Follistatin 315 Cost in 2026: What to Expect
Follistatin 315 is among the more expensive research peptides, typically priced at $200–$500 per vial depending on vial size, purity, and source. Here is what drives the cost and how it compares to related compounds.
Follistatin 315 Price Range
Research chemical vendors
$150–$400 per vial
Not for human use; quality varies
Specialty compounding pharmacy
$250–$600 per cycle
Physician prescription required; limited availability
International pharmacy
$200–$500
Import legality is a gray area
Follistatin 315 is not available through standard US pharmaceutical channels and is not FDA-approved.
Why Is Follistatin 315 Expensive?
Several factors drive the relatively high cost:
Complex synthesis: Follistatin is a larger protein than most research peptides, making synthesis more technically demanding and costly
Low production volume: Limited demand compared to popular peptides (semaglutide, BPC-157) means no economies of scale
Purification requirements: Achieving high-purity follistatin requires multiple purification steps
Limited vendor competition: Few manufacturers produce research-grade follistatin, limiting price competition
Follistatin 315 vs. Follistatin 344: Which Is Cheaper?
In practice, prices for Follistatin 315 and Follistatin 344 are similar — both in the $150–$500 range per vial from research suppliers. Follistatin 344 is slightly more commonly available due to higher research interest (stronger myostatin inhibition for body composition applications), which may give it marginally more competitive pricing.
Key difference for cost planning: Follistatin 315 circulates more systemically (longer half-life in circulation), so some protocols use less frequent dosing — which may reduce monthly cost compared to 344.
Follistatin 315 Cost Per Month
Dosing frequency for research protocols is typically 50–100 mcg every other day to weekly. Monthly cost estimation:
Weekly dosing: 4 doses/month × ($50–$150/dose from vial) = $200–$600/month in peptide cost alone
Does not include consultation, labs, or injection supplies
Given the significant cost and the limited human evidence base, follistatin should be considered carefully relative to better-studied (and often less expensive) alternatives for similar goals.
Frequently Asked Questions
How much does follistatin 315 cost per month?
Monthly costs typically run $200–$600 for the peptide alone, depending on source, dosing frequency, and vial size. First-month costs are higher with consultation and lab setup.
Is follistatin 315 cheaper than follistatin 344?
Pricing is broadly similar — both in the $150–$500/vial range. Availability may give Follistatin 344 marginal pricing advantages in some markets.
Is follistatin 315 worth the cost?
Follistatin research is compelling in animal models, but human evidence is minimal. At current prices, it represents a significant expense for a compound with limited proven human benefit. Discuss with your physician whether the cost-benefit ratio makes sense for your specific goals.
Where can I buy follistatin 315?
Through licensed compounding pharmacies (with physician prescription, limited availability) or research chemical vendors (not for human use). Do not purchase from unverified international suppliers without independent purity verification.
