MASSACHUSETTS INVESTORS GROWTH STOCK FUND
Supplement dated December 1, 2000 to the Current Prospectus
This Supplement describes the fund's class J shares, and it supplements certain
information in the fund's Prospectus dated April 1, 2000. The caption headings
used in this Supplement correspond with the caption headings used in the
Prospectus.
Class J shares are available for purchase only by Japanese investors. Class J
shares may only be offered or sold outside the United States and this supplement
does not constitute an offer of class J shares to any person who resides within
the United States.
1. RISK RETURN SUMMARY
Performance Table. The Performance Table is not included because the fund's
Class J shares has not had a full calendar year of investment operations.
2. EXPENSE SUMMARY
Expense Table. The "Expense Table" describes the fees and expenses that you
may pay when you buy, redeem and hold shares of the fund. The table is
supplemented as follows:
Shareholder Fees (fees paid directly from your investment)
Class J
Maximum Sales Charge (Load) Imposed on Purchases
(as a percentage of offering price)................. 4.00%(1)
Maximum Deferred Sales Charge (Load) as a percentage
of original purchase price or redemption proceeds,
whichever is less).................................. None
Annual Fund Operating Expenses (expenses that are deducted from fund assets)
Management Fees........................................... 0.33%
Distribution and Service (12b-1) Fees(2).................. 1.00%
Other Expenses(3)......................................... 0.19%
-----
Total Annual Fund Operating Expenses...................... 1.52%
-----------------------
(1) Class J shares are sold in Japan through financial institutions. The
sales charge (load) paid by an investor differs depending upon the
financial institutions through which the investment is made, but will not
exceed 4%. These sales charges (loads) are fully disclosed in the fund's
Japanese prospectus, which is provided to investors upon sale of the
fund's Class J shares.
(2) The fund adopted a distribution plan under Rule 12b-1 that permits it to
pay marketing and other fees to support the sale and distribution of
class J shares and the services provided to you by your financial adviser
(referred to as distribution and service fees).
(3) The fund has an expense offset arrangement which reduces the fund's
custodian fee based upon the amount of cash maintained by the fund with
its custodian and dividend disbursing agent and the fund may enter into
other similar arrangements and directed brokerage arrangements (which
would also have the effect of reducing the fund's expenses). "Other
Expenses" do not take into account these expense reductions, and
therefore do not represent the actual expenses of the fund. Had these fee
reductions been taken into account, "Total Annual Fund Operating
Expenses" for Class J shares would be lower, and would be estimated to be
1.51%.

other mutual funds.

o You invest $10,000 in the fund for the time periods indicated and you
redeem your shares at the end of the time periods;
o Your investment has a 5% return each year and dividends and other
distributions are reinvested; and
o The fund's operating expenses remain the same.

4. HOW TO PURCHASE, EXCHANGE AND REDEEM SHARES
The discussion of "How to Purchase, Exchange and Redeem Shares" is supplemented
as follows:
How to Purchase Shares. You can establish an account by having your
financial institution process your purchase. The minimum initial investment and
the minimum subsequent investment amounts differ depending upon the financial
institution through which the investment is made. These minimums are fully
disclosed in the fund's Japanese prospectus, which is provided to investors upon
sale of the fund's class J shares.
How to Exchange Shares. Exchanges of class J shares of the fund for class J
shares of other MFS funds is permitted only if the funds are sold in Japan
through the same distributor and the distributor permits exchanges. Exchange
privileges are fully disclosed in the fund's Japanese prospectus, which is
provided to investors upon sale of the fund's class J shares.
How to Redeem Shares. You may withdraw all or any portion of the value of
your account on any date the fund is open for business by selling your shares to
the fund through a financial institution, who may charge you a fee. If the
financial institution receives your order prior to the close of regular trading
on the New York Stock Exchange and communicates it to MFS before the close of
the business on the same day, you will receive the net asset value calculated on
that day, reduced by an amount of any income tax required to be withheld.
