What is FOLLISTATIN?
Follistatin binds myostatin, the protein that limits how much muscle you can carry. What it does when injected is a much smaller claim than what it does in the studies people have seen.
Also sold as follistatin-344 or activin-binding protein.
Myostatin is your body's brake on muscle growth. Follistatin binds it and takes it out of action, which in principle releases that brake. The animals bred or gene-edited to lack myostatin are genuinely enormous, and that is where the reputation comes from.
FOLLISTATIN benefits
- Binds myostatin, the protein that limits muscle growth
- Also binds activin, which is involved in the same pathway
- Not androgenic, so nothing is suppressed and no post-cycle therapy applies
- Short run lengths, typically ten days
FOLLISTATIN dosage
- Standard
- 100mcg per day
- Run length
- 10 days, then a long break
- Route
- Subcutaneous
- Half-life
- Short, measured in hours
- Per vial
- 1mg, which is a 10 day run
- Frequency
- Once daily
100mcg a day for ten days is the protocol people use, and one vial is exactly that.
Reconstitute with bacteriostatic water. The reconstitution guide covers the method and the dosage calculator works out how much water to add for the dose you want.

Who is FOLLISTATIN for?
Advanced users who have read the actual evidence and want to try it anyway. That is an honest description of the audience for this product.
If you are drawn here by what you have seen about myostatin, read the warning below first. The compounds in this catalogue with the best evidence behind them for adding muscle are the injectable steroids, not this.
Read this before buying. The dramatic myostatin results you have seen did not come from injecting this. Animals lacking myostatin are bred that way or gene-edited; the enormous cattle and dogs in those photographs are not the result of a peptide course. Injected follistatin has a short half-life and poor systemic availability, and there are no controlled human trials showing it produces meaningful muscle growth. We would rather say that than take your money on an implication. There is also a theoretical concern worth knowing: follistatin affects the same pathway in reproductive tissue, and long-term effects in humans are simply not characterised. It is not androgenic, so nothing is suppressed and no post-cycle therapy applies. Reconstituted vials go in the fridge. Not for anyone under 18, and not for women who are pregnant or breastfeeding.
How to use FOLLISTATIN
Reconstitute with bacteriostatic water and refrigerate once mixed. Inject subcutaneously once daily for ten days.
Frequently asked questions
Will it work like the myostatin-knockout animals?
No, and this is the thing to be clear about before spending the money. Those animals lack myostatin from birth, either through breeding or gene editing, across their entire development.
Injecting a peptide that binds circulating myostatin for a few hours a day over ten days is a completely different proposition. The photographs sell the product; they do not describe what it does.
Is there human evidence?
Very little. There are no controlled trials showing injected follistatin produces measurable muscle growth in humans.
What exists is mechanism, animal work and user reports. That is not nothing, but it is a long way short of what the marketing around this compound implies.
Why is the run only ten days?
That is the protocol that circulates, and one vial happens to be exactly that at 100mcg a day.
There is no strong evidence behind the ten days specifically. It is convention rather than a tested schedule, which is itself worth knowing.
Does it suppress anything?
Not testosterone, so no post-cycle therapy. Follistatin is not androgenic.
It does act on the activin pathway, which has roles in reproductive tissue, and the long-term consequences of that in humans are not characterised.
Is it worth the money?
On the evidence, it is difficult to argue that it is, and we would rather say so. It is among the more expensive peptides here and has the least behind it.
If you want it because you are curious and can afford the experiment, that is a legitimate reason. If you are expecting it to change your physique, the evidence does not support that.
