Best Follistatin vendors in 2026
Buying Follistatin: what the field looks like
We track 7 in-stock Follistatin listings across 3 US retail vendors, and re-read every one of them each night. Ranking below is by cost per milligram, which is the only figure that compares a 5mg vial against a 10mg one honestly.
The cheapest source works out at $22.45/mg. Prices across this field sit close together, so the vendor you pick matters less here than it does on most compounds — buy on stock and shipping instead.
The lowest total cart is $69.99 at goalphalabs. That is the cheapest way to hold Follistatin at all, which is a different question from the best cost per milligram — the two are the same vendor only sometimes.

Bulk and multi-vial pricing
Ranked by cost per milligram. A pack is always a bigger cart than a single vial — the question these answer is whether it is cheaper per milligram, not whether it is cheaper.
How we rank these vendors
Vendors are ordered by cost per milligram of their cheapest in-stock single vial. Nothing else moves the order — not commission, not whether a vendor has a partner programme, not how long we have tracked them.
The score beside each vendor is a listing-quality score, not a purity or trust score. We have no laboratory and we do not test anything. It is built from figures we measure ourselves: where the vendor's prices sit inside each compound's own field, how many compounds they carry, how reliably their listings stay in stock, and how many certificates they publish. Every input is shown beside the number.
Prices older than 48 hours are dropped rather than shown stale, so a vendor missing from this page is usually a vendor whose site we could not read last night.
Common questions
Who sells Follistatin cheapest right now?
goalphalabs, at $22.45 per milligram and $69.99 for the cheapest single vial. That is across 3 US retail vendors, checked within the last 24 hours.
How much should Follistatin cost per mg?
The median across 3 vendors is $22.45/mg. Anything at or under that is a fair price; the cheapest we can find is $22.45/mg, and the top of the market runs to $88.20/mg.
Are multi-vial kits cheaper?
2 vendors sell Follistatin in multi-vial packs. They are usually cheaper per milligram and always a larger cart, so they are ranked separately above rather than mixed into the single-vial list.
Do you sell Follistatin?
No. We sell nothing and ship nothing. Every link goes to the vendor's own store, and some of them pay us a commission — those are labelled on the row, and commission never affects the ranking, which sorts on price alone.
