetto provide supporting male vitality and androgen-balance roles rather than acting as reliably potent testosterone-elevating ingredients.
How much NAC is in PCT V, and is it enough for liver support?
PCT V contains 125mg of N-Acetyl Cysteine per serving. NAC is a valuable glutathione precursor, but 125mg is below the 600mg-or-higher doses commonly used in dedicated NAC or liver-support products, so this should be viewed as a supportive inclusion rather than a comprehensive liver formula.
Will I feel Blackstone Labs PCT V right away?
Probably not in the way you feel a pre-workout. This is a stim-free capsule product, so the expected benefits are gradual and cumulative over consistent daily use rather than immediate energy, focus, or pump effects.
Can I stack PCT V with a pre-workout?
Yes. PCT V contains no stimulants, so it stacks easily with pre-workouts, coffee, or other performance supplements without overlapping caffeine or stimulant load.
What does Saw Palmetto do in this formula?
Saw Palmetto berry extract at 160mg is included for DHT-pathway support through its association with 5-alpha-reductase modulation. In this formula, it broadens the hormonal-support profile beyond estrogen management alone.
Is Tribulus at 250mg a strong dose?
It is a moderate inclusion, especially given that it is a standardized extract rather than plain herb powder. Tribulus is more convincing for libido and subjective male vitality support than for dramatic testosterone increases, so that is the most realistic expectation here.
Does PCT V use a proprietary blend?
No. One of the formula’s strengths is full disclosure: every active ingredient and dose is clearly listed on the label.
Is Alpha Hydroxy Laxogenine a major reason to buy this product?
Not really. At 25mg, it is best viewed as a secondary adjunct for recovery and lean-mass support, while Androst 3,5-Dien-7,17-Dione remains the primary reason this formula exists.
Who should avoid using PCT V?
Anyone under 18, pregnant or nursing women, and people with hormone-sensitive conditions or those using prescription hormone-related medications should avoid self-prescribing this formula. Because it contains an aromatase-focused ingredient, it is not appropriate for casual or uninformed use.
