How Myo-Stack works
Myo-Stack attacks muscle growth from two non-hormonal directions. The ecdysteroid side comes from Rhaponticum carthamoides (also called Leuzea or Maral root), the classic Soviet-era source of 20-hydroxyecdysone, and Ajuga turkestanica, the plant that supplies turkesterone. Ecdysteroids are structurally different from androgens and do not act through the androgen receptor; instead, research shows they increase the rate of protein translation in muscle cells and, in cell studies on Ajuga turkestanica extract, lower the expression of myostatin and caspase-3, two signals that limit muscle growth and drive muscle breakdown.† Blackstone Labs uses a 100:1 Rhaponticum concentrate so the 250 mg blend carries a meaningful ecdysteroid load.
The second half is 50 mg of (25R)-5alpha-spirostan-2alpha,3beta,5alpha-triol-6-OH, a spirostane plant steroid in the same family as laxogenin and 6-keto-diosgenin. These brassinosteroid-type compounds are used in sports nutrition for their reported ability to increase protein synthesis and nitrogen retention without androgenic activity, which is why they show up in natural anabolic formulas.† Together the two mechanisms are meant to raise the rate at which your muscles pull in amino acids and turn them into new muscle protein, while reducing the signals that break muscle down.†
- Dual ecdysteroid sources: Rhaponticum carthamoides (20-hydroxyecdysone) plus Ajuga turkestanica (turkesterone) in one 250 mg blend.
- Laxogenin-type anabolic: 50 mg of a labeled spirostane compound, not a hidden proprietary amount.
- No hormonal activity: does not convert to testosterone or estrogen, no suppression, no PCT.
- Phospholipid and cyclodextrin tablet base: phosphatidylcholine and hydroxypropyl beta cyclodextrin are included to help absorption of poorly soluble plant steroids.
Benefits users report

How to take Myo-Stack
Take one tablet two to three times per day with food. Do not exceed four tablets in a day. A common schedule is one tablet with breakfast, one with your pre-workout meal and, on the three-a-day protocol, one with dinner. Taking it with a meal that contains some fat helps absorption of the plant steroids. One 60-tablet bottle lasts 30 days at two tablets daily or 20 days at three. Myo-Stack does not require cycling or PCT, but most users run it for 4-8 weeks at a time; buyers at Tiger Fitness most often report strength changes within the first couple of weeks and body composition changes over the full bottle.

Myo-Stack side effects and warnings
Myo-Stack is non-hormonal, so it does not carry the testosterone suppression, estrogen conversion, hair loss or liver strain concerns of prohormones, and it contains no stimulants. Reported side effects are rare and typically limited to mild stomach upset when taken without food. Ecdysteroids such as ecdysterone are on the WADA monitoring program and some sports organizations restrict them, so tested athletes should check with their governing body before use.

Blackstone Labs Myo-Stack FAQ
Is Myo-Stack a steroid or a prohormone?
No. Myo-Stack contains plant ecdysteroids and a laxogenin-type spirostane. None of them bind the androgen receptor or convert to testosterone or estrogen, so it is not a steroid, a prohormone or a SARM.
Do I need PCT after Myo-Stack?
No. Because it is non-hormonal it does not suppress natural testosterone, so no post cycle therapy or on-cycle support is needed. If you stack it with a prohormone such as Chosen1, follow that product's PCT guidance.
How much turkesterone is in Myo-Stack?
Ajuga turkestanica extract is part of the 250 mg Myostatin and Anabolic Proprietary Blend along with Rhaponticum carthamoides 100:1 extract. Blackstone Labs does not publish a separate turkesterone milligram figure on the label.
How long does Myo-Stack take to work?
Verified buyers at Tiger Fitness most often report strength and muscle fullness changes within the first 1-2 weeks, with size and body composition changes over a full 4-8 week run.
Can women take Myo-Stack?
Yes. Ecdysteroids and laxogenin-type compounds are non-androgenic, so adult women can use Myo-Stack without the masculinization risk of hormonal products. Do not use while pregnant or nursing.
Can I stack Myo-Stack with a prohormone?
Yes. Many users add Myo-Stack on top of a Blackstone prohormone cycle for extra protein synthesis through a separate, non-hormonal pathway, and keep running it during PCT to help hold gains.†
Will Myo-Stack show up on a drug test?
It is not a hormonal product, but ecdysterone is on the WADA monitoring list and the label warns it may contain ingredients banned by some sports organizations. Tested athletes should check their own list before using it.
How many tablets a day should I take?
The label calls for one tablet two to three times daily with food and sets a hard limit of four tablets per day. Two per day gives a 30-day bottle; three per day gives 20 days.
Does Myo-Stack contain stimulants?
No. It has 0 mg caffeine and can be taken at any time of day, including with your evening meal.
