One more angle: can peptide purchases be claimed as medical expenses for tax purposes? If I'm using BPC-157 for a legitimate medical issue under the guidance of a healthcare provider?

Very unlikely. For the IRS medical expense deduction (Schedule A, subject to the 7.5% AGI threshold):

• The expense must be for the "diagnosis, cure, mitigation, treatment, or prevention of disease"
• It must be for substances that are "legally procured"
• Research peptides are sold as "not for human consumption" — claiming them as a medical expense would be contradictory to how they're legally marketed

Prescription GLP-1 medications (semaglutide, tirzepatide) obtained through a pharmacy with a prescription are absolutely deductible medical expenses. But research peptides from peptide suppliers? I wouldn't try it.

That said, if you're getting compounded peptides from a compounding pharmacy with a prescription, that's a different story — those are legitimate pharmacy purchases and should be deductible just like any other prescription medication. Talk to your CPA about the specifics.

Summary of the most tax-efficient crypto payment strategies for peptide purchases:

1. Best: Buy stablecoin (USDC/USDT) and spend immediately. Zero capital gain, simple records, still gets the crypto discount.
2. Good: Buy Bitcoin and spend within the same session. Minimal capital gain/loss, low reporting burden.
3. Avoid: Spending Bitcoin you've held for months/years at a much lower cost basis. Could generate meaningful capital gains you need to report and pay tax on.

Crypto tax software annual cost: $49-199 depending on transaction volume. Most plans handle the number of transactions a typical peptide buyer would have. Koinly has a free tier for up to 10,000 transactions that works for most people.

Important thread. Tax compliance isn't sexy but it matters. Nothing in this thread constitutes tax advice — consult a qualified tax professional for your specific situation. The IRS has been increasing crypto enforcement, so getting this right is worth the effort even for small amounts.
